Abstract

This study aimed to evaluate the efficacy of PRF either alone, or mixed with 1% metformin gel, in horizontal ridge augmentation with split-crest technique, for implant placement.
Patients & Methods
24 implants were inserted in narrow ridges of twelve patients who were randomly assigned into one of two groups. In group 1, patients were treated by split crest technique with implant placement and PRF only. In group 2, patients received SCT with implant placement and 1% metformin gel mixed with PRF. Implant stability was recorded for every single implant immediately after insertion during surgery, and at 6 months. Modified Gingival Index, modified Plaque Index, and probing depth were recorded and repeated at one, 3, and 6 months. Immediately after surgery, at the time of loading, and 6 months after loading ridge width, crestal bone loss as well as bone density were evaluated.
