This case report describes the treatment of a case involving a skeletal Class II facial profile with a gummy smile. While treating a facial profile and a gummy smile, the outcome may not always be successful with orthodontic therapy alone. For this reason, surgical therapy is often chosen to gain an esthetic facial profile and a good smile. However, sometimes the patients reject surgical treatment and an alternative method must be considered. Skeletal anchorage systems such as miniscrews are now frequently used for correcting severe malocclusion that should be treated by surgical therapy. In this case report, we treated a skeletal Class II malocclusion with a convex profile and a gummy smile using miniscrews, which were placed in the upper posterior and anterior areas. The active treatment period was 3.5 years, and the patient's teeth continued to be stable after a retention period of 36 months.
本病例报告描述了一例骨性 II 类面型伴露龈笑患者的治疗过程。在治疗面型和露龈笑时,单纯的正畸治疗结果并不总是成功的。因此,通常选择手术治疗来获得美观的面型和良好的笑容。然而,有时患者会拒绝手术治疗,此时必须考虑替代方法。骨骼锚固系统(如微螺钉)现在常用于矫正需要手术治疗的严重错颌畸形。在本病例报告中,我们使用微螺钉治疗了一例骨性 II 类错颌伴凸面型和露龈笑的患者,微螺钉分别植入上颌后区和前区。主动治疗期为 3.5 年,在 36 个月的保持期后,患者的牙齿仍保持稳定。
