Sabino, Tatiana de Andrade; da Silva-Concílio, Laís Regiane; Neves, Ana Christina Elias Claro; Claro, Ana Paula Rosifini Alves [UNESP]; Amaral, MarinaMade available in DSpace on 2022-04-29T08:28:36Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; Aim: In dental implant treatment, there is a demand for mechanically stronger implants. Despite the existence of several studies showing the clinical success of narrow diameter implants, most of them are based on pure titanium (cpTi) alloys. There is a few clinical evidences of the success rate of titan...
Sorption and solubility of bioceramic endodontic sealers and sealer based on ep...
Bastos , Lucas Adriano Pascuti; Vitti, Rafael Pino; Casonato Junior, HomeroIntroduction: Endodontic cements are used in root canal filling and are associated with successful endodontic treatment, filling the spaces between the walls of the root canal and gutta-percha. The sorption and solubility of these materials are properties that are related to the process of remineralization of periapical tissues and antimicrobial capacity, in addition to being parameters linked to deleterious ef...
Stresses in lithium disilicate crowns and zirconia implants in patients with br...
Patricio, Marina Denardi; Caldas, Ricardo Armini; Miranda, Milton Edson; Olivieri, Karina Andrea Novaes; Brandt, Willian Cunha; Vitti, Rafael PinoThe aim of this study was to analyze by finite element analysis the influence of the use occlusal splints in rehabilitation with zirconia implant under oblique and vertical masticatory loads. Four models were developed to simulate a clinical of absence of a premolar (element 45) replaced by zirconia implant and lithium disilicate crown. Four groups were created, SP-V without occlusal splint and vertical load; C...
