Abstract

Purpose: The aims of this study were to: 1. Compare the fracture strengths of four different implant systems, and 2. Evaluate the failure mode of the implants. Materials and methods: A total of eighty-eight (n=88) screw implants were tested. Forty-four for compressive strength and forty-four were tested for fatigue. Each implant body were inserted into a 30 degree holding device and adapted to be used in the BOSE 3330 Electro Force Testing System. A metal sphere was placed in the contact point of the implants (ISO 14801). The compression load was applied to each specimen at a rate of 0.02 inch per minute until failure. For the fatigue testing the step-stress accelerated testing at 17 Hz with 3 increment stages of 300.000 cycles each was performed. The fracture surface was evaluated by X400 Olympus microscopy. Discussion: The failure of the Integrity Tapered Implants -1 and -2 piece abutment connection was an identical combined bending of the implant-abutment Connection. Conclusion: The Integrity implant-2 pieces implant-abutment connection presented a higher resistance value to lateral compressive loads compared to the others implant-abutment connections.
