You have taken the decision to benefit from the unlimited possibilities of allceramic. IPS e.max delivers high strength and highly aesthetic materials for the PRESS and the CAD/CAM technology. The IPS e.max products are unique. They are recognized for their outstanding properties as well as exceptional versatility and flexibility – and they produce results with maximum aesthetics. The components for the PRESS technique include the highly aesthetic glass-ceramic IPS e.max Press ingots and the glass-ceramic IPS e.max ZirPress ingots for pressing onto zirconium oxide. Depending on the case requirements, two types of materials are available for CAD/CAM techniques: the innovative IPS e.max CAD glass-ceramic blocks and the high-strength zirconium oxide IPS e.max ZirCAD. The IPS e.max System is further enhanced by the nano-fluorapatite layering ceramic IPS e.max Ceram, which is used as a veneering material for all the IPS e.max components – either glass-ceramics or zirconium oxide ceramics. This proves that really exceptional all-ceramic systems are well designed. The system allows you to take advantage of a single, standardized layering scheme to offer your dentists and their patients restorations with maximum individuality and naturalness. 3 IPS e.max Press – ® P R O D U C T I N F O R M AT I O N M AT E R I A L USAGE IPS e.max Press is a lithium disilicate glass-ceramic ingot for the PRESS technology. The manufacturing process produces homogeneous ingots in various degrees of opacity having a flexural strength of 400 MPa. IPS e.max Press ingots are therefore the pressed ceramic ingots featuring the highest strength. The ingots are pressed in Ivoclar Vivadent press furnaces and produce accurately fitting restorations. Compared to IPS Empress® ingots, IPS e.max Press are larger in diameter, i.e. more volume, which allows more restorations to be produced per press cycle. This increases the economic efficiency and working speed. The pressed, tooth-coloured and highly aesthetic frameworks are then veneered using IPS e.max Ceram. Indications – Anterior and posterior crowns – 3-unit anterior bridges – 3-unit bridges up to the second premolar as the abutment tooth – Press-over electroplated single crowns – Implant superstructures for single restorations (anterior and posterior region) – Implant superstructures for 3-unit bridge restorations up to the second premolar as the abutment tooth – Primary telescope crowns CTE (100–400°C) [10-6/K]* 10.2 CTE (100–500°C) [10-6/K]* 10.5 Flexural strength (biaxial) [MPa]* 400 Fracture toughness [MPa m0.5]* 2.75 Modulus of Elasticity [GPa] Vickers hardness [MPa] Contraindications – Molar bridges with the first molar as a pontic – 4- and multi-unit bridges – Inlay-retained bridges – Very deep, subgingival preparations (adhesive cementation) – Patients with severely reduced residual dentitions – Bruxism Important processing restrictions Failure to observe the following restrictions may compromise the results achieved with IPS e.max Press: – The frameworks and the connectors must not fall below the required minimum thickness – Veneering ceramics other than IPS e.max Ceram must not be used – Do not stack two or more IPS e.max Press ingots in a single investment ring – Metal-ceramic opaquers must not be used with press-over electroplated frameworks 95 5800 Chemical resistance [µg/cm2]* 40 Press temperature EP 600 [°C] 915–920 Side effects If a patient is known to be allergic to any of the components in IPS e.max Press, the material should not be used. *according to ISO 6872 4 COMPOSITION IPS e.max Press ingots and the processing accessories consist of the following main components: – IPS e.max Press Ingots Components: SiO2 > 57 % wt.

Can other press furnaces be used to press IPS e.max Press ingots? IPS e.max Press is specifically coordinated with the Ivoclar Vivadent press furnaces (EP 500, EP 600, and EP 600 Combi). If other press furnaces are used, the parameters have to be adjusted accordingly by the user. The material can be used for 3-unit bridges from the first premolar to the first molar as abutment. However, the molar must be given a fully anatomical design and connector dimensions of 20 mm2 (IPS Connector C6) must be observed. May IPS e.max Press frameworks be blasted using Al2O3 after completion (on the cavity side)? Is IPS e.max Press suitable for the fabrication of fully anatomical crowns? IPS e.max Press can be used for fully anatomical crowns. However, the opacity of the ingots somewhat limits the aesthetic results. This fact must be considered during the fabrication. IPS e.max Press restorations must not be sand blasted prior to cementation, since this would damage the ceramic surface and alter its properties. Prepare the internal surfaces by etching. Is IPS e.max Press suitable to press-over Captek or other metal frameworks? May IPS e.max Ceram Margin materials also be used for IPS e.max Press? IPS e.max Press cannot be pressed-over Captek and other metal frameworks, since the corresponding CTE values are not coordinated with each other. IPS e.max Ceram Margin materials must not be used on the glass-ceramic materials (IPS e.max Press and CAD), since the firing temperatures are too high and the reduction for the shoulder would weaken the restoration. Can IPS Empress Universal Shades, Stains and Glaze be used for IPS e.max Press? Can IPS e.max Press restorations also be conventionally cemented? IPS Empress Universal Shades, Stains, and Glaze have been especially developed for the IPS Empress System and thus cannot be used for IPS e.max products. IPS e.max Press restorations may be either adhesively or conventionally cemented. For conventional cementation, however, an appropriately retentive preparation design must be observed. If this is not possible, adhesive cementation, e.g. with Variolink® II and Multilink® should be used. Vivaglass CEM is available for conventional cementation. We advise against the use of traditional phosphate cements, since they negatively influence the light transmission through the all-ceramic and compromise the aesthetic appearance of the all-ceramic restorations. Can IPS e.max Alox plungers also be used for IPS Empress? IPS e.max Alox plungers are exclusively for the IPS e.max System and the corresponding investment ring system specifically developed for this purpose. Since the diameter has been increased, the Alox plunger would not fit into the IPS Empress investment ring system. Can the IPS e.max Alox Plunger Separator also be used for other pressed ceramics, such as IPS Empress Esthetic? The IPS e.max Alox Plunger Separator can only be used for IPS e.max Press and IPS e.max ZirPress ingots, since the press temperature of the IPS Empress Esthetic ingots of 1075 °C (1967 °F) is too high and results in the Separator losing its effect. 6 INGOT CONCEPT The shading and opacity control of the IPS e.max Press ingots is based on a newly developed, translucency/opacity concept. The system is flexibly organized and can be used with both A–D and Chromascop shades. The individual levels of the concept are determined by indications and application. The individual opacity and translucency levels are distinguished by means of a colour code. A–D Shades Shade system Medium Opacity High Opacity Processing technique Chromascop MO 0 MO 1 MO 2 HO IPS e.max Press MO (Medium Opacity) Because of their opacity, ingots in the shades MO 0 – MO 4 are ideally suitable for the fabrication of frameworks on vital or slightly discoloured preparations and provide the ideal basis for restorations in A-D and Chromascop shades with a natural appearance. The ingots are shaded according to specific group shades. The fluorescence of the ingots decreases with the intensity of the shading. The IPS e.max Press HO (High Opacity) ingots are available in one shade and, due to their higher opacity, are ideal for the fabrication of frameworks on devitalized or severely discoloured preparations, as well as to partially cover metal core build-ups. The high opacity adequately masks the substructure and enables the fabrication of lifelike restorations even in situations with difficult or very dark preparations. IPS e.max Press ingots Normal light – opacity 7 MO 3 MO 4 PRODUCT OVERVIEW AND DESCRIPTIONS IPS e.max Press Basic Kit MO (Medium Opacity) The IPS e.max Press Basic Kit is comprised of all the ingots, as well as the necessary processing accessories.

The opaquers are available in 5 shades (0–4), which are selected in accordance with the desired tooth shade and fired. Thus, they enable a homogeneous bond to both the electroplated framework and the IPS e.max Press ingots. Delivery form: IPS e.max Press Opaquer Kit – 5x IPS e.max Press Opaquer, 3 g each; Shades: 0, 1, 2, 3, 4 The IPS e.max Press MO (Medium Opacity) ingots are available in 2 sizes and 5 shades (MO 0, MO 1, MO 2, MO 3, MO 4). IPS e.max Press MO (Medium Opacity) Ingots Delivery form: IPS e.max Press MO Ingots – 5x 5 IPS e.max Press Ingots; Shades: MO 0, MO 1, MO 2, MO 3, MO 4 – 5x 3 IPS e.max Press Ingots L; Shades: MO 0, MO 1, MO 2, MO 3, MO 4 8 IPS e.max Press HO (High Opacity) Ingots IPS e.max Press HO (High Opacity) ingots are available in 2 sizes and one shade (HO). Delivery form: IPS e.max Press HO Ingots – 1x 5 IPS e.max Press Ingots; Shade: HO – 1x 3 IPS e.max Press Ingots L; Shade: HO IPS e.max Alox Plunger The ceramic ingot, in its softened state, is pressed into the hollow space in the investment ring by means of the IPS e.max Alox plunger. It features a larger diameter and is slightly shorter than the existing IPS Empress Alox plunger and is thus only suitable for the IPS e.max investment ring system. Both ends of the Alox plunger are rounded, which makes both sides suitable for pressing. In this respect, the new plunger is different from the existing IPS Empress press plungers. Delivery form: IPS e.max Alox Plunger – 2 IPS e.max Alox Plungers IPS e.max Alox Plunger Separator The IPS e.max Alox Plunger Separator prevents the ingot from sticking to the Alox plunger during pressing and cooling in the investment ring. The cold Alox plunger is inserted into the recess and rotated. The powder adheres to the surface and thus forms a separating layer. A very small amount of Separator is sufficient. The cold, prepared Alox plunger is subsequently inserted into the preheated investment ring immediately before pressing. Delivery form: IPS e.max Alox Plunger Separator – 1x IPS e.max Alox Plunger Separator, 200 mg IPS e.max Investment Ring System The IPS e.max Investment Ring System is used to sprue the contoured restorations. The base has been enlarged so that the IPS Silicone Ring optimally fits onto the base. The larger IPS e.max investment ring base thus substantially differs from the IPS Empress investment ring base, which prevents the two bases from being confused.

IPS e.max Press Invex Delivery form: IPS e.max Press Invex – 1x IPS e.max Press Invex, 1 l The light-curing IPS Natural Die Material simulates the shade of the prepared tooth and thus represents the optimum basis for natural shade reproduction of the given oral situation when fabricating allceramic restorations. IPS Natural Die Material is available in 9 shades. The shades were newly arranged and the assortment now contains all the shade variations necessary for the fabrication of lifelike allceramic restorations: – 1 shade to imitate bleached preparations (ND 1) – 1 shade to imitate secondary dentin that demonstrates an intensive shade (ND 6) – 1 shade to imitate severely discoloured / devitalized preparations (ND 9) IPS Natural Die Material The following chart shows the arrangement and designations of IPS Natural Die Material shades compared to those of the IPS Empress Die material.

The individual shades of the Chromascop are logically arranged and therefore allow shades to be determined accurately and efficiently. The 20 shades are divided into five shade groups. In addition, the Chromascop Bleach shade group comprises four very light shades. Once the basic hue has been established, the most suitable shade is chosen from within the shade group. All superfluous effects (eg cervical and translucent areas, severe discolourations in the incisal area and dentin as well as superficial characterizations) have been left out, making the selection of the proper shade much easier. IPS Natural Die Material Shade Guide In order to facilitate the reproduction of the tooth shade, dentists have the possibility of communicating the shade of the preparation of the given clinical situation to the dental laboratory using the IPS Natural Die Material shade guide. In this way, the fabrication of all-ceramic restorations is facilitated and a patient's individual characteristics can be taken into consideration. IPS e.max Press Shade Guide IPS e.max Press shade guide makes it possible for the dentist to choose the shade of the ingot to be used for the case. The shade tabs show the shade of the ingot after pressing. 12 P R E P A R AT I O N G U I D E L I N E S A N D M I N I M U M T H I C K N E S S E S Successful working with IPS e.max Press can only be ensured if the following guidelines and layer thicknesses are observed. Crowns Evenly reduce the anatomical shape and observe the stipulated minimum thicknesses. Prepare a circular shoulder with rounded inner edges or chamfer with an angle of approx. 10°–30 °. The width of the circular shoulder/chamfer is approx. 1 mm. Reduction of the crown third – incisal or occlusal areas – by approx. 2 mm. For anterior crowns, the labial and palatal/lingual part of the tooth should be reduced by approx. 1.5 mm. 2.0 2.0 1.0 1.5 1.0 1.5 1.5 1.5 1.5 1.0 1.0 6° 2.0 Bridges The maximum acceptable bridge pontic width varies from patient to patient. It depends on the position, size, and state of the teeth, as well as the position of the abutments within the tooth arch. The measurements to determine the bridge pontic width should be done on the unprepared tooth. – In the anterior region (up to the canine), the bridge pontic width should not exceed 11 mm – In the premolar region (from the canine up to the 2nd premolar), the bridge pontic width should not exceed 9 mm Occlusal force Maximum Pontic Span Maximum Pontic Span 9 mm Premolar to Canine 11 mm Anterior 13 FRAMEWORK DESIGN CRITERIA The framework design is the key to the success of durable all-ceramic restorations. The more attention given to framework design, the better the final results and the clinical success will turn out to be. The following basic guidelines have to be observed: – The framework material is the high-strength component of your restoration and must, therefore, always make up at least 50 % of the total layer thickness of the restoration. – In large preparations, the excess in available space must be compensated by the design of the framework and not by the layering material. – If possible, the connector design should be extended in the vertical direction, rather than in the sagittal or horizontal direction. – Especially in anterior bridges, it is not always possible to establish the necessary connector dimensions with regard to the sagittal (linguo-vestibular) region. In these cases, the connector dimensions must always be increased in the vertical (incisocervical) direction. – The translucency of the IPS e.max Press MO ingots is similar to that of natural teeth and has been coordinated with the stipulated layer thicknesses. – A reduction of the framework thickness is always related to a reduction in strength, in value and in shade stability of the restoration. – If only limited space is available, non-aesthetic areas (e.g. palatal or occlusal surfaces) do not necessarily have to be covered with layering material. In such cases, the corresponding areas of the framework are designed in their fully anatomical shape and subsequently glazed.

Design for partial veneers 16 C E M E N TAT I O N For the cementation of the IPS e.max restorations, you may select between the tried-and-tested adhesive luting composites and cements from the coordinated assortment of Ivoclar Vivadent. Adhesive cementation achieves a sound bond between the preparation and the cementation material, while conventional cementation requires a retentive preparation to ensure the durability of the IPS e.max restorations.

The application of a sealer is recommended to harden the surface and to protect the stone die. However, the sealer layer must not result in any changes of the dimensions of the stone die. Subsequently, the spacer is applied as described below. Please make sure to consider the expansion of the investment material when applying the spacer. – For single crowns, the spacer is applied in two layers up to max. 1 mm from the preparation margin (spacer application 9–11 µm per layer) – Two sealer layers are also applied for bridge reconstructions. – An additional layer is applied to the intercoronal surfaces of the abutments (facing the pontic). This layer prevents undesired friction. Sealer application for bridges Sealer application for single restorations Sealer application in 2 layers….. For bridges, 2 layers…. …up to max. 1 mm from the preparation margin ... and a third layer to the intercoronal surfaces are to be applied 18 Contouring Contouring may vary depending on the available space. However, it must provide shape and cusp support in order to achieve an even layer thickness of the veneering ceramic. Always provide a shape- and cusp-supporting design and observe the minimum thicknesses. For bridge reconstructions, fabricating a full wax-up of the restoration is recommended. To ensure the correct dimensions of the connectors between bridge pontic and bridge abutment, IPS Connectors may be used. Variant A: Ideal space Variant B: Limited space If enough space is available, the wax-up is reduced in the buccal/labial, as well as in the palatal/lingual areas. In other words, the share of the restoration that will be built-up using layering material after pressing has to be reduced in accordance with the images below. The relation between the framework thickness (min. 0.8 mm) and the layering material must be observed (i.e. at least 50% of the total thickness is the framework). If space is limited, the wax-up is only reduced in the buccal and incisal areas. The palatal/lingual area may be pressed with a fully anatomical design. In other words, the share of the restoration that will be built-up using layering material after pressing has to be reduced in accordance with the images below. The relation between the framework thickness (min. 0.8 mm) and the layering material must be observed (i.e. at least 50% of the total thickness is the framework).

Leave the fully anatomical design in the palatal/lingual area and do not reduce. 19 Sprueing Always place the sprues in the direction of flow of the ceramic and at the thickest part of the wax-up in order to achieve unimpeded flow of the viscous ceramic material. The 100 g or 200 g investment ring base is selected depending on the number of objects to be invested. Bridges must be pressed using the 200 g investment ring system. The following sprueing guidelines must be observed: Single Crowns 3-Unit Bridges 100 g and 200 g 200 g only 2.5 – 3 mm 2.5 – 3 mm min. 3 mm, max. 8 mm min. 3 mm, max. 8 mm max. 15–16 mm max. 15–16 mm Thickest part of the wax-up At both bridge abutments; no sprue at the pontic Sprueing angle to the wax object axial axial Sprueing angle to the investment ring base 45–60° 45–60° Design of the attachment points rounded and slightly tapered; no sharp angles or edges rounded and slightly tapered; no sharp angles or edges Distance between objects min. 3 mm min. 3 mm Distance to the silicone ring min. 10 mm min. 10 mm A dummy object must be invested with very delicate single wax objects With extremely delicate dies (e.g. mandibular anteriors) attach an additional sprue to the bridge pontic in the axial direction) to provide additional stability.

The corresponding IPS silicone ring with matching ring gauge is used for that purpose. We recommend the following procedure to determine the accurate wax weight: – Weigh the ring base (seal the opening of the ring base with wax). – Position the objects to be pressed on the ring base and attach them with wax. Weigh again. – The difference between the two values is the weight of the wax used. Small Ingot Large Ingot (L) Wax weight up to max. 0.75 g up to max 2 g Investment Ring System 100 g and 200 g 200 g only Please refer to the Instructions for Use of the corresponding investment material regarding the detailed processing parameters. – Do not apply a debubblizer to the wax objects. – Mix investment material. The investment material contains quartz powder. Therefore, the inhalation of dust must be avoided. – Use a suitable instrument for the fine investment of the cavity. Make sure that the delicate wax margins are not damaged. – Carefully position the IPS Silicone Ring on the investment ring base without damaging the wax objects. The IPS Silicone Ring must sit flush on the investment ring base. – Subsequently, carefully fill the investment ring with investment material up to the marking and position the ring gauge with a hinged movement. – Allow the investment material to set without manipulating the investment ring. – Do not use IPS PressVEST for investment over the weekend to prevent crystallization. Use the IPS Silicone Ring for investment. Pour the investment material slowly and carefully. Fill investment ring up to the marking and position the ring gauge with a hinged movement. 23 Preheating After the stipulated setting time of the respective investment material (IPS PressVEST or IPS PressVEST Speed), the investment ring is prepared for preheating as follows: – Remove the ring gauge and ring base with a turning movement. – Carefully push the investment ring out of the IPS Silicone Ring. – Remove rough spots on the bottom surface of the investment ring with a plaster knife and check the 90° angle. – Investment material residue must not enter the sprues. Blow into the sprues if necessary. – If several investment rings are preheated together, mark them with the respective ingot shade.

If several Speed investments are required, they should be invested with a time difference and placed in the preheating furnace at intervals of approximately 20 minutes. When placing the investment rings in the preheating furnace, make sure that the furnace temperature does not drop too much. The indicated holding time starts when the preheating temperature is reached. Do not preheat IPS e.max Press ingots and Alox plunger. In order to ensure smooth working procedures in the laboratory on a daily basis, impeccable functioning of the infrastructure and the preheating furnaces is essential. This includes their maintenance, cleaning with a vacuum cleaner in a cool state as well as regular checks of the temperature controls and heating elements, etc, by the manufacturer. 24 Calibration The furnace must be regularly calibrated to achieve optimum press results. Calibrate the EP500 with the Temperature Checking Set 2 and the EP600 with the Automatic Temperature Checking Set 1. EP 500 1. Switch on the EP500 and allow the furnace to heat up to the stand-by-temperature of 700 °C/ 1292 °F. Hold this temperature for at least 30 minutes. 2. Select a program for the staining technique T=1075 °C/1967 °F. Run the program with the furnace empty. After activation of the holding time H=20 min., which the EP500 does automatically, interrupt the program after 15 minutes (set timer) by pressing the STOP key twice.

Remove the investment ring from the furnace immediately after the program is completed and close the furnace. Place the investment ring on the cooling grid and allow it to cool to room temperature. The grid ensures quick and even cooling of the investment ring and prevents undesired heat accumulation. 27 Divesting After cooling to room temperature (approximately 60 minutes), the investment ring may show cracks. These cracks developed (immediately around the Alox plunger) during cooling as a result of the different CTEs of the various materials (Alox plunger, investment material, and pressed materials). They do not compromise the press result. Divest the investment ring as follows: – Mark the length of the Alox plunger on the cooled investment ring. – Separate the investment ring using a separating disk. This predetermined breaking point enables reliable separation of the Alox plunger and the ceramic material. – Break the investment ring at the predetermined breaking point using a plaster knife. – Rough divestment is carried out with glass polishing beads at 4 bar (60 psi) pressure. – Fine divestment is carried out with glass polishing beads at 2 bar (30 psi) pressure. – Do not use Al2O3 for rough or fine divestment. – When divesting the object, blast from the direction indicated in the schematic below and observe the appropriate distance in order not to damage the object margins. – Any ceramic residue on the Alox plunger is removed with Al2O3 (type 100 microns). Mark the length of the Alox plunger Separate the investment ring using a separating disk and break it at the predetermined breaking point Rough divestment is carried out with glass polishing beads at 4 bar (60 psi) pressure until the objects are visible 28 Fine divestment is carried out with glass polishing beads at 2 bar (30 psi) pressure. Divested IPS e.max Press objects with light reaction layer. 29 Removing the reaction layer After fine divestment, the reaction layer formed during the press procedure is removed using IPS e.max Press Invex Liquid followed by blasting. The procedure is carried out as follows: – Pour the Invex Liquid into a plastic cup. – Immerse the pressed objects into the Invex Liquid and clean in an ultrasonic cleaner for at least 10 minutes and a maximum of 30 minutes. Make sure that the objects are completely covered with Invex Liquid. – Subsequently clean the object under running water and blow dry. – Carefully remove the white reaction layer using Al2O3 Type 100 at 1–2 bar (15–30 psi) pressure. – Make sure that the reaction layer is completely removed, both on the cavity side and on the outer side of the object (repeat the procedure, if necessary). – If the reaction layer is not entirely removed, bubbles may develop, which may lead to bonding problems or even cracks in the layering ceramic. – Replace the Invex Liquid after approximately 20 uses or after sedimentation of the liquid. Remove the reaction layer formed on the pressed objects using the Invex Liquid in an ultrasonic bath. Completely remove the reaction layer from the contact surfaces using Al2O3 at 1–2 bar (15–30 psi) pressure. Warnings – The Invex Liquid contains < 1 % hydrofluoric acid. – It is harmful when inhaled, swallowed, and when it comes into contact with the skin. Furthermore, it is corrosive. – Keep the container tightly sealed and store it in a well-ventilated place (acid cabinet). – If the material comes into contact with the eyes, immediately rinse with copious amounts of water and see a physician immediately. – If the material comes into contact with the skin, immediately clean with soap and copious amounts of water. – Use suitable protective clothing, gloves, and goggles when working. – In case of an accident or physical discomfort, see a physician immediately (bring the Invex label, if possible). Disposal – Neutralize the Invex Liquid – Neutralize the diluted solution by adding lime or baking soda and letting it react for 5 minutes. – After the reaction time, pour the neutralized solution into the sink, flushing it with running water. 30 Finishing It is of critical importance to use the correct grinding instruments for finishing and adjusting glass-ceramics. If unsuitable grinding instruments are used chipping of the edges and local overheating may occur (please see the corresponding recommendations from Ivoclar Vivadent). The following procedure is recommended to finish IPS e.max Press frameworks: – Even though adjustment by grinding of pressed IPS e.max Press frameworks is possible, it should be kept to a minimum. – Wet the area to be ground and use a fine diamond disk to cut the sprues. – Prevent overheating of the ceramic material. Low speed and light pressure is recommended. Please observe the corresponding instructions of the manufacturer. – Smooth out the attachment points of the sprues. – Remove the spacer prior to placing the pressed object on the die. Place the framework on the die and carefully adjust. – Do not 'post-separate' the bridge framework using separating disks, since this may result in undesired predetermined breaking points, which will subsequently compromise the stability of the all-ceramic restoration. – Make sure that the minimum thicknesses are maintained even after finishing. – Blast the framework with Al2O3 at 1 bar (15 psi) and clean it under running water or with steam before applying the veneering material. – Some blasting machines may require different pressure settings to accomplish this procedure. Cut the sprues using a fine diamond disk and place the framework on the die. After adjustment, an excellent accuracy of fit can be achieved. Finish surfaces and smooth out the attachment points of the sprues using low speed and limited pressure. 31 Die fabrication with IPS Natural Die Material The light-curing IPS Natural Die Material simulates the shade of the prepared tooth. A control die is fabricated using the shade information provided by the dentist (shade determination). This control die represents the optimum basis for a true-to-nature shade reproduction of the given oral situation. – Coat the inner surfaces of the ceramic restorations with IPS Natural Die Material Separator and allow it to react for a short time. – Apply die IPS Natural Die Material in the corresponding shade to the inner surfaces of the restoration using the IPS Condenser and adapt so that the entire inner surface is coated and filled. – Completely fill the restoration cavity and insert an IPS Die Holder into the material and adapt excess material around the holder. Make sure that the Die Material is well adapted to the restoration margins and that no gaps are present. – Polymerize the IPS Natural Die Material die with a commercial polymerization light, e.g. Lumamat 100, for 60 seconds. – After polymerization, the die can be finished and or smoothed, if required. Coat the inner surfaces of the ceramic restoration with IPS Natural Die Material Separator and allow it to react for a short time. Completely fill the restoration cavity and insert an IPS Die Holder into the material and adapt excess material around the holder. Then, polymerize with a commercial polymerization light. A die made of IPS Natural Die Material is the optimum basis for true-to-nature all-ceramic restorations. 32 Blast the framework with Al2O3 at 1 bar (15 psi) and clean it under running water or with steam before applying the veneering material. Veneering with IPS e.max Ceram The following paragraphs will explain the most important veneering steps. Detailed information about the nano-fluorapatite ceramic and its processing are contained in the IPS e.max Ceram Instructions for Use. Firing tray and pins Use a honey-combed firing tray and the corresponding support pins to fire the restorations (do not use ceramic pins). Round the top edges of the support pin to prevent the object from sticking to the pin. Another method of reducing this risk is to cover the pins with platinum foil or a small amount of IPS Object Fix. Regularly clean the support pins. Do not use contaminated pins. 33 Wash firing (foundation firing) The framework must be free of dirt and grease before the wash firing is done. Any contamination of the framework after cleaning must be prevented. Wash firing (foundation) is carried out with Deep Dentin, Dentin or Shade and Essence materials (ZirLiner may not be used. Because of its firing temperature of 960 °C/1760°F it only works on zirconium oxide). Variant A: Powder Variant B: Paste With ideal space, conduct the wash firing (foundation) with the required Dentin or Deep Dentin material. Use the IPS e.max Ceram Build-Up Liquids (allround or soft) to mix the materials. If a more plastic consistency is desired, IPS e.max Ceram Glaze and Stain Liquids (allround and longlife) can be used. Apply the wash in a thin coat on the entire framework. With limited space or to increase the in-depth chroma, the wash firing can be conducted using IPS e.max Ceram Shades and Essence. Mix the paste or powder with the IPS e.max Ceram Glaze and Stain Liquids (allround and longlife) to the desired consistency. Apply the wash in a thin coat on the entire framework.
