Abstract：AIM:To evaluate the clinical effects of glass fiber-reinforced composite resin maintainer (GFRCR)and the band-and-loop space maintainer (BLSM).METHODS:42 children with bilateral mandibular second molar loss were included.GFRCR was used in one guadrant and BLSM in other the other quadrant.Plaque in-dex (PLI),sulcus bleeding index (SBI)and probing depth (PD)of the abutment teeth,and the success rate of the space maintain were recorded 1 ,3 and 6 months after wearing the maintainers.RESULTS:The children in both groups had higher PLI and SBI indexes 1,3,and 6 month after wearing the maintainer than before(P<0.05),and in GFRCR group was lower than in BLSMgroup (P <0.05).In GFRCR group,no significant difference was found in PD before and 1 month after wearing the maintainer,however,at 3 and 6 month PD were significantly higher than be-fore (P<0.05),but lower than in BLSMgroup (P <0.05).The success rates of the 2 groups were not statistically defferent (P>0.05).CONCLUSION:GFRCR space maintainer is a new clinical selection of space retainer.
