Abstract

Long-term success of dental implants depends on implant abutment connection. This prospective study aims to assess the implant stability of self locking conical connection and traditional platform implant abutment connection with mandibular telescopic supported overdenture.

This study is a randomized controlled study included twelve completely edentulous patients selected from the Outpatient Clinic of the Prosthodontics Department, Faculty of Dentistry, Minia University.Two root form implants were inserted in canine area bilaterally in each patientone is self -locking implant abutment connection while the other is traditional platform. Telescopic overdenture was constructed over the two implants. The stability was evaluated at 3, 6, 9 and 12 months. The collected data were analyzed by SPSS program version 20 with considering statistical significance when P value<0.05.

There was no significant difference in implant stability regarding mean implant index when evaluated at delivery and various intervals with self locking conical implant abutment connection. While with traditional implant abutment connection there was significant difference in implant stability when evaluated at delivery and 6 months interval.

The self locking conical implant abutment has more stability rather than traditional platform implant. This is may be explained by that the self locking conical implant abutment interface optimize the ability of an implant-to-abutment joint to resist bending forces and micromotion increasing implant secondary stability.
