Classification Research report
The aim of the investigation was to evaluate the periodontal status of the buccally impacted maxillary canines after orthodontic traction following closed eruption technique and to investigate pretreatment orthodontic variables affecting the periodontal changes.
54 patients with a maxillary canine in a buccally impacted position were chosen as an impaction group and a contralateral canine in normal position served as a control group.
Probing depth and bone probing depth increased significantly in the impaction group. The attached gingiva width was significantly shorter and the buccal clinical crown length longer in the impaction group. The distance from CEJ to AC was significantly longer and the bone supports shorter in the impaction group.
Forced eruption of the maxillary impacted canine after orthodontic traction following closed eruption technique resulted in significant gingival recession on the buccal side and alveolar bone loss on the interproximal sides.
