2 GC LAB INFO SHEET 1.14 GC Initial LP NF Compatibility on competitive ceramic systems (CAD/CAM blocks) Test: application of GC Initial LP NF on different competitive ceramic systems (CAD/CAM blocks), milled in the Sirona CEREC MC XL milling machine For each competitive ceramic material an adapted firing schedule should be applied Criteria: Optical appearance SEM pictures Tested Material: Mark II (VITA) Celtra Duo (DENTSPLY) Empress CAD (IVOCLAR) Cerec Blocs C In (SIRONA) Suprinity (VITA) e.max CAD (IVOCLAR) Test procedure: Out of all above mentioned competitive blocks 6 crowns were milled in the Sirona CEREC MC XL milling machine. Processing: After milling, the connection parts are cut and the crowns are carefully cleaned. LP NF application: LP NF is applied following the GC Initial LP NF instruction for use. Important: Combined crystallization and stain firings using GC Initial LP NF are not possible for e.max CAD and Suprinity. Both competitors have their own stain system in their product portfolio.

The temperatures have to be adjusted to the furnace you are using and according to the result after firing. Always make sure your furnace is correctly callibrated. Conclusion: AFTER the required crystallization firing (according to each manufacturer s instruction for use) our above recommended firing schedule can be used without any problem for glazing the tested ceramic materials. ONLY crystallized material can be glazed. A combined firing (crystallization firing / glaze firing) is not possible. All conclusions are based on internal fabricated samples and measurements.

4 GC LAB INFO SHEET 2.14 Use of GC Initial MC Paste Opaque CL on NP-alloys Tips & Tricks Non-precious frameworks should be sandblasted with Aluminum Oxide > 110μ, even better 250μ and with 3-4 bar of pressure. Use dental non precious metal substructures with a coefficient of thermal expansion in the range of 13,8-14, K-1 ( C). Whether you first applied INmetalbond (recommended see dedicated IFU) or directly the Paste Opaque onto the metal structure, you always should follow the following steps: Frame with applied opaque Apply a thin layer of Opaque (semi-masking/wash type) evenly to the coping or bridge framework. Please use a Paste Opaque brush. The Paste Opaques (no matter which) must first be rubbed into the rough surface followed by application of a Wash Opaque layer and then fired. The intention is to obtain a good wetting with the Opaques. If Opaques are applied to fast, a good surface wetting is not obtained which may result into bubbles and lead to poor adhesion values. Ensure that this first layer is not too thick. If a too thick layer of Paste Opaque is applied, uncontrollable amounts of liquid evaporate during the heating stage and can cause the occurrence of bubbles. Opaque surface after 1st bake After the Wash Opaque bake is finalized, the second Opaque bake is carried out. Please refer to the firing temperatures and times. Do not dry the Paste Opaque too quickly. If the recommended preheating and firing times are not followed, small cavities can open up at the surface or the Opaque may lift off from the substructure. This happens if the Opaque liquid evaporates too quickly by an improper or accelerated firing schedule! Opaque surface after 2nd bake GC Lab Info Sheet 2.14

The temperatures have to be adjusted to the furnace you are using and according to the result after firing. Always make sure your furnace is correctly calibrated. Important note: * In case non-precious alloys are used without INmetalbond, the firing temperatures of the Wash Opaque firing should be increased with 20 C. This is not applicable in case INmetalbond is applied. GC Lab Info Sheet 2.14

6 GC LAB INFO SHEET 2.14 General recommendations for GC Initial MC Oxide firing: Oxidation-firing of non-precious alloys not always obligatory indicated (not a must ). From the chemical point of view it is also highly recommended to remove the excess of oxides. Because the oxides on the top area of the alloy are necessary for bonding but too much of them on the surface is contraindicated. Also from an esthetical point of view oxides need to be removed. Sandblasting: Sandblast 110µ-250µ with 3-4bar and try to directly apply the Opaquer or Bonder (in the next 10 minutes) after sandblasting and cleaning of the framework. During sandblasting a kind of electrostatic charge/activity is generated resulting in a better adaptation/wettability of Bonder/Opaque. Application of Bonder/Opaquer: Please use a Paste Opaque brush. The Paste Opaques (no matter which) must first be rubbed into the rough surface followed by application of a Wash Opaque layer and then fired. The intention is to obtain a good wetting with the Opaques. The rubb effect allows the Opaque to flow into the small retentions created by the sandblasting. Simply brushing the Opaque is not optimal as this might cause lifting off of the Opaque and therefore only sinter on top of the alloy. Otherwise a good surface wetting will not be achieved resulting into bubbles and reduction of adhesion values. Ensure that this first layer is not too thick. A too thick layer of Paste Opaque can lead to uncontrollable amounts of liquid evaporating during the heating stage and causing the occurrence of bubbles. Conclusion: Precious/Semi-Precious alloys always have to be sandblasted- >oxidized->sandblasted NPA have to be sandblasted. If they will be oxidized (for visual check) they have to be sandblasted again after oxidation. Allays carefully read recommendations of the alloy s manufacturer. GC Lab Info Sheet 2.14

Latest results confirm that, especially zirconium dioxide must be veneered with great care. As described in the literature, the poor thermal conductivity of zirconium dioxide, can lead to greater residual stresses within the bonding system framework/ceramic, similar to metal ceramic sytems. Especially with massive frameworks, the thermal residual stresses can be tempered by slowly heating up and a controlled long-term cooling of the restoration to a temperature of 450 C. Due to the slow heating and individually extended holding time also the uniform sintering of the veneering ceramic is guaranteed also on massive pontics. The well-known guidelines for all-ceramic restorations must of course continue to be respected. Following the above information, the below firing procedure are recommended in order to achieve an even higher level of security.

Based on the used ceramic furnace, the firing trays, the positioning of the restoration in the firing chambre, differences may arise and parameters have to be adapted accordingly. This is crucial for obtaining the best firing result GC Lab Info Sheet 2.15

11 GC LAB INFO SHEET 3.15 GC Initial LiSi Shade Guide Generally speaking only a small amount of powders is used for veneering Lithium Discilicate frameworks (cfr. IFU e.max Ivoclar). Therefore we have choosen to have a slightly increased chromatic intensity of our LiSi Dentin powders. In order to have the best judgement on the reality of the colours, we have choosen to create Dentin tabs made from original LiSi Dentin powders. In order to well differentiate the LiSi Dentins from the other ceramic systems we offer, we made a small identification in the form of a small retention on the plastic holder of the shade tab. The Shade Guide consists of 3 CD s in total and can be ordered via article number Unlike the other GC Initial shade guides they are not part of the set in order to reduce the cost of the set. They are replaced by a colour printed GC Initial LiSi Colour Chart. GC Lab Info Sheet 3.15

12 GC LAB INFO SHEET 4.15 GC Investment Liquid Bottles packaging update Following production improvement projects regarding quality and cost reduction it has been decided to create conformity within the Investment Liquid Bottles. Implemented changes: - Only one type of plastic bottle and cap: o New plastic bottle with separate identification sticker for each investment o White cap for all bottles - Conformity of labels following European CLP regulation Due to these changes a significant cost reduction and quality improvement has been implemented. We avoid differences in printed bottles, quality issues due to coloured plastic caps and simplify our stock level of packaging material. GC Lab Info Sheet 4.15

13 GC LAB INFO SHEET 1.16 WEAR RESISTANCE OF NEW INDIRECT COMPOSITE Study by H. Kato, D. Machida, T. Ueno, T. Kumagai (Research & Development Department, GC Corp., Tokyo, Japan) Presentaed during EPA: European Prosthodontic Association, Halle, Germany, 2016, 9/ Abstract A new indirect composite system has been developed: GRADIA PLUS LB (Light Body, flowable type) / HB (Heavy Body, paste type) (Fig. 1). GRADIA PLUS overcomes weaknesses of Micro-Filled Resin (MFR) by adopting nano-filler technology, the same as G-aenial Universal Flo (GC) and CERASMART (GC). All demonstrate with high gloss retention and high mechanical properties. 2. Study purpose Evaluate the wear resistance of GRADIA PLUS and other indirect composites against enamal antagonist after three body wear test. 3.

15 GC LAB INFO SHEET Results & Discussion Fig. 3 Wear value of composite specimen (a), and bovine enamel antagonist (b) Same superscript indicates no statistically difference. GPL and GPH exhibited significantly lower wear value of specimen (Fig.3a) and bovine enamel antagonist (Fig.3b) compared to the other indirect composite before and after thermal cycling. Wear surface of GPL and GPH were smooth after thermal cycling and wear test. Page 3 GC Lab Info Sheet 1.16

16 GC LAB INFO SHEET 1.16 Fig. 4 Wear surface of indirect composite specimens after thermal cycling and three body wear test In contrast, CLF, CLP and NP had totally damaged and cracked wear surface (Fig. 4) Glass filler size of GPL and GPH is ultra fine. However GR, CRM and SC contain micro size glass filler (Table1), and CLF,CLP and NP contain larger pre-polymerized filler. This may indicate that these larger filler is caused higher wear value of enamel antagonist. This may indicate that these larger filler is caused higher wear value of enamel antagonist. In addition, pre-polymerized filler Is difficult to be treated by a silane coupling agent due to lower filler content. Therefore crack was generated from interface between pre-polymerized filler and resin matrix by stress of expansion/contraction of filler during thermal cycling in CLF,CLP and NP. However, GPL and GPH were not much affected by thermal cycling, due to ultra fine filler of these products was most suitably treated by a silane coupling agent. 6. Conclusion GRADIA PLUS LB and HB had higher wear resistance and lower wear value of enamel antagonist due to ultra fine filler content and most suitable treatment for filler by a silane coupling agent. GRADIA PLUS should lead to clinical longevity. Page 4 GC Lab Info Sheet 1.16

17 GC LAB INFO SHEET 2.16 Notchless triangular prism fracture toughness of new indirect composite Study by H. Kato, D. Machida, T. Ueno, T. Kumagai (Research & Development Department, GC Corp., Tokyo, Japan) Presented during EPA: European Prosthodontic Association, Halle, Germany, 2016, 9/ Abstract A new indirect composite system has been developed: GRADIA PLUS LB (Light Body, flowable type) / HB (Heavy Body, paste type) (Fig. 1). GRADIA PLUS overcomes weaknesses of Micro-Filled Resin (MFR) by adopting nano-filler technology, the same as G-aenial Universal Flo (GC) and CERASMART (GC). All demonstrate with high gloss retention and high mechanical properties. Fracture toughness of dental materials is evaluated as a method to measure a resistance level of the destruction. Notchless triangular prism (NTP) fracture toughness test has been paid attention as an effective method for measuring fracture toughness of composite resin. 2. Study purpose Evaluate the NTP fracture toughness of GRADIA PLUS and other indirect composite. 3.

Products which exhibited high flexural strength and high flexural strength tended to exhibit high NTP fracture toughness (Fig. 5). GR, SC, CLF, CLP and NP which contained pre-polymerized filler (Fig.3, Table2) exhibited lower NTP fracture toughness and flexural strength. Pre- polymerized filler is difficult to be treated by a silane coupling agent due to lower filler content, so it causes low cohesion between pre-polymerized filler and resin matrix. GPL and GPH contain polyfuntional monomer and are filled ultra fine filler at high density which is most suitably treated by a silane coupling agent. Polyfunctional monomer forms a complicated network by polymerization and abundant ultra fine filler raise strength of composite resin more. Therefore, GPL and GPH exhibited higher properties.

Conclusion New indirect composite, GRADIA PLUS LB and HB, exhibited higher NTP fracture toughness than the other indirect composite resin, and it may suggest that GRADIA PLUS is not easily fractured in clinical use.
