摘要

上顎前牙區的重建向來被視為充滿挑戰性的任務，主因在其深深影響美觀及社交，因此病患對於此區的治療期待相較於口內其他位置無法等量齊觀，藉由數位微笑設計可分析病患現況及模擬理想微笑曲線，調整出醫病雙方具共識之型態，平衡兩者對治療期待之差距；而透過雷射輔助牙周整形手術的進行，可因雷射能量產生的吸收特異性，獲得術後更穩定的成果及外觀，對於美觀區的治療有極大的幫助。本病例為一34歲女性，透過數位微笑分析設計理想微笑曲線，並使用鉺雅鉻雷射輔助牙冠增長術進行，最終製作全瓷冠及陶瓷貼片達成美觀性及功能性的重建，術後追蹤成果穩定。

Rehabilitation of upper anterior region is a challenging mission due to the influence of esthetics and social activity. Therefore, The patient's treatment expectation of this area could not be on a par with any other intraoral area. Digital smile design is a concept of analyzing the oral condition and simulating the result. It can visualize the smile design via software, to facilitate a discussion between dentists and patients before establishing final treatment decision. With the application of laser in periodontal plastic surgery, the stability of soft tissue margin and esthetic outcome are more predictable. In this report, we present a case reconstruction upper anterior gingival level and discolored teeth with all-ceramic crown and porcelain veneer through digital smile design and Er: YAG laser assisted crown lengthening surgery.
