Apical stability of implants with progressive thread design in vitro, based on clinicians with different levels of experience.

Background: The implant design and the surgical technique are important parameters that can be modified to improve the implant primary stability. The aim of this study was to evaluate the role of the apical part of an implant on the implant stability of implants placed in Type II dense bone by novice and experienced clinicians.

Methods: Implants with a progressive thread design (3.
