Levantamento de protocolos adotados por especialistas para restaurações indiretas do tipo coroa total sobre substrato dental em região anterior e posterior

Abstract

The aim of this study was to identify the protocols used for indirect anterior and posterior restorations on dental substrate, used in Dental Prosthesis Specialization Courses and by professionals already specialists in the area. Two groups participated of this study, the first composed of 40 dental surgeons specialized in Dental Prosthesis and the second by 7 Specialization Courses of the same area. Both answered the same questionnaire about ceramic systems and cementation used for unitary indirect restorations of posterior and anterior teeth, on dental substrate in color A2 of the VITA scale (Vita Zahnfabrik). It was observed that among the prosthodontists, the majority (82.5%) opted for lithium disilicate for indirect restorations of anterior teeth and metalloceramics (32.5%) for posterior teeth. Alumina and felspathic were the least used materials in anterior and posterior regions. Dual resin cement was the most used for anterior teeth (57.5%) and posterior teeth (45%). Among the schools of Specialization and Updating courses, lithium disilicate (86%) was the first choice for anterior teeth and, for posterior teeth, zirconia (72%). Regarding cementation, both in the posterior and in the anterior regions, dual resin cement was the most used. From this survey of the protocols used, it was possible to identify that the two realities are similar, especially in the anterior region with preference for lithium disilicate, emphasizing the importance of knowledge of the materials available in the market.
