Several recent systematic reviews have highlighted how the macrodesign of dental implants can influence stress distribution and biomechanical and biological behavior in implants immediately inserted in post-extraction sites. Finite element analyzes have confirmed the benefit of the inclination of the implant threads in reducing implant displacement in post-extraction sites, increasing primary stability, and decreasing stress in contact with the trabecular bone. Other comparative studies have shown that the design of the threads of the implant does not affect the distribution of stress in the surrounding bone. In view of the need to evaluate the influence of implant macrodesign in the case of implants inserted in post-extraction alveoli, this study will examine the clinical results of two different types of implants with different macrodesigns, with the aim of providing scientific evidence in this regard. The present study will investigate through a randomized controlled trial the effect of thread macrodesign of X-space implants on primary stability and osseointegration when inserted in post-extraction sites, as compared to cylindric 2P implants.
