Abstract
ObjectiveTo compare the therapeutic outcomes and side effects of lingual and labial fixed appliances.
MethodsPubMed, Cochrane Library, CBM, CNKI and Wanfang databases were used for retrieval. Meta-analysis was conducted using Stata/MP 16.
ResultsThe systematic review included 23 studies, and the meta-analysis included 10 of these studies. There was no significant difference in the overall treatment outcomes between lingual and labial appliances (PAR: P=0.050; ABO-OGS: P=0.624). However, the lingual appliance showed more issues in terms of the gingival index at the 12th week of treatment (P=0.042) and speech articulation. There was no significant difference in root resorption.
ConclusionsThere is no significant difference in treatment outcomes and root resorption between lingual and labial appliance. However, lingual appliances had a greater impact on speech and the gingival index.
