Removal torque of zirconia abutment screws under dry and wet conditions
(Fundação Odontológica de Ribeirão Preto, 2010)
The aim of this study was to verify whether screw abutment lubrication can generate higher preload values compared to non-lubricated screws, a titanium abutment was screwed onto an implant analog and scanned with the Procera ...
Evaluation of Torque Maintenance of Abutment and Cylinder Screws With Morse Taper Implants
(Lippincott Williams & Wilkins, 2013)
Effect of Vertical Misfit on Screw Joint Stability of Implant-Supported Crowns
(Springer, 2011-08-01)
The passive fit between prosthesis and implant is a relevant factor for screw joint stability and treatment success. The aim of this study was to evaluate the influence of vertical misfit in abutment-implant interface on ...

Evaluation of screw loosening on new abutment screws and after successive tightening
(Fundação Odontológica de Ribeirão Preto, 2011)
This study evaluated the loss of the torque applied after use of new screws and after successive tightening. Four infrastructures (IE), using UCLA castable abutment type, were cast in cobalt-chromium alloy and new abutment ...
The Role of Implant/Abutment System on Torque Maintenance of Retention Screws and Vertical Misfit of Implant-Supported Crowns Before and After Mechanical Cycling
(Quintessence Publishing Co Inc, 2013-03-01)
Purpose: This study aimed to evaluate the role of the implant/abutment system on torque maintenance of titanium retention screws and the vertical misfit of screw-retained implant-supported crowns before and after mechanical ...
An In Vitro Comparison of Joint Stability of Implant-Supported Fixed Prosthetic Suprastructures Retained with Different Prosthetic Screws and Levels of Fit Under Masticatory Simulation Conditions

Influência da altura do abutment angulado na distribuição das tensões em implantes de hexágono externo com próteses unitárias implantossuportadas
(Universidade Estadual Paulista (Unesp), 2010-09-23)
The aim of this study was to evaluate the influence of the height of angled abutments for single implant-supported prostheses with external hexagonal implant, by means of photoelasticity. It was confectioned two models in ...
