Abstract The purpose of this study was to evaluate the survival rate and the incidence of prosthetic complications of 377 implants with a double octagon connection. Furthermore the correlations among implant dimensions (diameter and length), bone quality and insertion torque were investigated.A four-year multi-center prospective clinical study was designed to evaluate the survival rate of 377 dental implants, inserted on 189 patients between January 2004 and April 2010 with an average follow-up of 46 months. The implant survival rate was 99,7%. The incidence of complication was 0,53%. Moreover insertion torque was statistically related in a significant way to the implant diameter.The connection system in exam seems to reduce the unscrewing risk of the prosthetic components. Within the limits of this study, it is observed that at the wider diameter corresponds a higher implant primary stability. The implant length instead, seems not to be critical to obtain higher primary stability.

Abstract

Abstract The purpose of this study was to evaluate the survival rate and the incidence of prosthetic complications of 377 implants with a double octagon connection. Furthermore the correlations among implant dimensions (diameter and length), bone quality and insertion torque were investigated.A four-year multi-center prospective clinical study was designed to evaluate the survival rate of 377 dental implants, inserted on 189 patients between January 2004 and April 2010 with an average follow-up of 46 months. The implant survival rate was 99,7%. The incidence of complication was 0,53%. Moreover insertion torque was statistically related in a significant way to the implant diameter.The connection system in exam seems to reduce the unscrewing risk of the prosthetic components. Within the limits of this study, it is observed that at the wider diameter corresponds a higher implant primary stability. The implant length instead, seems not to be critical to obtain higher primary stability.
