Horizontally impacted maxillary central incisor:1 case report and literature review
Objective To investigate the etiology,diagnosis and treatment of a case of horizontally impacted maxillary central incisor and review relevant literature,so as to provide reference for the clinical treatment of such disease.Methods The data of cone beam computer tomography(CBCT),facial and intraoral photographs of the patient were retrospectively analyzed.Relevant literature in CNKI,VIP,Wanfang and PubMed databases were reviewed.Results The main manifestation included unerupted permanent central incisor,deciduous tooth retention,space loss,and inclination of adjacent teeth in mixed dentition.CBCT revealed crown labial growth,immature roots,curved roots with an approximate angle of 65° to the crown.After treatment,the impacted incisor moved into alignment,without external root resorption,sensitivity to percussion,mobility,or sensitivity to thermal stimuli.Conclusion It is an effective way to fix horizontally impacted maxillary central incisor with removable orthodontic appliances and sectional fixed orthodontic appliances,which can improve the preservation rate of affected teeth.
