“…The conservative use of ceramic veneers provides satisfactory aesthetic results, preserving the structure of the teeth [8]. For this purpose, a carefully defined treatment plan and good communication between the dentist and the prosthetic lab help to maximize the success of treatment.…”

“…There are several methods to obtain the necessary reduction as the free hand, which is the use of grooves and silicone guides that allow a visualization of the reduction needed to reach the shape and contours of the preplanned shape [8, 13]. Different models of tooth preparation have been described, differing only in the incisal third, overlap (palatine chamfer), and incisal reduction with the elimination of the palatine chamfer, resulting in stronger restorations and preparation of the simplified tooth [2, 3, 5].…”

“…The ceramic properties, color stability, bond strength, clinical longevity, aesthetics, and biocompatibility with the periodontal tissues make this material a good choice of treatment [1, 3, 5, 8]. Feldspathic ceramics consist, predominantly, of silica powder or quartz, in a ratio of 46–66% aluminum oxide and liquid glass-based materials.…”

Currently, there has been a growing demand for restorations of anterior teeth in the routine of doctors in dental offices. With advances in adhesive technology and good properties of the available ceramics, the use of ceramic veneers has been offered as a treatment option for cases where teeth have minor color changes and shape and position changes. Through careful treatment planning, it is possible to conservatively use ceramic veneers in the treatments, applying techniques with minimal wear of the teeth and obtaining excellent aesthetic results with mechanical stability and biocompatibility with the periodontal tissues and clinical longevity. This clinical case report was used to design the digital smile, which guided the production of the diagnostic waxing of the superior model. Silicone guides were then made to create the mock-up, orienting enamel/dentin wear and assisting the preparation of the crowns with bis-acryl resin. When the wear was finished, the gingival separation was performed using the double-thread technique. In the molding process, the second wire was withdrawn and the molding material flowed into the gingival groove, copying the terminal region. After analysis of the quality of the impression, the temporary crowns were made with bis-acryl resin, using the guide. The color of the cementing agent was chosen using a glycerin-based compound which simulates the final color of the cement. After two hours of drying, two different layers of silane were applied for 60 seconds. After the preparation of the piece, gingival isolation and separation were done. The dental substrate was degreased with detergent solution and conditioned with 37% phosphoric acid for 15 seconds and then washed for 45 seconds for subsequent drying, leaving the substrate moistened. The adhesive system was applied for 30 seconds, waiting for the adhesive to penetrate into the conditioned dentinal tubules. A light air jet was applied, and then each tooth was photopolymerized for 30 seconds. The resin cement was placed inside the pieces and placed in position and photopolymerized. The excess cement was removed; after a layer of glycerin in the cervical region, aiming to block the entry of oxygen and polishing was performed. The purpose of this case report was to describe a sequence of clinical steps, from planning to cementation, in a case of aesthetic correction using feldspathic ceramic veneers.

“…No último caso, especificamente, tornou-se possível indicar, de início facetas de porcelana (Calamia, 1983;Horn, 1983), e hoje fragmentos cerâmicos com pouquíssima espessura, para restauração de dentes, agora com mínimo ou nenhum preparo sequer (Goldstein, 2007;Nosti, 2009;Lowe, 2010;Pini et al, 2012;D'arcangelo et al, 2018). Por meio da cimentação de peças ultrafinas ao esmalte dentário solucionam-se casos de amelogênese imperfeita ou hipoplasia de esmalte, desgaste dentário, diastemas, dentes conóides, dentes pequenos ou girovertidos, dentre inúmeros outros (Della Bona, 2009).…”

Silva JCV. "Traditional" vs. self-limiting phosphoric acid etching for different times on the bond strength of a conventional light-curing resin cement and a self-adhesive dual curing resin cement to bovine enamel [dissertation]. São Paulo: Universidade de São Paulo, Faculdade de Odontologia; 2019. Versão Original.The success of ceramic veneers and pieces depends on a good interaction between the dental substrate and the resin cementing system and its interaction with the restoration, since that, beyond the small dimensions involved, it is not determined, as a rule, any other form of retention of the piece. For this reason, it is important the proper acid etching of the enamel, non or minimally prepared, determining the adhesive interface most susceptible to debonding. Thus, bond strength (BS) of a conventional vs. self-adhesive resin cement to the bovine enamel was evaluated in relation to acid etching (phosphoric) with different attributes and for diverse times of application. Bovine enamel fragments, included in acrylic resin (0.5" PVC cylinders), were planned and subjected to standard smear layer creation (SiC #180 and #600/1 min sandpaper). They were then etched with different acids (EU: Ultraetch ® / CDG: Dental Gel ® Conditioner), for different times (0s -control / c; 15s; 30s; 60s; 120s), and to the construction of microcylinders (7 per tooth; 1 mm in diameter) with one of the resin cements: RV / RelyX Veener ® (previous application of Scotchbond Multipurpose adhesive) or R200 / RelyX U200 ® . After 24h, they were submitted to a microshear test (1 mm/min), evaluating the type of failure with a digital microscope (40X). Regarding as experimental factors the type of cement (in two levels), the acid agent for enamel etching (in two levels) and its the time of action (in four levels), a statistical analysis of the data obtained was performed by means of a 3-way ANOVA analysis and a Tukey test. To compare each of the experimental groups individually and with control groups, Kruskal-Wallis and Tukey tests were used once the distribution was normal (Shapiro-Wilk, p = 0.137) but not homogenous (Equal Variance Test, p < 0.05). In all cases a significance level of 5% was adopted.Regardless of the cement used and its time of application, etching with traditional acid always revealed greater BS values than those with self-limiting acid.Additionally, regardless of the applied acid and of the time of its action, use of the dual self-adhesive always obtained higher values of BS than the light-curing conventional one. Regarding the cement or the acid used, the time of application of the light-curing conventional cement did not exert any significant influence over the results. Comparatively to the non-etching, the one with any of the acids and any of the application time always favored BS of both cements to enamel. At the moment, within the indications of each of the cements and having in mind that the selfadhesive cement can be related to a better adhesion to enamel, as long as associated to previous acid-etching, it see...
