功能矫治对安氏Ⅱ类错牙畸形患者髁突位置影响的Meta分析
Meta-analysis of the condylar position changes produced by functional appliances in class Ⅱ malocclusion
摘要
Abstract
Objective This study aimed to analyze the condylar position changes produced by functional appliances in class Ⅱ malocclusion by systematic review.Methods Electronic search was conducted using Chinese Biomedical Literature Database, China National Knowledge Infrastructure, VIP Database for Chinese Technical Periodicals, Medline, Embase, Pubmed, and Cochrane Central Register of Controlled Trials. Studies on condylar position changes produced by functional appliances in classⅡ malocclusion were included. Risk of bias assessment and data extraction of included studies were con-ducted by two reviewers independently. The meta-analysis was carried out using Revman 5.1.Results Six studies were included (five high quality and one low quality). The condylar position showed no changes after Herbst treatment. The con-dylar posterior space after Twin-block treatment averagely increased by 0.31 mm (P<0.00001), whereas the condylar anterior space averagely reduced by 0.32 mm (P<0.00001).Conclusion Twin-block appliance enables forward movement of the condylar position. This result contributes to the correction of class Ⅱ malocclusion.关键词
