摘　　要：目的:评价不同矫治器矫治成人牙周病前牙扇形散开患者治疗前后牙周及牙槽骨状态的改变。方法:选择成人牙周病正畸治疗患者40例,随机分成两组。A组:使用Damon Q高转矩矫正器;B组:使用MBT传统直丝弓矫治器。矫治前(T1)和矫治6个月后(T2),对上前牙区牙周指数及使用CBCT对上前牙区牙槽骨密度进行检测,采用SPSS16.0软件包对测量数据进行配对t检验和独立样本t检验。结果:两组牙周病患者正畸治疗前后牙周指数比较无显著性差异,牙槽骨密度均稍有降低,差异有统计学意义(P<0.05)。但两组间比较,各项指标差别无统计学意义。结论:不同矫治器对于成年牙周病患者牙周状况包括牙槽骨状态改变的影响不明显。Objective To evaluate the effect on the periodontal status including the dental alveoar status in the treatment of adult periodontitis patients with scattering gap of the anterio teeth by different brackets. Methods Fourty adult periodontitis patients with scattering gap of the anterio teeth, who needed orthodontic treatment, were selected. The patients were divided into two groups of 20,A group treated with Damon Q self-ligating brackets and B group treated with conventional MBT brackets, respectively. The periodontal indexes of the upper incisors and canines were recorded before orthodontic treatment （T1） and after six months of orthodontic treatment （T2）. The alveolar bone densinty index （ABI） of upper incisors based on CBCT study was also recorded in the two stages. The data were analyzed by SPSSll6.0 software package for paired t test and independent-samples t test. Results All periodontal indexes of each group were not significantly different between T1 stage and T2 stage（P〉0.05）, but ABI was significantly different between T1 stage and T2 stage（P〈0.05）. The improvement from T2 to T1 was not significant between Damon Q group and MBT group （P〉0.05）. Conclusion The diffent brackets did make no difference on the effect of the periodontal status including the dental alveolar bone condition in the aldut peridontitis patients.
