Impacted second molars can create problems with esthetics, masticatory function and dental arch stability. Treatment options include surgical extraction, surgical uncovering with orthodontic-assisted eruption and surgical uprighting.
The authors review the literature concerning surgical molar uprighting, and present a case in which the procedure was performed successfully to treat an impacted second molar in a female adolescent. The authors surgically repositioned a horizontal, right mandibular second molar that was partially impacted in bone. The patient was followed up for three years, during which time she was free of complications.
Surgical molar uprighting has been shown to be a predictable and reliable procedure. When a molar tooth is severely impacted, surgical uprighting provides a viable option when other treatment modalities are contraindicated.
阻生第二磨牙会引发美观、咀嚼功能及牙弓稳定性方面的问题。治疗选择包括外科拔除、正畸辅助萌出的外科开窗术以及外科直立术。
作者回顾了有关磨牙外科直立术的文献，并呈现了一例成功运用该手术治疗女性青少年阻生第二磨牙的病例。作者通过外科手术将水平位、部分骨内阻生的右下第二磨牙重新定位。对该患者进行了三年的随访，在此期间她未出现并发症。
磨牙外科直立术已被证明是一种可预测且可靠的手术。当磨牙严重阻生且其他治疗方式存在禁忌时，外科直立术提供了一种可行的选择。
