研究类型:

干预性研究

Study type:

Interventional study

研究所处阶段:

I期临床试验 

Study phase:

1

研究设计:

随机平行对照 

Study design:

Parallel 

研究目的:

1.证实在下颌阻生第三磨牙拔除手术后,患者拔牙创伤的愈合与去骨、分牙策略选择密切相关。 2.揭示运用刚体力学策略可以缩短下颌阻生第三磨牙拔除手术时间,减少术中、术后并发症的发生率。 3.规范下颌阻生第三磨牙拔除手术中使用刚体力学的方法,形成系统的评价体系,申报牙及牙槽外科新技术,减轻广大患者的拔牙痛苦。  

Objectives of Study:

1. It is confirmed that the healing of tooth extraction trauma after mandibular impacted third molar extraction is closely related to the selection of bone removal and tooth separation strategies; 2. It is concluded that the rigid body mechanics strategy can shorten the operation time of mandibular impacted third molar extraction and reduce the incidence of intraoperative and postoperative complications; 3. Standardize the use of rigid body mechanics in mandibular impacted third molar extraction, form a systematic evaluation system, declare new dental and alveolar surgery techniques, and alleviate the pain of tooth extraction for the majority of patients.

All removed IMTMs were completely impacted by mucous membranes, and ASM was a thick gingival biotype; 3. No caries, no loosening, no crown prosthesis, no loss of mandibular first molar; 4. According to the Winter classification and Pell and Gregory classification, select the BⅡ mesial or horizontal IMTMs, and the Angle between the maxillary plane and the mandibular plane of the mesial or horizontal IMTMs is 11°~100°; 5. The distance X1-X2(i.e. front gap of wisdom teeth) from the mesial most convex point of IMTM crown to the most concave point of ASM distal neck is 1mm; 6. IMTMs patients voluntarily participated in clinical examination and subgingival plaque sampling, with good compliance and regular follow-up.

排除标准:

1.患有系统性疾病的患者; 2.ASM 存在病变; 3.依从性差,或未规律治疗者; 4患者自行要求终止试验者或失联无法随访者。

Exclusion criteria:
