摘要
微笑所呈现的唇齿龈三者关系、牙齿形状以及显露的牙龈形态是形成口腔医学美学中“红白美学”的主要要素。相对于天然牙齿而言，由游离龈、附着龈和龈乳头等软组织构成的“红色美学”越来越受到人们重视。牙龈的健康状况及其位置、形态、质地，牙龈与临床牙冠的形态协调性是衡量前牙美学修复成功与否的重要标志。
A young lady with unsatisfied restorations of upper anterior teeth and swollen gum wanted to improve aesthetics. Oral examination showed that 12-22 were provisional crowns with normal occlusion, poorly gingival contour and gummy smile. The gingiva was red, light swollen and bleeding on probing. X-ray showed the roots of 11,21 were short and the alveolar bone absorbed. After the periodontal initial treatment, an ideal location of gingival margin was determined. Then, an esthetic periodontal surgery was performed to recover the biology width and the gingival margin was fitted with the anterior teeth. The tem-porary restorations were made twice to guide the gingiva growth by changing the shape of the restorations and moving up the contact points of the restorations. The ceramic crowns were completed 3 months after the operation. The gummy smile disappeared and the gingival margin was filled well with the upper ante-rior ceramic crowns. The 14-month follow-up presented a satisfied effect. Crown lengthening surgery com-bined restorative therapy could lead papilla to grow well. This process is beneficial for the future treat- ment plan and clinical esthetic evaluation.
