研究目的:

本研究为前瞻性非随机临床研究,拟选择骨性安氏II类、III类需正畸-正颌联合治疗患者下前牙为研究对象,研究辅助增加舌侧骨增量牙周手术的可行性、有效性和长期安全性。计划完成各10例严重骨性安氏II类、III类错牙合畸形患者正畸-正颌联合治疗中配合牙周舌侧骨增量,以降低这两类错牙合畸形患者治疗中舌侧牙周软硬组织的风险、从而最大可能预防规避骨性II类、Ⅲ类错牙合畸形患者正畸-正颌序列治疗后出现牙周支持组织丧失引起的美学甚至功能风险。  

Objectives of Study:

This study would be performed as a prospective nonrandomized controlled trial which aim to study the feasibility, effectiveness and long-term safety of lingual augmented corticotomy periodontal surgery of lower anterior teeth in patients with severe skeletal class II and III patients requiring orthodontic-orthognathic treatment.It is planned to complete the 10 patients with severe skeletal class II and III malocclusion respectively in order to reduce the risk of lingual periodontal soft and hard tissue in the presurgical orthodontic procedure. Thus, the aesthetic and functional risks caused by loss of periodontal supportive tissue in patients with skeletal class II and III malocclusion after orthodontic and orthognathic sequential treatment should be prevented.

Case Record Form: According to the original paper observation records of patients, the data were timely, complete, correct and clear input into the case record form. The input mode is two-person and two-machine. Electronic Data Capture: After completing data entry and verification as required, the original data shall be filed and stored in serial order, and filled with retrieval catalogue for future reference. Electronic data files, including databases, code books and description files, are stored in different categories, and multiple backups are stored on different encrypted hard disks to prevent damage.
