Influence of Ceramic Materials on Biomechanical Behavior of Implant Supported Fixed Prosthesis with Hybrid Abutment
(2019-05-30)
PURPOSE: This study evaluated the stress distribution in different cement-retained implant-supported prostheses with a hybrid abutment. MATERIALS AND METHODS: Two factors were evaluated: restorative material for the crown ...
Effect of Abutment Screw Surface Treatment on Reliability of Implant-Supported Crowns
(Quintessence Publishing Co Inc, 2014-05-01)
Purpose: To evaluate and compare the reliability of implant-supported single crowns cemented onto abutments retained with coated (C) or noncoated (NC) screws and onto platform-switched abutments with coated screws. Materials ...
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 ...

Stress analysis of axial and tilted implants in full-arch fixed dentures under different abutment conditions
(2016-01-01)
The aim of this study was to evaluate the stress distribution on fullarch prostheses, considering axial implants and tilted implants with or without abutments. Two photoelastic models were made, being that in 1 model the ...
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, ...

(2014-01-01)
Purpose: To evaluate and compare the reliability of implant-supported single crownsabutments retained with coated (C) or noncoated (NC) screws and onto platform-switched abutments with coated screws. Materials and Methods: ...
Bacterial leakage along the implant-abutment interface of premachined or cast components
(CHURCHILL LIVINGSTONE, 2008)
In recent clinical studies, contamination of the inner parts of dental implants through bacterial penetration along the implant components has been observed. The aim of the present in-vitro study was to investigate leakage ...
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 ...
Fracture of Zirconia Abutment with Metallic Insertion on Anterior Single Titanium Implant with Internal Hexagon: Retrieval Analysis of a Failure
(Dennis Barber Ltd, 2016-09-01)
This case report presents a retrieval analysis of a screw-retained one-piece restoration with the veneering ceramic fired directly onto the zirconia abutment that fractured during insertion. A patient who experienced root ...
