Submerged Vs Non-Submerged Guided Bone Regeneration Simultaneous to Implant Placement.

Dental implants are worldwide recognized one of the best manners to replace lost or hopeless prognosis teeth. There are different variables that creates proper conditions for long-term prognosis of implant treatments. Implant position and surrounding bone around them, have been described in scientific literature to be key factors in the longevity of those treatments. It has to be defined the \"critical bone thickness\" around implants. It basically means that implants has to be completely surrounded by bone, that will serve as protection. If the implants are not surrounded by bone, procedures as guided bone regeneration may be performed. Those procedures can be executed before or simultaneously during the implant placement. In the standard procedure, the simultaneous guided bone regeneration during implant placement requires to leave the implant and the regeneration healing below the gingiva, needing a second surgery for accesing to those implants. In this randomized controlled trial the hypothesis is to discover if not submerging this regenerations may show the same results than submerged ones. For that, the objective is to study the different variables around these regeneration to evaluate the performance of non-submerged protocol.
