As restaurações indiretas são comumentes fabricadas em laboratórios de prótese especializados requerendo mais etapas, pois estes usualmente dependem um técnico calibrado com experiência e habilidade, além receberem vários trabalhos diferentes dentistas. E como resposta à dependência cirurgiões-dentistas relação aos prótese, ocorreu o surgimento da tecnologia CAD/CAM (Computer-Aided Design/Compu...

Whether a direct or indirect approach is taken when faced with a patient requiring restorative treatment, creating and designing natural occlusal surfaces is not only a challenge, but also important to achieve proper bite registration, occlusion, and masticatory function. The indirect restoration described in this article features a computer-aided design/computer-aided manufacture (CAD/CAM)-gen...

OBJECTIVE The aim of this multicenter randomized controlled clinical trial was to test posterior zirconia-ceramic fixed dental prostheses (FDPs) veneered with a computer-aided design/computer- assisted manufacture (CAD/CAM) lithium disilicate veneering ceramic (CAD-on) and manually layered zirconia veneering ceramic with respect to survival of the FDPs, and technical and biologic outcomes. ME...

This study aimed to investigate the transfer accuracy (trueness and precision) of three different intraoral scanning families using hardware software versions over last decade from 2012 2021, compared a conventional impression. Therefore, an implant master model with reference cube was digitized served as dataset. Digital impressions all (True definition, TRIOS, CEREC) were recorded (n = 10 per...

There is an increasing interest in “digital” restorative dentistry with the recent introduction of new scanning devices for the fabrication of chairside and off-site restorations. The chairside model-free/ impression-free systems include CEREC® (Sirona Dental Systems, Charlotte, NC) and the newly introduced E4D (D4D Technologies, LLC, Richardson, TX). These two technologies allow the clinician ...

Objective: to evaluate the impact of three different scan strategies and implant angulation on impression accuracyof an intraoral scanner for full-arch multiple scan. Material Method: A maxillary edentulous modelwith six analogs served as a reference model. The four anterior were positioned parallel toeach other, distal right left was placed with 15o 20o, respectively. Thirtyimpression performe...

Three-dimensional scanning of the mouth is required in a large number of procedures in dentistry such as restorative dentistry and orthodontics [1,2]. The 1980s saw the introduction of the first digital intraoral scanner for dentistry by a Swiss dentist, Dr. Werner Mörmann, and an Italian electrical engineer, Marco Brandestini. Nowadays, ten intra-oral scanning devices for restorative dentistry...

BACKGROUND Specimen preparation for in vitro study suffers a general lack of methodological homogeneity, as well as a lack of uniformity in the materials selected for fabricating them. This situation prevents comparisons between studies. When a specimen is not of dental origin it is not possible to study adhesion or bonding techniques realistically. The objective is to design and implement a me...
