摘要

本病例為廣泛性中度慢性牙周炎，合併右側後方過度萌出及咬合喪失；美觀上有微笑露齦，臨床牙冠比例不佳，下顎右側門牙舌側異位等問題。經牙周基本治療後，藉由人工植體手術、輔助性矯正、牙冠增長術、最終補綴復：重建咬合功能及改善美觀。人工植體的臨床運用除了解決缺牙問題，當病患有矯正需求時也是有效的錨定（anchorage）。過多的牙齦暴露是美觀的一大顧慮，牙冠增長術可改變牙冠寬長比例，也是改善微笑露齦的手段之一，術前仔細評估牙齦過度暴露因素，才能建立牙齦健康的生物條件。

This is a case of generalized chronic periodontitis with occlusal problems which include the loss of right posterior occlusion and supraeruption of the right upper posterior teeth. The patient is presented with a gummy smile and an improper crown ratio which impairs esthetics. Through basic periodontal treatment, the periodontal tissue health improved significantly. A series of further treatment, implant surgery, adjunctive orthodontic treatment, and surgical crown lengthening, was done to restore function and esthetics for the patient. Dental implants not only restore the missing teeth, but also serve as an efficient anchorage in case orthodontic treatment is needed. Excess gum display is also a concern for esthetics. Crown lengthening can alter the width-to-height ratio, and serve as a measure to improve the patient's gummy smile. A thorough assessment of the cause of a gummy smile is mandatory prior to surgery to establish a biological requirement for periodontal health.
