Orthodontic treatment carries potential risks and complications, especially if the path of tooth movement extends beyond the alveolar bone or if the patient has a thin bone plate. This amplifies the patient's risk of complications such as bone fenestration and bone dehiscence. Hence, orthodontists should consider the patient's periodontal and dental condition during treatment and opt for a multidisciplinary approach when necessary to achieve optimal results.
This case report describes a successfully treated case of Class III malocclusion using an adjuvant therapy known as periodontally accelerated osteogenic orthodontics (PAOO). A 25-year-old man sought treatment primarily due to an evident anterior negative overjet. The patient was diagnosed with a skeletal Class III relationship and mandibular prognathism. A clinical examination revealed a severe Class III molar relationship and an anterior negative overjet. Moreover, cone-beam computed tomography revealed a thin labial bone plate in relation to the mandibular anterior teeth. The molar relation was corrected through molar distalization using miniscrews, and the mandibular incisors were retracted in conjunction with the PAOO procedure. Post-treatment outcomes demonstrated improved occlusal relationship, thickened labial bone plate of the mandibular anterior teeth, and absence of bone fenestration or dehiscence.
This clinical case shows that orthodontic treatment requires a multidisciplinary approach. The favorable results indicate that PAOO is effective in maintaining alveolar bone thickness and reducing the risk of periodontal complications.
正畸治疗存在潜在的风险和并发症，特别是当牙齿移动的路径超出牙槽骨范围，或者患者牙槽骨较薄时。这会增加患者发生骨开窗和骨开裂等并发症的风险。因此，正畸医生在治疗过程中应考虑患者的牙周和牙齿状况，并在必要时选择多学科治疗方法，以达到最佳效果。
本病例报告描述了一例成功应用牙周加速成骨正畸（PAOO）辅助治疗的 III 类错（牙合）畸形。一名 25 岁男性因明显的前牙反（牙合）就诊。患者被诊断为骨骼 III 类关系和下颌前突。临床检查显示严重的 III 类磨牙关系和前牙反（牙合）。此外，锥形束 CT 显示下颌前牙唇侧骨板较薄。通过微型种植体磨牙远移矫正磨牙关系，同时结合 PAOO 程序内收下颌切牙。治疗后结果显示，咬合关系得到改善，下颌前牙唇侧骨板增厚，无骨开窗或开裂。
本临床病例表明，正畸治疗需要多学科治疗方法。良好的治疗效果表明，PAOO 可有效维持牙槽骨厚度，降低牙周并发症风险。
