STATEMENT OF PROBLEM A fundamental problem in fully understanding the dynamic nature of screw loosening is lack of recognition of the entire process of screw tightening and retightening. PURPOSE The purpose of this study was to explain the dynamic nature of abutment screw retightening by using finite element methods to investigate the effect of the coefficient of friction and retightening on the settling effect. MATERIAL AND METHODS Precise computer models were designed of a Straumann… CONTINUE READING
