Becker's nevus is a relatively common skin lesion with brown hyperpigmentation and hypertrichosis. It may be expressed simultaneously with other cutaneous, muscular, or skeletal defects, such as hypoplasia of the breast or scoliosis, for which the term "Becker's nevus syndrome" has been proposed. An 8-year-old boy presented with a Becker's nevus on the right cheek, chin, and upper neck with alveolar bone hypertrophy in the anterior mandible, which led to an anterior crossbite and severe canting of the mandibular anterior teeth. Through orthopedic treatment using a face mask, the anteroposterior jaw relationship was improved. In phase 2 treatment, we corrected the canting of the mandibular anterior teeth with a segmental intrusion of the mandibular anterior right teeth into the hypertrophic alveolar bone area. The facial profile was improved along with acceptable occlusion, and the treatment result was stable at 1 year after the end of the treatment, without any periodontal attachment loss, root resorption of mandibular anterior teeth, or increase in the size of the hypertrophic region. This case report describes the successful comprehensive treatment of a growing patient with skeletal Class III malocclusion and multiple characteristics of Becker's nevus syndrome.
贝克痣是一种相对常见的皮肤损害，伴有褐色色素沉着和多毛症。它可能与其他皮肤、肌肉或骨骼缺陷同时出现，如乳房发育不全或脊柱侧弯，为此有人提出了“贝克痣综合征”这一术语。一名8岁男孩右侧脸颊、下巴和上颈部出现贝克痣，同时下颌前部牙槽骨肥大，导致前牙反合和下颌前牙严重倾斜。通过使用面罩进行正畸治疗，改善了前后颌关系。在第二阶段治疗中，我们通过将下颌右侧前牙分段压入肥大的牙槽骨区域来纠正下颌前牙的倾斜。面部轮廓得到改善，咬合良好，治疗结束1年后治疗效果稳定，没有出现任何牙周附着丧失、下颌前牙根吸收或肥大区域增大的情况。本病例报告描述了对一名患有骨骼Ⅲ类错牙合畸形且具有贝克痣综合征多种特征的生长发育期患者进行成功综合治疗的过程。
