Loosening torque of Universal Abutment screws after cyclic loading: influence of tightening technique and screw coating
PURPOSE The purpose of this study was to evaluate the influence of tightening technique and the screw coating on the loosening torque of screws used for Universal Abutment fixation after cyclic loading. MATERIALS AND METHODS Forty implants (Titamax Ti Cortical, HE, Neodent) (n=10) were submerged in acrylic resin and four tightening techniques for Universal Abutment fixation were evaluated: A ...
متن کاملEvaluation of screw loosening on new abutment screws and after successive tightening.
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 screws (G1) were used in a first moment. Subsequently, the same abutment screws were used a second time (G2) and more than two times (G3). The values of the torques applied a...
متن کاملComparison of the Effect of Two Different Abutment Diameters on Detorque Value Using Cyclic Loading and Thermocycling
Background and Aim: Screw loosening is a common problem with both screw-retained and cemented implant restorations. It is assumed that the abutment diameter affects detorque value and screw loosening. We aimed to determine the effect of two different abutment diameters on detorque value using cyclic loading and thermocycling. Materials and Methods: This in-vitro experimental study was conducte...
متن کاملInfluence of the implant abutment types and the dynamic loading on initial screw loosening
PURPOSE This study examined the effects of the abutment types and dynamic loading on the stability of implant prostheses with three types of implant abutments prepared using different fabrication methods by measuring removal torque both before and after dynamic loading. MATERIALS AND METHODS Three groups of abutments were produced using different types of fabrication methods; stock abutment, ...
متن کاملبررسی میزان کاهش تورک در اباتمنت‌های کست شونده با آلیاژ کروم کبالت پس از اعمال بارگذاری دوره‌ای
Background and Aims: For the clinical success of implant-retained prostheses, fitness of matching components and stability of the applied torque to the implant-abutment assembly under dynamic occlusal loading is essential. The aim of this study was to evaluate the torque loss in Co-Cr castable abutments after cyclic loading. Materials and Methods: 10 castable abutments were cast in Co-Cr alloy...
