Effectiveness of sealing gel on vertical misfit at the implant-abutment interface and preload maintenance of screw-retained implant-supported prostheses
(2020-01-01)
Purpose: This in vitro study evaluated the effectiveness of a sealing agent on v: ertical misfit of the implant-abutment interface in an external hexagon implant system before and after mechanical cyclic loading. Effects ...
Evaluation of Torque Maintenance of Abutment and Cylinder Screws With Morse Taper Implants
(Lippincott Williams & Wilkins, 2012-11-01)
The screw loosening of implant-supported prostheses is a common mechanical failure and is related to several factors as insertion torque and preload. The aim of this study was to evaluate the torque maintenance of retention ...

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 ...
Influence of Abutment Type and Esthetic Veneering on Preload Maintenance of Abutment Screw of Implant-Supported Crowns
(2013-06-05)
Purpose: The effect of veneering materials on screw joint stability remains inconclusive. Thus, this study evaluated the preload maintenance of abutment screws of single crowns fabricated with different abutments and ...

Mechanical behavior of different micro conical abutments in fixed prosthesis
(2018-01-01)
Purpose: To evaluate the biomechanical behavior between two different micro conical abutments: two-piece and one-piece abutments. Materials and Methods: Four groups were divided according to the prosthetic connection ...
Influence of repeated screw tightening on bacterial leakage along the implant-abutment interface
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Objectives Bacterial penetration along the implant-abutment interface as a consequence of abutment screw loosening has been reported in a number of recent studies. The aim of this in vitro study was to investigate the ...
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 ...
