Utilização de tórus mandibular para reconstrução parcial de rebordo alveolar atrófico em mandíbula - relato de caso clínico.

Abstract

Introduction: Aesthetic-functional rehabilitation through dental implants has grown over the years and there is a growing interest in methods that enable bone gain in atrophic alveolar areas. Unfavorable crown-to-implant ratio, inadequate support for implant locking and the possibility of long-term implant loss are results of the installation of osseointegrated implants in atrophic areas. Bone grafting can provide a volume gain in thickness, and among the available materials, autogenous bone graft is considered the “gold standard” because it has osteoconduction, osteoinduction and osteogenesis properties compatible with the receiving region. The mandibular torus is, indeed, a safe and efficient alternative, making it possible to install implants in a favorable three-dimensional position. Objective: To report a case of autogenous bone grafting whose donor region was a mandibular torus, for reconstructing the atrophic area in the mandible, aiming to increase the bone thickness available for the installation of a dental implant. Case report: A normossystemic 50-year-old male patient searched for dental services complaining about his smile. On the clinical examination, the patient presented bilateral mandibular torus and atrophic area in the left lower premolar region. A reconstruction procedure through the autogenous graft with right mandibular torus donor area, dental implant installation and implant-supported prosthetic rehabilitation were performed. Conclusion: It was proved that the mandibular torus is an efficient alternative of autogenous bone graft, which provides a sufficient volume gain for the implantation of the dental implant. The technique used in this case was efficient and safe, and could be reproduced by a well-trained professional.
