“…25 Blue is required more to achieve lighter skin tone while yellow is required more for moderate to substantial color matching with the skin. 48 While the current study focused on the stability of basic colors individually; clinically, the colors are mixed together with silicone elastomer based on patient specific needs and clinical judgment. Therefore, the amount mixed will always be a subject of variation.…”

Purpose: This systematic review and meta-analysis explored the factors involved in the color stability and degradation of Maxillo-Facial Prosthetic Silicone Elastomer (MFPSE). Further exploration was done to analyze past literature discussing the potential benefits to color stability when nano-particles were combined with pigmented MFPSE. Method: The search for the articles was done according to PRISMA guidelines. Articles were searched from “Scopus” and “Web of Sciences” from the year 1970 to 2019. Searches were carried out by two reviewers until November 2019. Articles for systematic review were selected based on predefined eligibility criteria. Information regarding weathering conditions, pigments and filler-particle inclusion were extracted as appropriate. Further screening was done for meta-analyze case-control studies of red, blue and yellow pigments according to predefined scoring criteria. Meta-analysis was conducted on case-control studies that incorporated 5%,10% and 15% TiO2 in MFPSE with the said pigments and was carried out using Cochrane Review Manager 5.3. Results: 30 studies were selected for systematic review and 6 studies were eligible for meta-analysis. The most prominent influencers of color stability were nano-fillers and the type of color used in the mixing. Furthermore, experimental conditions, weathering, color of investment plaster and the method of color detection all affected the degree of degradation. There was an overall significant difference found when TiO2 was incorporated with the pigmented silicone. There is significant difference when 10% ( P = 0.0004) TiO2 is incorporated with the red pigment, 5% ( P = 0.03) TiO2 with the yellow and 10% ( P < 0.0001) and 15% ( P = 0.02) TiO2 with the blue pigment. Conclusion: Type of pigment and nano-filler incorporated into the silicone play a role in influencing color stability. Incorporation of 10% TiO2 with red pigment,5% with yellow pigment and 10% or 15% TiO2 with blue pigment provided some protection to the silicone elastomer from color degradation.

“…Several techniques have been proposed to mitigate these challenges such as producing prefabricated shade guides or utilizing a colorimeter for production of an intrinsic tone. These solutions do not address differences in material thickness and their effect on the appearance of the material 5,6 . Over et al.…”

Shade matching of extraoral prostheses is completed by mixing pigments and rayon flocking into medical‐grade silicone and using a carrier to evaluate the color match. This process does not account for how material thickness affects the appearance of the silicone. This clinical case report discusses an innovative way to match the patient's skin tone using a digitally designed gradated silicone carrier and how this device allows for the assessment of shade from the thin marginal edge to 5 mm thickness.

“…Surface characteristics, for example, hairline fractures and hypocalcifications, are marked on the chart and sent to the lab together with a digital image. The image should show the selected shade tab beside, ideally in the same vertical plane as the prepared tooth (Figure 1) and the adjacent teeth to help the dental technician to produce the shade properly 23 …”

“…The image should show the selected shade tab beside, ideally in the same vertical plane as the prepared tooth (Figure 1) and the adjacent teeth to help the dental technician to produce the shade properly. 23 A digital approach to solve the difficulty of shade selection is to use a clinical color measuring device. It is reported that these devices' reliability is 90%, and their accuracy is from 60% to 90%, yet still, some show clinical results similar to visual shade matching.…”

ObjectivesAlthough the presence of a chairside CAD/CAM system in the dental office saves time and cost, it deprives the dentist from the dental technologist' skills and experience. The dentist now has to gain and acquire knowledge and skills about how to finish, characterize, stain, and glaze ceramic restorations. The main objectives of this article is to teach novel and reproducible techniques for surface color, texture, glaze and polish for either the chairside or laboratory fabricated indirect ceramic restoration.Clinical ConsiderationsA protocol for intraoral characterization of monolithic ceramics; the “Triple R" protocol for tooth color mimicking was followed. It consist of three steps: (1) “Recognize” tooth color shapes, (2) “Record” the present color shapes in the patient dentition by drawing a color map for the color shapes extension and determine which luster paste stain to be used for replicating them, and (3) “Replicate” intraorally the recorded color shapes guided by the adjacent natural teeth using low fusing ceramic pastes (shades and stains) for color shape replication. Also, the final touch technique was followed to shape, texture and final surface finish of dental restorations. It is composed of 5 basic levels which we call dental “micro‐esthetics that define shape, texture, and surface luster.ConclusionsFollowing the steps of both; the “Triple R” protocol and the “FINAL TOUCH” technique will help to reproduce the final shade of the restoration to create the illusion of a natural tooth to the observer.Clinical SignificanceThis article shows how combining two practical methodologies to record and replicate both color shapes and surface texture of natural teeth may extend mimicking, that is, step by step natural tooth shade beyond the limitations of the available commercial shade guides.
