ObjectivesTo systematically review the effectiveness of one-phase treatment and two-phase treatment on the incidence of incisors trauma in patients with deep overjet, and to provide scientific basis for the selection of clinical treatment plans.MethodsPubMed, The Cochrane Library, Web of Science, CBM, CNKI, VIP and WanFang Data databases were searched to collect randomized controlled trials (RCTs) on the clinical effectiveness of one-phase treatment and two-phase treatment on the incidence of incisors trauma from inception to December 20^th, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed by using RevMan 5.3 software.ResultsA total of 4 studies were included involving 613 patients. The results of meta-analyses showed that, there was no significant difference in the final overjet after one-phase treatment and two-phase treatment (functional appliance and headgear) (MD=–0.23, 95%CI –0.57 to 0.11, P=0.19). However, the new incidence of incisor trauma was significantly less for two-phase treatment group (functional appliance and headgear) (RR=0.69, 95%CI 0.48 to 0.99, P=0.05).ConclusionsPatients underwent two-phase treatment have lower incidence of dental trauma than one-phase treatment. Due to limited quality and quantity of the included studies, more high quality studies are required to verify the above conclusion
