Abstract

Abstract: Objective: To investigate and analyze the clinical effect of full crown and band loop space maintainer on premature loss of single deciduous molar. Methods: From August 2020 to June 2021, 189 children with premature loss of single deciduous molars restored by band loop space maintainer and full crown space maintainer were analyzed retrospectively. The incidence of new dental caries, the incidence of gingival redness and swelling, and the survival rate of the gap retainer (falling off, loosening, and desoldering) were compared between two groups. Results: The incidence of caries and the survival rate of caries in the full crown group were better than those of band loop space maintainer. When the second deciduous molar was used as the abutment, the abutment status and retention rate of the control group were better than those of the experimental group. When the first permanent molar was used as the abutment, the abutment status of the control group was better than that of the experimental group (P<0.05). There was no significant difference in the incidence of gum swelling between two groups. When the first permanent molar was used as the abutment, there was no significant difference in the survival rate of the retainer between two groups (P>0.05). Conclusion: The full crown space maintainer has more advantages for premature loss of single deciduous molar.
