Influence of sealing of the screw access hole on the fracture resistance of implant-supported restorations
(2016-03-01)
The purpose of this study was to assess the influence of sealing of the screw access hole (SAH) on the fracture resistance of metal-ceramic implant-supported restorations. UCLA abutments were used to make 30 implant-retained ...
Evaluation of the Effect of Retightening and Mechanical Cycling on Preload Maintenance of Retention Screws
(Quintessence Publishing Co Inc, 2011-03-01)
Purpose: The aim of this study was to evaluate the effect of retightening and mechanical cycling on the maintenance of preload in the retention screws of implant-supported crowns. Materials and Methods: Five groups (n = ...

(2011-01-01)
Purpose: The aim of this study was to evaluate the effect of retightening and mechanical cycling on the maintenance of preload in the retention screws of implant-supported crowns. Materials and Methods: Five groups (n = ...
Quando e porque utilizar pilares intermediários ou abutments UCLA em próteses aparafusadas sobre implantes?
(Universidade Federal de Minas GeraisUFMG, 2011-12-20)
The aim of this study was to compare through a literature review the indications, no indications, advantages, disadvantages, predictability and applicability of using intermediaries and abutment UCLA (Universal Long castable ...
Analysis of Torque Maintenance and Fracture Resistance after Fatigue in Retention Screws Made of Different Metals for Screw-Retained Implant-Borne Prosthesis Joints
(2021-01-01)
Purpose. The aim was to evaluate the effect of different metallic alloys used in the manufacture of retention screws for universal cast to long abutment (UCLA) abutments for external hexagon (HE) and Morse taper (MT) ...

(Universidade Estadual Paulista (UNESP), 2014)
Reverse torque evaluation in indexed and nonindexed abutments of Morse Taper implants in a mechanical fatigue test
(2019-03-01)
Background: This experimental study assessed reverse torque of indexed and nonindexed (NI) abutments in Morse Taper (MT) implants in a mechanical fatigue test. Materials and Methods: In this experimental study It was used ...
The Impact of Conical and Nonconical Abutments on Bacterial Infiltration at the Implant-Abutment Interface
(Quintessence Publishing Co Inc, 2016-11-01)
This study evaluated the in vitro bacterial microleakage at the implant-abutment interface of three prosthetic connections: external (EH) and internal hexagon (IH) and taper connection (TC: solid [ST], taper with internal ...
Capacity to maintain placement torque at removal, single load-to-failure, and stress concentration of straight and angled abutments
(2019-01-01)
Because the main complication of implant-supported prostheses is torque loosening and/or fixation screw fracture, the goal of this study was to evaluate the torque before and after fatigue (screw placement and removal, ...
Platform-Switching for Cemented Versus Screwed Fixed Dental Prostheses: Reliability and Failure Modes: An In Vitro Study
(Wiley-Blackwell, 2016-08-01)
Purpose: The aim of this study was to evaluate the probability of survival of cemented and screwed three-unit implant-supported fixed dental prostheses (ISFDP) using different implant-abutment horizontal matching configurations ...
