Abstract:
Objective:To compare the clinical effects of rapid maxillary expansion between tooth-borne and hybrid-borne expanders.Methods:PubMed,Cochrane Library,EMbase,CBM,CNKI,VIP and WanFang Data were searched from the date of their establishment to October 31,2015,to find clinical trials about comparison of rapid maxillary expansion by tooth tissue-borne versus hybrid-borne expanders.The quality of the included studies was evaluated by 2 independent reviewers,and Meta-analysis was performed by using RevMan 5.3 software.Results:8 articles with 206 cases were included.The results of Meta-analysis showed that:there were significant differences between the 2 groups in the changes of the right first molar dental inclination [MD =-1.62,95 ％ CI (-3.18,-0.07)],inter first premolar width [SMD =-0.86,95％ CI(-1.47,0.25)] and molar alveolar inclination [SMD =-0.86,95％ CI(-1.10,-0.20)].There was no significant difference between the 2 groups in the changes of inter first molar ~dth [SMD =-0.08,95％ CI (-0.6l,0.45)],the left first molar dental inclination [MD =-1.12,95％ CI(-2.57,0.33)],maxillary width [SMD =-0.30,95％ CI(-1.08,0.47)].Conclusion:The effect between tooth-borne and hybrid-borne expanders in the expansion of maxillary dental arch is similar.However,tooth-borne expanders may cause greater inclination of first molar and alveolar process.
