Evaluation of Diode Laser Treatment on Implant Stability, Healing Edema and Implant Survival in a Sample of Iraqi Patients Seeking Dental Implants: Single Center Study

Objective: To investigate the impact of diode laser therapy on pre-implant site preparation and post-implant healing, primary and secondary stability of the dental implant osteointegration, to measure crestal bone level, and the survival rate of the dental implants. Methods: This prospective clinical study was organized from November 2022 to August 2024 at the Dentistry College Teaching Hospital, Department of Oral and Maxillofacial Surgery/Dental Implant Unit/University of Kut. Patients were randomly allocated into two groups: study group receiving diode laser and control group receiving no laser treatment. Outcome variables included mainly healing edema score, implant stability, and survival of implant. Results: Regarding primary stability, there was no significant difference in its mean level between study group and control group, 67.12 ±5.44 ISQ versus 68.54 ±5.77 ISQ, respectively (p = 0.208). Regarding secondary stability following 7 days, 4 weeks, 8 weeks, and 12 weeks, there was no significant difference in its mean level between study group and control group (p> 0.05). Higher scores of healing edema were found in the control group when compared to study groups at 3 days, 7 days and 14 days intervals (p< 0.001). Conclusion: Laser therapy resulted in improved healing edema score, but it had no significant impact on dental stability or implant survival.
