Background & Objectives: Immediate loading of implants became a necessity in order to reduce the period of osseointegration. Photo biomodulation is a non-invasive treatment that bio-stimulates the new-formed bone on the cellular level in order to improve the quality of bone around implants. This study aimed to evaluate the efficacy of Low-Level Laser on clinical stability of the immediately loaded implants.
Materials & Methods: 24 Megagen Implants were used in 12 patients in split mouth technique. 808 nm GaAlAs Laser with 4 J power per point was used for two weeks with an application every other day. The two implants in each patient were loaded immediately (1 week after implantation) by full acrylic crowns. Bone Mineral Density was estimated through Hounsfield unit HU which were registered from CBCT images before surgery and 3 months after implantation. For statistical analysis, T-test for independent groups and T-test for paired group were used to determine the differences between the two groups.
Results: No signifiable differences in HU values were noticed between the two groups in the operating day and 3 months after. While there were signifiable increase in bone density in the study group 3 month after surgery
Conclusions: Within the limitations of this study, using LLLt can improve the bone quality around implants but with no signifiable differences.
