Abstract

In addition to affecting oral functions such as temporomandibular joint function, mastication, and speech, malocclusion caused by skeletal maxillary prognathism also entails sociopsychological implications. Surgical orthodontic treatment to improve occlusion and oral function and to correct esthetic disharmony is important to improve patients' quality of life. We report the case of a 32-year-old woman who visited our hospital with a chief complaint of proclined upper front teeth. Clinical examination revealed maxillary overgrowth and severe labial inclination of the maxillary incisors with palatal gingival recession. The incisal protrusion was corrected with a maxillary anterior alveolar osteotomy-a surgical orthodontic method that could improve the overbite without causing excessive lingual inclination, while also minimizing orthodontic movement of the maxillary anterior teeth. This treatment is generally indicated in cases of maxillary prognathism with a relatively stable occlusal relationship in the molar region. As a result of the treatment, the patient's chief complaint improved and a long-term functional occlusion was achieved. This paper outlines the pre- and posttreatment skeletal and occlusal changes.

上颌前牙槽截骨术治疗上颌前突伴严重过咬合。
除了影响颞下颌关节功能、咀嚼和言语等口腔功能外,上颌骨前突引起的错颌畸形还会对社会心理产生影响。通过外科正畸治疗来改善咬合和口腔功能,纠正美观上的不协调,对于提高患者的生活质量非常重要。我们报告了一例 32 岁女性的病例,她来我院就诊的主诉是上前牙突出。临床检查发现她的上颌过长,上颌切牙唇侧严重倾斜,腭侧牙龈退缩。我们采用了上颌前牙齿槽截骨术来矫正切牙前突--这是一种外科正畸方法,既能改善咬合过度,又不会造成舌侧过度倾斜,同时还能最大限度地减少上颌前牙的正畸移动。这种治疗方法一般适用于臼齿区咬合关系相对稳定的上颌前突病例。治疗后,患者的主诉得到了改善,并实现了长期的功能性咬合。本文概述了治疗前后骨骼和咬合的变化。
