What is it? Eclipse is a revolutionary new prosthetic resin system. MMA monomer-free and investment-free. The Eclipse System uses three resins to form the denture: Baseplate Resin Set-up Resin Contour Resin. The resins were developed to handle like wax, yet be cured into a denture base material without investing and flasking. The baseplate used at try-in will be incorporated into the denture that will be delivered. The fit at try-in has been shown in a clinical study to equal fit at delivery. What is the benefit of Eclipse to me, the Clinical Professional? The fit at try-in equals the fit at delivery MMA monomer-free Teeth are more stable during try-in and in transit to/from your dental laboratory Is there any reason why I would not want to use an Eclipse denture? Though there are a few slight difference, we designed Eclipse denture base material to stay within the workflow of conventional denture base materials. We feel the superior fit and comfort, MMA monomer-free, and using the final processed baseplate for the occlusal records and try-in, will overshadow any concerns a dentist may have about using Eclipse denture base materials. However, if a patient has a very tight vertical distance, the Clinical Professional may choose to use a conventional material since teeth must have retention grooves ground into them. If a tooth must be ground down to a point where there is no depth remaining to cut retention grooves or a collar groove, then Eclipse may not be suitable. What is the benefit to my patients? The fit at try-in equals the fit at delivery. It ís methyl, ethyl and butyl methacrylate free. Was the material clinically tested? Yes. A multi-site clinical study was conducted to make sure the product is efficacious and performs well. Additionally, Eclipse has been proven safe. Eclipse materials have been thoroughly tested and comply with FDA requirements, ISO 10993 guidelines, and International Standard ISO 7045. The toxicological/biocompatibility test matrix includes cytotoxicity, genotoxicity (Ames), sensitization, irritation, and oral toxicity evaluations. What is the difference between Eclipse and Triad Denture Base Material? Eclipse materials use a different chemistry. Eclipse is stronger than Triad. With Eclipse, the three different resins are combined to create the denture. Eclipse is wax-like, tried in like a wax try-in, and then cured; Triad is not. Eclipse is carvable and can be tried-in; Triad can not. Eclipse is shaded like L199; Triad is not. What is the difference between Eclipse and Lucitone 199? Eclipse handles like a wax; L199 does not. Eclipse is MMA monomer-free; L199 is not. Eclipse does not require investing or boiling out; L199 does. With Eclipse, fit at try-in equals fit at delivery. This claim can not be made with L199 unless a processed baseplate is used, which is rarely done due to the extra labor required. Eclipse has about a 3% volumetric shrinkage while conventional acrylics and L199 are about 7%. Eclipse requires mechanical retention between the resins and the teeth; L199 does not (but a high percentage of laboratories use mechanical retention with conventional denture resins). Before requesting an Eclipse denture, is there anything I need to purchase? The Clinical Professional may need a warm water bath to soften the resins to adjust teeth, or silicone based materials to take a new bite registration (DENTSPLY Caulk Regisil ® and to "plump" the gingival areas(DENTSPLY Caulk Reprosil ® . Other than that, there is no equipment to be purchased. If I pour my own models, do I need to do anything special? If you pour your own models and send them to the laboratory, you need to make sure that the land areas are no greater than 1mm above the depth of the sulcus to allow light penetration for complete curing of the border areas. Carve the postñdam in the master model if not included in the impression. Which materials are available in clear? The upper and lower baseplates are available in clear, perfect for nightguards and occlusal splints. Can the clear material be used to fabricate a clear baseplate, or a baseplate with a clear palate? Yes, though we anticipate the clear material being used primarily for nightguards and occlusal splints. Do the materials bond well together? Is there any problem with the layering? The Baseplate, Set-up and Contour Resins all bond well together. Eclipse appliances may also be relined with various materials that you are accustomed to working with, such as DENTSPLY Austenal PermaSoft. Can Eclipse be used with both acrylic and porcelain teeth? Yes. You can choose acrylic or porcelain teeth for your cases. However, since there is no chemical bond between the tooth material and the Eclipse materials, mechanical retention is necessary. How are the teeth retained in the denture? The teeth must have retention groves cut into them. Teeth will not adhere to the material without mechanical retention. What about displacement of the teeth at try-in? Eclipse is more stable than wax. Teeth will not move unless the dentist warms the material in a warm water bath to adjust them, or the patient uses excessive biting force. Is there any staining at the gingival margin of the tooth, similar to porcelain teeth? A clinical study has not demonstrated any gingival staining. At the occlusal records appointment, do I need to do anything special? As with all dentures, the accuracy of the records is reflected in the try-in and final dentures. As always, make sure to: Indicate the inter occlusal distance between the upper and lower arch, the mid-line between the two maxillary centrals, and the width of the anterior six. If I want to plump or reduce the gingival areas at try-in, how should this be done? To plump, use silicone putty, such as DENTSPLY Caulk Reprosil, to add volume to the gingival area. Do not use wax. To reduce, just carve material away, or instruct your laboratory to do so. How do I take a bite registration with this material? If you need to re-take the bite registration, use silicone based material, such as DENTSPLY Caulk Regisil, and proceed as usual. Do not use wax. Can I take a wash impression if needed? Yes. If necessary, take the wash impression at the occlusal appointment, not at the try-in appointment. Any changes should be made as early in the process as possible. Why is the try-in returned in a light-safe bag? The material has a degree of light sensitivity. Having the appliance in ambient light while you are working with your patient is not a problem. Otherwise, keep the appliance in the light-safe bag. Is it possible to make in-office adjustments and move the teeth at try-in? Yes. If the teeth need minor adjustments, you can do this chairside by preparing a water bath at 110†F (43†C). Then place the set-up into the water for approximately 30-45 seconds to warm the uncured denture base material and move the teeth. When moving the teeth, warm the resin and push on the Contour Resin near the base of the tooth to move it into position. Do not push directly on the tooth as a gap or void may be created that can impact tooth retention. The Chairside Aid explains this, as well as the Clinical Procedures CD. If the occlusion is not acceptable at try-in can the teeth be removed for a new bite registration? Yes. Use a silicone material, such as DENTSPLY Caulk Regisil, to make a new bite registration. Do not use wax. Can I reposition the midline chairside? If moving the teeth more than 1mm, send the case back to your dental laboratory for a reset. I use alcohol-based disinfectants at try-in; will this have an adverse effect on this material? On cured dentures, all common disinfectants (including phenolics) work. However, on uncured resins, do NOT use phenolic or ethyl alcohol based disinfectants. (e.g. BIREX by Bitrol International and ProPheneTM plus by Cottrell.) Disinfecting products such as Banicide and Cavicide work well with uncured Eclipse Dentures. What about displacement of the teeth at try-in? A. Eclipse is more stable than wax. Teeth will not move unless the clinical professional warms the material in a warm water bath to adjust them, or the patient uses excessive biting force. Since Eclipse is 100% MMA monomer-free, can relines and repairs be done on the Eclipse dentures?Other MMA monomer-free materials, such as those used in flexible resin systems, do not reline and repair well. Yes. Eclipse can be relined and repaired just like conventional denture materials. Can I reline in-office? Your Eclipse dentures can be relined in either the office or at the laboratory. Relines can be done with quick curing materials, such as DENTSPLY Austenal PermaSoft reline material, as well as Lucitone 199 Denture Base Material. Can I use Eclipse to repair/reline conventional dentures? Eclipse materials can only be used to reline and repair Eclipse appliances. Though other materials may be used to reline or repair an Eclipse denture, the temperature required to cure Eclipse materials is too high for conventional materials. The conventional materials may warp. Will Eclipse dentures accept soft liners? Cases that have been done have been satisfactory using DENTSPLY Trubyte Luci-Soft silicone soft liners, and DENTSPLY Austenal PermaSoft. Does Eclipse need a bonding agent for repairs and relines? No, not when using Eclipse resins or conventional methylmethacrylate materials. Are Eclipse repairs strong? Other MMA monomer-free materials have proven to break easily in the same location once they are repaired... Yes, Eclipse repairs are strong. Through extensive laboratory testing we have found that Eclipse repairs fail across, and not along, the interface which is a key indication of a durable repair. If an Eclipse denture is broken a second time, the fracture typically does not occur at the repair site, another indication of a robust repair.
