摘要
目的:本研究的目的是评估上颌切牙外伤(MIT)的存在与年龄、性别、牙列类型、覆盖程度(OJ)、唇形、呼吸类型和牙弓形状的关系。对象与方法:共纳入256例患者，平均年龄15.80±2.2岁。记录患者的性别、牙列类型、上唇形状、牙弓形状和呼吸类型。根据OJ严重程度分为四组:3.5 mm结果:3.5 mm结论:年龄、性别、呼吸类型和牙弓形态与MIT风险无显著相关。OJ在3.5 mm ~ 6mm之间(唇不全)和短唇增加了II类1分错牙合患者上颌切牙外伤的风险。
Maxillary incisor trauma in patients with class II division 1 dental malocclusion: associated factors.
Purpose: The aim of this study was to assess the association between the presence of maxillary incisor trauma (MIT) with age, gender, dentition type, the degree of overjet (OJ), lip form, respiratory type and dental arch form in patients with Class II division 1 dental malocclusion.
Subjects and methods: 256 patients (mean age: 15.80 ± 2.2) were included in this study. The patients' gender, dentition type, superior lip form, dental arch form and respiratory type were recorded. Participants were divided into four groups according to the severity of OJ: 3.5 mm
Results: 3.5 mm
Conclusion: The age, gender, respiratory type and dental arch form were not significantly associated the risk of MIT. OJ between 3.5 mm and 6 mm (with incompetent lip) and short lips increased the risk of having maxillary incisor trauma in patients with Class II division 1 malocclusion.
