    Author(s): Shaiq Gajdhar*

    Background: The dental implant abutment connection plays a very crucial role in the quality of the stress distribution, and, over the years, different designs were proposed. Most common complication after the dental implant treatment is abutment screw loosening that adversely affects the outcomes of implant rehabilitation. Therefore, this study was aimed to correlate the abutment screw loosening at four different torques and to study the stress and deflection pattern of the abutment screw using three - dimensional finite element analysis. Methods: Three dimensional computer aided designed (CAD) models were generated, which were having a detailed geometry of the implant, abutment, abutment screw, surrounding hard and the soft tissues of the mandibular jaw. The abutment screw was than torqued at 10 Ncm. One point load of 170 N was then applied 30o oblique to the long axis of implant. Th.. Read More»
