Background: Tooth loss reduces crestal bone with important resorption of alveolar dimensions, reducing the possibility of placing implants after wounds healing. Objective: The goal of this pilot experience was to consider, in alveolar ridge preservation, the regenerative and decontaminating potential of oxygen high-level laser therapy (OHLLT), a high-frequency and high-power diode laser combined with hydrogen peroxide 10 volumes 3%, and to evaluate wound closure during the 14-21 days after surgery. Methods: For this study we selected 15 patients (age range from 30 to 70 years old) who underwent alveolar ridge preservation (three patients were treated in the anterior maxilla, 12 in the mandibular jaw, with molars and premolars involved). A clinical and radiographic examination was performed at baseline. In this pilot experience, after the extractions, the sockets were treated with photodynamic therapy without dye (OHLLT/SiOxyL+ protocol) to decontaminate the area that was treated, combined with allografts, Osteobiol, granulometry 25, Platelet-Rich Fibrin and collagen membranes, Biogide/Geistlich. Photobiomodulation (PBM) sessions with ATP38 were made for the first 4 months every 2 weeks. Clinical evaluations were performed at 14, 21, 90, and 240 days. Radiographic evaluations with cone beam computed tomography (CBCT) were performed at 240 days, before the second surgery. Two hundred seventy days after the first surgery, a new surgical treatment was made with the same concepts adopted in the first surgery, to place implants. Results: All alveolar ridge preservation surgeries were successful, with minimal bone resorption after 9 months. Closure of gingival tissue healed by secondary intention was achieved after 14 days for all patients, except one, who showed wound closure after 21 days. Conclusions: This pilot experience showed that this technique allowed to obtain new bone and wound healing by secondary intention in treated sites and to place implants in all patients, without other bone augmentation techniques, thanks to extracellular matrix induced by photodynamic laser therapy on grafts materials and to PBM made each 2 weeks for the first 4 months postsurgery. The study was conducted according to the guidelines of the Ethics Committee of the School of Medicine and Surgery at the Milano Bicocca University (protocol n. 11/17), and derived from the approval of Italian National Institute of Health (ISS), protocol 30 July 2007-0040488.

Abstract

Background: Tooth loss reduces crestal bone with important resorption of alveolar dimensions, reducing the possibility of placing implants after wounds healing. Objective: The goal of this pilot experience was to consider, in alveolar ridge preservation, the regenerative and decontaminating potential of oxygen high-level laser therapy (OHLLT), a high-frequency and high-power diode laser combined with hydrogen peroxide 10 volumes 3%, and to evaluate wound closure during the 14-21 days after surgery. Methods: For this study we selected 15 patients (age range from 30 to 70 years old) who underwent alveolar ridge preservation (three patients were treated in the anterior maxilla, 12 in the mandibular jaw, with molars and premolars involved). A clinical and radiographic examination was performed at baseline. In this pilot experience, after the extractions, the sockets were treated with photodynamic therapy without dye (OHLLT/SiOxyL+ protocol) to decontaminate the area that was treated, combined with allografts, Osteobiol, granulometry 25, Platelet-Rich Fibrin and collagen membranes, Biogide/Geistlich. Photobiomodulation (PBM) sessions with ATP38 were made for the first 4 months every 2 weeks. Clinical evaluations were performed at 14, 21, 90, and 240 days. Radiographic evaluations with cone beam computed tomography (CBCT) were performed at 240 days, before the second surgery. Two hundred seventy days after the first surgery, a new surgical treatment was made with the same concepts adopted in the first surgery, to place implants. Results: All alveolar ridge preservation surgeries were successful, with minimal bone resorption after 9 months. Closure of gingival tissue healed by secondary intention was achieved after 14 days for all patients, except one, who showed wound closure after 21 days.
