Labial Bone Thickness Change in Immediate Implant Placement In Maxillary Esthetic Zone

Recruiting now · Not applicable

Conditions studied: Guided Immediate Implant Placement, Jumping Gap, Labial Bone Thickness Change, Broken Down Tooth Rehabilitation

In brief

The goal of this clinical trial is to assess the effect of distance between the implant and the bone on the resultant bone thickness adjacent to the implant in place of a broken down tooth that happens to be bounded by two natural teeth. The main questions it aims to answer are: Does the horizontal implant position (and hence the gap between the implant and the socket wall i.e. jumping gap) affect the resultant labial bone thickness? Will it affect the quality of soft tissue, esthetics and patient satisfaction? Participants will have an implant placed using a surgical guide with a jumping gap either less than 2 mm or equal or more than 2 mm and will be asked to visit the clinic once every 3 months for checkups, radiographs, and readings.
