A gummy smile poses a restorative challenge for dentists attempting to achieve ideal esthetics. Many have advocated the use of a gingivectomy or laser-assisted gingival contouring procedure. However, this simplistic approach can potentially create a mucogingival defect or a biological width violation. To avoid these periodontal-restorative complications, it is important during treatment planning to assess the anatomical relationship that resulted in the gummy smile and choose the appropriate surgical treatment to eliminate this condition.
露龈笑给试图实现理想美学效果的牙医带来了修复方面的挑战。许多人主张采用牙龈切除术或激光辅助牙龈成形术。然而，这种简单的方法可能会导致膜龈缺损或生物学宽度破坏。为避免这些牙周修复并发症，在治疗计划过程中评估导致露龈笑的解剖学关系并选择合适的手术治疗方法以消除这种情况非常重要。
