超声骨刀在下颌后牙区改良式骨劈开术中的应用
Application of the modified split crest technique of piezosurgery in mandible molar area
摘要
Abstract
Objective To evaluate the therapeutic outcome of horizontal bone augmentation by using the modified split crest technique of piezosurgery in mandible molar area. Methods The present study reviewed the record of 15 patients from 2016 January to 2017 March in the department of oral implantology center of Stomato-logical Hospital of Southern Medical University,who underwent the modified split crest technique of piezosurgery in mandible molar area. Preoperative CBCT was performed to determine the bone thickness of the toothless alveo-lar crest of the mandibular posterior region,and the bone thickness was less than 3 mm. The modified split crest technique of piezosurgery was performed for the horizontal bone augmentation at mandibular posterior region. Meanwhile,GBR and the postoperative CBCT were performed to determine the bone width increments,followed with 1-week anti-inflammatory therapy postoperation. Three months after the operations,the bone width incre-ment was examined by CBCT. SPSS13.0 software was used to analyze the collected data. Results The modified split crest technique of piezosurgery in mandible molar area was successfully established,resulting in the mini-mal operative wounds and the slight postoperative reaction,without obvious infection. The postoperative crest width increase achieved 6.05 ± 0.65 mm. At 3 months after operation,the crest width increase reduced to(5.81 ± 0.61)mm. There were significant differences of the alveolar ridge thickness between the preoperative and post-operative patients(P<0.05). There were significant differences between the preoperative crest width and the 3 months after treatment(P<0.05). Conclusion Horizontal bone augmentation of the modified split crest tech-nique of piezosurgery was efficient,which could be performed in very narrow alveolar ridge,and which was rela-tively safe and accurate,with less trauma. No damage was observed to the soft tissue,and the cutting direction can be well controlled.关键词
