Avaliação da interface de cinco sistemas de implantes e seus respectivos abutments com auxílio do método de microscopia eletrônica de varredura
(Universidade Estadual Paulista (Unesp), 2005)
A adaptação entre a plataforma do implante e seu respectivo abutment deve ser precisa, isto é, sem nenhuma fenda, que é denominada microgap, entre as estruturas. A presença do microgap permite que microorganismos presentes ...

Stress distribution around implants with abutments of different materials: A comparison of photoelastic, strain gage and finite element analyses
(2015-01-01)
Objective: To compare stress transmission around implants with abutments made of three different materials using photoelastic, strain gage (SGA) and finite element (FEA) analyses. Methods: Three abutments - UCLA calcinable, ...
Influence of implant connection on the stress distribution in restorations performed with hybrid abutments
(2019-09-01)
Aim This study evaluated the influence of prosthetic connection type (external hexagon [EH], internal hexagon [IH] and morse taper [MT]) on the stress distribution in an implant-supported prosthesis. Materials and methods ...
Detorque evaluation of dental abutment screws after immersion in a fluoridated artificial saliva solution
(WileyPhiladelphia, 2013-06)
Purpose: Implant-abutment connections still present failures in the oral cavity due to the loosening of mechanical integrity by detorque and corrosion of the abutment screws. The objective of this study was to evaluate the ...
Deformation of Implant Abutments After Framework Connection Using Strain Gauges
(Allen Press Inc, 2012-04-01)
When a cylinder is connected to an abutment it is expected that abutment and cylinder will be subjected to compression forces throughout their periphery because of the clamping force exerted by the screw. The deformation ...

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 ...
