Introduction: The loss of dental elements leads to alveolar changes through a progressive and chronic process of bone resorption, affecting the installation of osseointegrated implants and consequently their functional and aesthetic success, often requiring bone grafting in these atrophic areas. The use of mandibular torus as an autogenous graft has an excellent prognosis due to its properties that are compatible with the recipient area, in addition to having a shorter clinical time and lower cost. Objective: To analyze the literature on the use of bone graft derived from mandibular torus as a donor source for reconstruction of atrophic areas with a view to installing osseointegrated implants. Methodology: An systematic review was carried out in order to analyze the literature on the use of bone graft derived from mandibular torus as a donor source for reconstruction of atrophic area aiming at the installation of osseointegrated implants. Scientific articles without language restrictions were searched in three electronic databases: PubMed, Google Scholar and VHL, using the descriptors ''Dental Implant'', ''Bone Graft'', ''Exostoses'', ''Alveolar Ridge Augmentation '', searched using the Boolean operator “AND''. Results: A total of 13 articles were included in the final analysis. Twenty-four patients underwent removal of the mandibular torus and its use as an autogenous graft to increase the alveolar ridge. No patient had surgical complications or immunological rejection. Twenty-two patients were followed to confirm new bone formation, through imaging exams and histological analysis, with bone formation with histological characteristics and density similar to native bone. Finally, a total of nine implants were installed in the bone graft region, without presenting failures in osseointegration or pathological bone resorption. Conclusion: The use of the mandibular torus as an autograft is viable for increasing the alveolar ridge, being a safe and effective alternative. Bone neoformation and density after grafting presented characteristics similar to native bone, contributing to future rehabilitation with osseointegrated implants.
