国产无托槽隐形矫治技术的临床应用初探

目的 将我国自主研发的无托槽隐形矫治技术应用于口腔正畸临床,探讨该矫治器的临床应用情况、存在的问题以及应用前景.方法 选取41例较简单的错(牙合)畸形患者,主要包括牙列间隙、牙列拥挤以及牙周病止畸治疗,应用国产无托槽隐形矫治技术进行正畸治疗.通过层析扫描建立数字化三维牙颌模型,通过激光快速成形技术加工无托槽隐形矫治器,根据治疗方案,为每例患者设计10～40副矫治器.患者每2～3周更换一副矫治器,矫治后评估疗效.结果 所有病例均完成矫治并取得良好的矫治效果,矫治后牙列排齐、无间隙、前牙覆(牙合)覆盖正常,矫治疗程6～25个月,平均18个月.结论 目前,国产无托槽隐形矫治技术仅町矫治相对简单的错(牙合)畸形,并以其透明、美观、舒适、卫生等优点,而具有良好的临床应用前景.

Preliminary clinical application of Chinese-made invisible orthodontic technique

Objective To treat simple malocclusions preliminarily using Chinese-made invisible orthodontic aligners and discuss the indications, problems existed and future development. Methods Forty-one cases with different malocclusions were selected, including crowding, spaces and spaces due to periodontal problems. Invisible aligners were made and worn by patients and they were changed every 2-3 weeks. Results Acceptable treatment results were obtained in all cases, with nice alignments and good overbite and overjet. Treatment time ranged from 6-25 months.
