background and aims. the aim of this study was to determine the stress patterns within an implant and the effect of different types of connections on load transfer. materials and methods. three different types of implant-abutment connections were selected for this study. sample a: 1.5-mm deep internal hex corresponding to a lead-in bevel; sample b: a tri-channel internal connection; and sample ...

The Brånemark dental implant has undergone progressive development in terms of both the implant body itself and the components connecting the implant to the prosthesis. Many screw and abutment designs have been developed, with various degrees of success. About 15 years ago, CAD (computer-assisted design)-CAM (computer-assisted manufacture) technology was introduced to dentists. More recently CA...

In this paper, the use of geotechnical centrifuge and numerical modeling techniques to investigate influence geogrid reinforcement EPS interlayer on lateral earth pressure backfill surface settlements behind gravity abutment pile-supported is reported. According principle equal strain, back structure, foundation, material, grid material were simulated, centrifugal model test for two types abutm...

This study evaluated experimental abutment forms utilizing adhesion for clinical treatment by the three-dimensional finite element method. Three experimental abutment forms with no axial wall were evaluated: Form 1 was the occlusal surface reduced by 1.5 mm, Forms 2 and 3 were the crown cut perpendicular to the tooth axis 2 mm or 4 mm from the central groove. The restorations were made of 3 typ...

PURPOSE The aim of this clinical research on implant-supported restorations is to analyze, through spectrophotometric digital technology, the influence of the abutment material on the color of the peri-implant soft tissue. MATERIAL AND METHODS Twenty patients received an endosseous dental implant in the anterior maxilla. At the time of each definitive prosthesis delivery, an all-ceramic crown...
