運用牙冠增長術及軟組織增進術於上顎前牙牙橋-病例報告

Surgical Crown Lengthening and Soft Tissue Augmentation at the Maxillary Anterior Bridge- A Case Report

摘要


當牙齒齲齒範圍過大時,拔牙並以人工植牙重建缺牙區已成為普遍選項之一。前牙缺失後常見嚴重軟硬組織萎縮,而植牙前缺損殘的重建常要多次手術介入並需較多的治療費用與時間。患者接受此類治療時亦需克服恐懼且有更多的認知與配合。適當情況下,以牙冠增長術保留現存牙根並以傳統牙橋復形,不失為另一經濟快速之治療選項。相較於固定植牙復物,傳統牙冠牙橋具有簡單、經濟、快速修復、治療時間較短等優點。本病例報告描述一30歲男性患者,因長期缺牙及深度齲齒導致舊假牙不密合且美觀不佳。藉由牙冠增長術合併結締組織移植與適當補綴物設計達成美觀及功能之治療結果。

Replacing an extensively decayed tooth with a dental implant has become a popular treatment option. Severe hard and soft tissue atrophy, however, is common in the anterior edentulous region.Prior to implant installation, multiple surgeries are often mandatory in reconstructing deficient alveolar ridge, which result in higher cost and longer treatment period. Patients need to overcome their fear of such treatment modality, and require more recognition as well as cooperation. On the other hand, in suitable scenarios, preservation of the existing root through crown lengthening procedures, followed by conventional crown or bridge fabrication, may be another economical and time-saving treatment option. Conventional crown and bridge has advantages of simple, inexpensiveness, quick repair, and less treatment time. This case report demonstrates a 30-year-old male who suffered from an ill-fitting and unsightly bridge due to prolonged edentulism and deep caries. Surgical crown lengthening procedures, ridge augmentation using a connective tissue graft, and proper prosthetic design contributed to the esthetic and functional treatment outcome.
