摘要
Abstract
Objective To explore the method of orthodontic treatment of inverse impacted maxillary central incisor to improve clinical treatment effect and retain more inverse impacted incisor. Methods 8 patients with 9 inverse impacted maxillary central incisors were treated with methods of opening space, surgical fenestration and traction, fixed artificial fulcrum to adjust direction aligned, reverse root control and so on. Results Inverse impacted maxillary central incisors have normal position, stability teeth root and proper function after 15 to 30 months of orthodontic treatment. Another incisor without clear displacement was extracted after 15 months of orthodontic traction, because its root was short and bend 180°. Conclusion Inverse impacted maxillary central incisor with normal root or slightly short root, or bent root less than 100° can be retained and keep normal function completely through a series of orthodontic treatment. Fixed adjustable artificial fulcrum can assist in treating inverse impacted maxillary central incisor. It can effectively shorten the course of treatment and improve efficacy.关键词
