Influence 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 کاملCorrelation between microleakage and screw loosening at implant-abutment connection
PURPOSE This study aimed to evaluate the correlation between microleakage and screw loosening at different types of implant-abutment connections and/or geometries measuring the torque values before and after the leakage tests. MATERIALS AND METHODS Three different abutment types (Intenal hex titanium, internal hex zirconium, morse tapered titaniuım) with different geometries were connected to...
متن کاملLoosening 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 کاملAbutment screw loosening in single-implant restorations: a systematic review.
PURPOSE The purpose of this study was to systematically review clinical studies on the incidence of abutment screw loosening in single-implant restorations with different implant-abutment connection geometries. MATERIALS AND METHODS The literature search was conducted using several electronic databases. Specific terms were used for the database search, which spanned the years 1990 to 2006. Th...
متن کاملEffect of Casting Procedure on Screw Loosening of Ucla Abutment in Two Implant-abutment Connection Systems
Since Bra�nemark et al published the results of a 10-year study on osseointegration in 1977, dental implants have increasingly been used to replace missing teeth. The use of osseointegrated implants had become a successful procedure for the treatment of complete, partial edentulism, and single-tooth replacements in both the anterior and posterior regions of the mouth. Although improvements in m...
