The objective in this case report is to present a correction of excessive gingival exposure performed through periodontal esthetic surgery, using clinical crown lengthening and lip repositioning. The patient reported discomfort when smiling due to excessive gingival exposure, and clinical and photographic examinations of the patient showed vertical maxillary growth as the main diagnosis. In the digital smile design, the possibility of crown lengthening observed for teeth - upper left and right central incisors and upper left lateral incisor. A lip-repositioning procedure was also planned. An incision was performed at the mucogingival junction, and a parallel incision was realized at the top of the alveolar mucosa. Afterward, the incised gingival band was removed through vertical incisions in the planned border area. The muscular area was preserved. A simple suture was made, with the approach of the gingival margins around the surgical area. The crown-lengthening procedure was performed with the flapless technique. After 2-year follow-up, the periodontal esthetic surgery, comprising crown lengthening and lip repositioning, was noninvasive and can thus serve as an interesting alternative treatment for excessive exposure of the gingival smile, as it results in a harmonious and natural smile.
本病例报告的目的是介绍通过牙周美学手术进行的过度牙龈暴露矫正，采用临床牙冠延长术和唇部重新定位术。患者因牙龈过度暴露在微笑时感到不适，对患者的临床和照片检查显示，主要诊断为上颌垂直生长。在数字化微笑设计中，观察到左上、右上中切牙和左上侧切牙有牙冠延长的可能性。还计划进行唇部重新定位手术。在膜龈交界处做切口，并在牙槽黏膜顶部做平行切口。然后，通过在计划边界区域的垂直切口切除切开的牙龈带。保留肌肉区域。进行简单缝合，使手术区域周围的牙龈边缘靠近。采用无瓣技术进行牙冠延长术。经过2年的随访，包括牙冠延长术和唇部重新定位术在内的牙周美学手术是非侵入性的，因此可以作为治疗牙龈微笑过度暴露的一种有趣的替代治疗方法，因为它能带来和谐自然的微笑。
