Soft Tissue Width and Abutment Height Influence Peri-implant Bone Resorption

The purpose of this clinical and radiographic study will be to determine what influence on marginal bone loss has the thickness of soft tissues and the height of the prosthetic abutment and eventually determine which of the two factors is the most important.This research was designed as a multicentre cohort study. Two clinical centers will treat patients through the placement of a single dental implant. The implants will be prosthetically loaded about 4 months after placement and periapical radiographs will be acquired at each time-point.
