Peg-shaped lateral incisors are the most prevalent tooth size discrepancy, which can have a number of functional and aesthetic implications in affected people. This case report presents a conservative treatment approach to treat bilateral peg laterals and restore aesthetic harmony. A 21-year-old male patient complained about the shape and unaesthetic appearance of his two front teeth which negatively impacted his smile. The patient presented with bilateral peg laterals in the maxillary arch, and he had a stable occlusion with normal overjet and overlap and good periodontal health. Digital smile design (DSD) analysis revealed a discrepancy in crown width between Teeth #13 and #23 and gingival height discrepancy between Teeth #11 and #21, and #12 and #22. Accordingly, it was planned to perform a crown lengthening procedure to overcome the gingival height discrepancy of Teeth #12 and #21, place a full-contour resin composite restoration on Teeth #12 and # 22 and increase the mesiodistal width of Tooth #13. The patient underwent home teeth whitening for 2 weeks, followed by a 1-week observation period to ensure colour stability of the tooth. Laser gingivectomy was performed to correct the gingival height discrepancy, and incremental resin composite was used to restore the peg-shaped laterals. The restoration was contoured, finished and polished to obtain a smooth and glossy finish. The aesthetic treatment achieved excellent results, and the patient was pleased and excited with his new smile.
钉状侧切牙是最常见的牙齿大小差异，这可能会对受影响的人产生许多功能和美学方面的影响。本病例报告介绍了一种保守的治疗方法，用于治疗双侧钉状侧切牙并恢复美学和谐。一名21岁男性患者抱怨他的两颗前门牙的形状和不美观外观对他的笑容产生了负面影响。患者上颌牙弓双侧为钉状侧切牙，咬合稳定，覆盖和覆合正常，牙周健康良好。数字微笑设计（DSD）分析显示13号牙和23号牙之间的冠宽存在差异，11号牙和21号牙以及12号牙和22号牙之间的牙龈高度存在差异。因此，计划进行牙冠延长术以克服12号牙和21号牙的牙龈高度差异，在12号牙和22号牙上放置全冠树脂复合材料修复体，并增加13号牙的近远中宽度。患者进行了为期2周的家庭牙齿美白，随后进行了1周的观察期以确保牙齿颜色稳定。进行激光牙龈切除术以纠正牙龈高度差异，并使用增量树脂复合材料修复钉状侧切牙。对修复体进行塑形、修整和抛光以获得光滑有光泽的表面。美学治疗取得了优异的效果，患者对他的新笑容感到满意和兴奋。
