It is well-recognized that excessive gingival display can have a negative impact on a patient's smile. Excessive gingival display due to gingival enlargement or altered passive eruption (dentogingival cause) can be corrected effectively through periodontal surgeries. This article describes two successful esthetic crown-lengthening surgeries that were guided by an acetate template to better predict the outcomes of the surgical procedures in relation to the symmetry and harmony of the gingival contour. This article also highlights the importance of utilizing an interdisciplinary approach to obtain an optimum esthetic result for restorative treatments in the anterior maxilla.
众所周知，牙龈过度外露会对患者的笑容产生负面影响。由于牙龈肿大或被动萌出改变（牙-牙龈原因）导致的牙龈过度外露可以通过牙周手术有效矫正。本文描述了两例成功的美学牙冠延长手术，该手术由醋酸酯模板引导，以便更好地预测手术结果与牙龈轮廓的对称性和协调性之间的关系。本文还强调了采用多学科方法为上颌前部修复治疗获得最佳美学效果的重要性。
