Computer-guided bone lid osteotomy with piezosurgery.

Aim: The aim of this paper is to present a case of mandibular cyst in proximity to the left inferior alveolar nerve and the adjacent teeth successfully treated with computer-guided bone lid technique. Case presentation: A patient was referred to our Department with an asymptomatic radiolucent lesion in the left mandible coinciding with the edentulous site of a second premolar. The lesion was confirmed using cone-beam computed tomographic imaging. Two tooth-supported computeraided design/computer-aided manufacturing guided surgical templates were designed and produced to guide the piezoelectric tips on the planned osteotomy planes. The cystic lesion was accessed through a buccal bone lid fashioned using a piezoelectric device. The lesion was removed and the bone lid was returned to its original position and stabilized with fixation microplates. Conclusions: Alveolar bone lesions can be treated successfully with bone lid techniques using piezosurgery. Computer-guided bone surgery offers the advantages of accurate and conservative surgical planning, enabling a safer and easier procedure.
