The Effect of Photobiomodulation on Distraction Osteogenesis

et al. 2019

Distraction osteogenesis (DO) is a surgical procedure to increase bone height in different body parts. DO includes a surgical incision, wherein the bone is cut and a device is installed for further separation of the two ends by gradual unscrewing of the device screw. New bone gradually forms and fills the gap, and the bone height increases as such. Photobiomodulation (PBM) or low-level laser therapy (LLLT) enhances the formation of soft and hard tissue such as bone and can, therefore, accelerate the process of DO and shorten the duration of different surgical phases of DO such as latency, activation, and consolidation. Different laser types with variable exposure settings and protocols have been used for this purpose. The gallium-aluminum-arsenide (GaAlAs) diode laser is the most commonly used laser type for LLLT. This study reviews 18 published articles on the effects of LLLT on DO and summarizes their findings to further elucidate this topic.

“…Taha et al concluded that LLL created a number of environmental conditions that could increase the osteoblast and osteoclast activity, enhance collagen synthesis, accelerate the healing of bone defects, stimulate the formation of bone callus and production of the bone matrix. Additionally, LLL had a significant biostimulatory effect on differentiation of mesenchymal cells into osteoblasts rather than chondroblasts ( Taha et al, 2018 ).…”

Distraction osteogenesis (DO) is a kind of bone regeneration technology. The principle is to incise the cortical bone and apply continuous and stable distraction force to the fractured end of the cortical bone, thereby promoting the proliferation of osteoblastic cells in the tension microenvironment and stimulating new bone formation. However, the long consolidation course of DO presumably lead to several complications such as infection, fracture, scar formation, delayed union and malunion. Therefore, it is of clinical significance to reduce the long treatment duration. The current treatment strategy to promote osteogenesis in DO includes gene, growth factor, stem-cell, physical and pharmacological therapies. Among these methods, pharmacological and physical therapies are considered as safe, economical, convenience and effective. Recently, several physical and pharmacological therapies have been demonstrated with a decent ability to enhance bone regeneration during DO. In this review, we have comprehensively summarized the latest evidence for physical (Photonic, Waves, Gas, Mechanical, Electrical and Electromagnetic stimulation) and pharmacological (Bisphosphonates, Hormone, Metal compounds, Biologics, Chinese medicine, etc) therapies in DO. These evidences will bring novel and significant information for the bone healing during DO in the future.

São Paulo: Universidade de São Paulo, Faculdade de Odontologia; 2018. Versão Original. The process of bone repair after tooth extraction is a physiological phenomenon which results in alterations of the bone dimensions and could interfere in prosthetic rehabilitation. To minimize bone loss, strategies for border preservation have been used and photobiomodulation therapy (TFBM) stands out as a low cost option and morbidity. Previous studies have shown the positive impact of TFBM on bone repair.The aim of this study was to evaluate the effect of TFBM on alveolar repair. Twenty patients with exodontia indication of the first or second molar bilaterally were chosen, right and left sides were distributed in one of the following experimental groups: (1) TFBM, treated with low frequency laser, and (2) Control group, who received the same treatment with the equipment off; besides, laser application was applied right after the post-operatory, after 1, 2, 3, 4, 7 and 15 days. After 45 days from the extraction, tissue samples from the alveoli were collected for micro-tomographic and histological analysis. Data were compared using the paired t-test and the accuracy level was 5%. A morphometric analysis showed statistically significant differences between the groups regarding the following parameters: bone surface (p = 0.029), bone surface / total volume (p = 0.028), trabeculae number (p = 0.025) and connectivity density (p = 0.029), higher in the TFBM group than in Control....
