Crestal Bone Changes Following Equi-crestal Versus Subcrestal Implant Placement
Sponsor: Misr International University
Summary
Statement of problem: The stability of peri-implant bone is a crucial factor for the long-term success of dental implants, where crestal bone plays a significant role in both the primary as well as the long- term implant stability. A bone loss of 1.5 mm during the first year of loading has been acceptable according to the early standards. However, more bone stability can be expected with the development in implant designs and surfaces over the past decades. Aim of the study: the aim of this study is to radiographically assess the crestal bone changes following delayed implant placement in mandibular previously augmented posterior sites, comparing cases with equicrestal implant placement with subcrestal implant placement
Official title: Radiographic Evaluation of Crestal Bone Changes Following Equi-crestal Versus Subcrestal Implant Placement in Mandibular Posterior Augmented Ridge. A Randomized Controlled Clinical Trial.
