INTRODUCTION: The implant supported overdentures are considered a very successful treatment option for edentulous patients. Low level laser therapy (LLLT) has gained greater awareness in the last decade for implant surgery, reduces postoperative pain after surgery, promotes the osseointegration of implants, particularly, improving stability and enhances new bone formation without causing any tissue destruction. OBJECTIVES: : The aim of this study was the effect of low-level laser therapy on the biostimulation of bone repair by enhancing or accelerating osseointegration through stimulating the expression of osteoblastic phenotype in cells cultured on Titanium specimens. MATERIALS AND METHODS: 10 patients with age ranged between 45-60 years old were involved in the study. Each patient received 2 implants in the mandibular edentulous ridge at the canine area. The right side acted as study group has received one implant with a Semiconductor diode LASER (type IV) application, while the left acted as control one of same patients having normal loading in left mandibular canine area without LLLT application. All implants osseointegration was assessed by Magnetic Resonance Frequency Analysis to evaluate the implant stability. RESULTS Resonance Frequency Analysis evaluation revealed great difference in the stability after three months when irradiated with LLLT, implant stability quotient changes were found to be statistically significant between the two studied groups. (P2= <0.001). CONCLUSIONS: Effect of LLLT on bone remodeling is evident and improves implant stability.
