Abstract

This study aimed to investigate the application of piezosurgery-associated flapless surgery for increasing bone space during teeth extraction and evaluate its success rate, postoperative outcomes, and incidence of major complications.From January 2014 to December 2016, patients who experienced teeth extraction via piezosurgery-associated flapless surgery were enrolled in this study. The positions, diagnosis, dental medical history, and radiographic examination of teeth were recorded before the treatment. During the surgery, the fracture or displacement of root, injuries of soft tissue, and fractures of the alveolar process were noted.A total of 140 patients fulfilled the eligibility criteria in the present study. All these teeth were classified into 4 groups based on diagnosis: residual roots that underwent root canal therapy (28 cases), teeth with root fracture (37 cases), teeth extraction because of orthodontics needed (31 cases), and the vertically impacted lower third molar (44 cases). The radiographic presentation revealed about 50% ankylosed teeth. No root fracture and root displacement emerged, and all roots were removed intact. Moreover, fracture of the alveolar process did not occur. Two cases with buccal mucosal injury were noted, which were because of heat injuries caused by the basement of the tip while cool water was used out.This study introduced a novel mini-invasive strategy for increasing space during teeth extraction. The advantage of this piezosurgery-associated flapless surgery included maximal preservation of the alveolar bone, minimal injury to soft tissues, and prevention of root fracture during the surgery. Furthermore, the cool water used during the surgery must be carefully checked before the procedure.
