Supraeruption can be defined as a phenomenon whereby the crown of the tooth erupts beyond the occlusal plane. Occlusal plane disruption can result in improper distribution of occlusal force resulting in trauma from occlusion. Supraeruption of teeth with opposing missing teeth will lead to migration of the gingival margin and increase in the crown height. The aim of this study was to determine the association of supraeruption with relation to opposing missing teeth. A retrospective study was done in an institutional setting to study the association of supraeruption and opposing missing dentition. Among patients who have visited the dental facility, the records of the patients were obtained from a given time period of June 2019 to April 2020. The patients case sheets were analysed using parameters which are supraerupted teeth (upper posteriors & lower posteriors), opposing missing (upper posterior, lower posterior, & NIL) and gender. The data was sorted and was tabulated in excel. Analysis of data was done in SPSS software. The association of supraerupted teeth and its correlation to opposing missing teeth was evaluated. Total of 153 supraerupted teeth were noted. It was found most of the supraerupted upper posteriors had missing lower posteriors (81.05%) whereas some had no missing opposing teeth (12.42%). In all supra erupted lower posteriors, the upper posteriors were missing (6.54%). .Significant association between supraeruption and opposing missing teeth.
