摘要: 目的 使用数字化三维模型分析方法,探讨长期配戴口腔矫治器治疗阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrome, OSAHS)患者的变化。方法 将18例长期配戴口腔矫治器的患者治疗前与治疗后的硬石膏模型导入Geomagic Studio 2014三维模型分析软件中,进行变化的数字化三维模型分析。采用SPSS 22.0软件包中的配对t检验对治疗前、后的数据进行比较。结果 18例患者配戴口腔矫治器平均为(6.57±1.98) a,治疗前、后部分牙变量有统计学差异。总体牙变化趋势在单颗牙变化上表现为上颌前磨牙段压低,上颌后牙颊倾和下颌后牙近中移动;在上颌表现为上颌牙弓长度减小,上颌后牙段牙弓增宽以及上颌牙弓深度减小,下颌在治疗前、后颌内变化无统计学差异;颌间关系表现为上、下前牙覆盖显著减小,其余变量在治疗前、后无显著变化。结论 长期配戴口腔矫治器存在的个别变量的变化,应定期随访,谨慎选择适应证。总体上导致牙变化的副作用轻微,安全性较高。

Abstract: PURPOSE: The aim of the study was to investigate the dental changes of patients with obstructive sleep apnea hypopnea syndrome (OSAHS) with long-term treatment of oral appliances, via the method of three-dimensional model analysis. METHODS: Using Geomagic Studio 2014 software, we transferred the dental models, which were from 18 OSAHS patients before and after treatment of oral appliances, into three-dimensional models for digital analysis. Datasets obtained from pre- and after treatment were compared for accuracy via paired t test using SPSS 22.0 software package. RESULTS: Eighteen patients using oral appliances for 6.57±1.98 years, showed significant differences in some dentition values between pre-treatment and after-treatment. The total dentition changes indicated intrusion of upper premolars, buccalization of upper posterior teeth and mesialization of lower posterior teeth. Statistical analysis demonstrated decrease in upper dental arch length, increase in upper posterior arch width and decrease in upper arch depth and dramatic reduction of overjet in anterior teeth. In the same time, other values evaluated showed no significant change before and after treatment of oral appliances. CONCLUSIONS: Long-term wearing oral appliances results in changes in several variables of dental occlusion, which should not be ignored for dentists conducting this treatment plan. However, the side effect of dental occlusion changes is little on a whole, leading to high security in this aspect.
