RESUMO
ABSTRACT: Objective: This study was reduction of a bilateral mandibular fracture through the installation of dental implants with immediate loading, re-establishing the stomatognathic function of the patient. Case Report: A 58-year-old male patient seek the emergency room from hospital after suffering a motorcycle accident. After physical and imaging examinations was diagnosed with bilateral mandibular fracture. The treatment of choice, once the patient was edentulous, was the reduction and stabilization of the fracture with the installation of 5 dental implants with immediate loading. After 1 year of postoperative follow-up, the facial contour along with the occlusion were reestablished. Radiographically, it was found the proper placement of plates and screws with correct baseline realignment and maintenance of implant-supported prosthesis. Conclusion: In this case report with follow-up of 18 months, the functional prosthetic rehabilitation and immediate aesthetic with immediate loading system, after reduction and fixation of mandibular fractures proved to be a good treatment option.

Piezosurgery is a new and modern technique of bone surgery in implantology. Selective cutting is possible for different ultrasonic frequencies acting only in hard tissues (mineralized), saving vital anatomical structures. With the piezoelectric osteotomy technique, receptor site preparation for implants, autogenous bone graft acquistition (particles and blocks), osteotomy for alveolar bone crest expansion, maxillary sinus lifting, and dental implant removal can be performed accurately and safely, providing excellent clinical and biological results, especially for osteocyte viability. The aim of this review was, through literature review, to present clinical applications of piezosurgery in implant dentistry and outline their advantages and disadvantages over conventional surgical systems. Moreover, this study addressed the biological aspects related to piezosurgery that differentiate it from those of bone tissue approaches. Overall, piezosurgery enables critical operations in simple and fully executable procedures; and effectively, areas that are difficult to access have less risk of soft tissue and neurovascular tissue damage via piezosurgery.
