摘要/Abstract

摘要： 目的：本文报道1例无托槽隐形矫治器联合种植支抗和舌刺矫治成年骨性Ⅱ类高角伴前牙开颌的病例。诊治经过：成年女性,骨性Ⅱ类高角型,磨牙中性关系,前牙开颌,采用无托槽隐形矫治器进行矫治,上下磨牙区植入支抗钉进行磨牙压低,上下前牙粘接舌刺纠正吐舌习惯。结果：经过26个月的正畸治疗,患者开颌改善,尖牙磨牙中性,上下中线一致,牙根平行度好,上齿槽座点-鼻根点-下齿槽座点夹角（A point-nasion-B point angle,ANB）减小,下颌平面角减小,侧貌改善,随访半年保持效果良好。结论：无托槽隐形矫治器联合种植支抗可在骨性Ⅱ类高角伴前牙开颌的正畸治疗中进行有效的垂直向控制,联合舌刺可同时改善吐舌习惯。

Abstract: Objective: In this case, an adult with skeletal ClassⅡ malocclusion and open bite was treated with clear aligners in combination with miniscrews and tongue spurs. Diagnosis and treatment: An adult female with skeletal ClassⅡrelationship, molar ClassⅠ relationship, hyperdivergent profile and anterior open bite was treated with clear aligners. The miniscrews were implanted in the molar regions for molar intrusion. The tongue spurs were placed in the anterior teeth to correct tongue thrusting habit. Results: After 26 months of orthodontic treatment, the open bite was closed, and bilateral ClassⅠmolar/canine relationship, dental midline consistency were achieved with optimal root parallelism, reduced ANB and mandibular plane angle. The lateral facial esthetics was improved as well. These treatment results were proved to be stable after six months of retention. Conclusions: Clear aligners combined with miniscrews for molar intrusion can provide effective vertical control during the treatment of skeletal Class Ⅱ malocclusion with a hyperdivergent profile and open bite. Tongue spurs are effective in correcting tongue spitting habits at the same time.
