Buccal Bone Resorption in Immediate Implants in Thin and Thick Buccal Plates of Bone in Esthetic Zone

Study Overview
=================
Brief Summary
-----------------
To achieve esthetic immediate implants a minimum of adequate buccal bone thickness must be present. It was postulated that 2 mm of buccal bone thickness was needed to prevent recession of the buccal plate. However, this was reduced to 1 mm with more ongoing research. In a recent study postulated that a buccal bone thickness less than 1 mm could be sufficient. Scarce literature was found that monitored the ridge alterations following implant placement. In regards to the controversies regarding the minimal initial buccal bone thickness required to perform immediate implant placement, our study aims to monitor the buccal bone thickness and soft tissue changes over a year from implant and prosthetic placement.
