Abutment 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 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 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...
متن کاملEffect of Double Screw on Abutment Screw Loosening in Single-Implant Prostheses.
PURPOSE This study was conducted to assess the effect of using a double screw on the prevention of abutment screw loosening. MATERIALS AND METHODS Internal connected abutment with a single screw (IS), internal connected abutment with a double screw (ID), external connected abutment with a single screw (ES), and external connected abutment with a double screw (ED) groups were prepared (n = 10 ...
متن کاملAn abutment screw loosening study of a Diamond Like Carbon-coated CP titanium implant.
The aim of this study was to quantify the extent of abutment screw loosening and thus understand the role of frictional and wear factors in abutment screw loosening by using a cyclic loading device to compare Diamond Like Carbon (DLC)-coated and non-coated implants. The properties of DLC films, including hardness, wear resistance, chemical stability, and biocompatibility, are similar to those o...
