Performance of different abutment/implant joints as a result of a sealing agent
(2021-01-01)
Purpose: This in vitro study aimed to evaluate the effectiveness of a sealing agent in sealing the abutment/implant interface and the preload maintenance of retaining screws after mechanical cycling. Methods: Six groups ...
Comparison of the Morse Cone Connection with the Internal Hexagon and External Hexagon Connections Based on Microleakage - Review
(2021-01-01)
The gap formed at the abutment-implant interface brings about a bacterial colonization. In addition, a bacterial reservoir can be established within the implant. The build-up of microorganisms around the implant can cause ...
Mechanical analysis of conventional and small diameter conical implant abutments
(KOREAN ACAD PROSTHODONTICSSEOUL, 2013-08-02)
PURPOSE. The aim of the present study was to evaluate if a smaller morse taper abutment has a negative effect on the fracture resistance of implant-abutment connections under oblique compressive loads compared to a ...
Avaliação da interface de cinco sistemas de implantes e seus respectivos abutments com auxílio do método de microscopia eletrônica de varredura

Stress distribution in implant-supported prosthesis with external and internal implant-abutment connections
(2013-03-01)
Objective. This study aimed to investigate the stress distribution in screwed implant-supported prostheses with different implant-abutment connections by using a photoelastic analysis. Materials and methods. Four photoelastic ...

FEA and microstructure characterization of a one-piece Y-TZP abutment
(Elsevier B.V., 2014-11-01)
Objectives. The most important drawback of dental implant/abutment assemblies is the need for a fixing screw. This study aimed to develop an esthetic one-piece Y-TZP abutment to suppress the use of the screw.Methods. ...
Failure modes of Y-TZP abutments with external hex implant-abutment connection determined by fractographic analysis
(2016-07-01)
Yttria-stabilized tetragonal zirconia (Y-TZP) was introduced as ceramic implant abutments due to its excellent mechanical properties. However, the damage patterns for Y-TZP abutments are limited in the literature. Fractographic ...
Implications of Surface and Bulk Properties of Abutment Implants and Their Degradation in the Health of Periodontal Tissue
(Mdpi Ag, 2013-12-01)
The aim of the current review was to investigate the implications of the surface and bulk properties of abutment implants and their degradation in relation to periodontal health. The success of dental implants is no longer ...
