Use of Odontogenic Graft Obtained From Human Tooth and Low Level Laser Therapy

This prospective clinical trial will include systemically healthy adult patients who require extraction of at least two posterior teeth with a hopeless prognosis due to periodontal disease, root caries, or root fractures, and who are candidates for implant-supported posterior rehabilitation. Following atraumatic tooth extraction, only sites with intact alveolar socket walls will be included.

Extracted teeth will be processed to obtain an autogenous odontogenic graft material. Eligible extraction sockets will be allocated to one of the study groups: (1) odontogenic graft alone or (2) odontogenic graft combined with adjunctive low-level laser therapy. In the laser group, LLLT will be applied according to a standardized protocol during the early healing period to promote cellular activity and bone regeneration.

Clinical and radiographic evaluations will be performed at baseline and at predefined follow-up intervals to assess soft tissue healing, bone dimensional changes, and quality of regenerated bone prior to implant placement. The primary outcome measure will be the amount and quality of newly formed bone, while secondary outcomes will include socket healing, postoperative morbidity, and implant feasibility.

The results of this study aim to provide clinical evidence on the potential benefits of combining autogenous tooth-derived grafts with low-level laser therapy for alveolar ridge preservation and to support optimized treatment protocols for implant-supported posterior rehabilitation.
