Laser Therapy Treatment of Peri-implantitis.

Influence of Laser Therapy Upon Surgical Treatment of Peri-implantitis Lesions.

The primary objective of this study is to compare the clinical outcomes of using Er: YAG laser along with bone graft and barrier membrane to conventional mechanical debridement also with bone graft and barrier membrane in the treatment of peri-implantitis infections.
