以人工牙貼片製作暫用牙橋之臨床應用－病例報告
The Provisional Bridge Fabricated with Artificial Teeth-Case Report
摘要
臨床上，暫用牙橋變色常會造成美觀受影響，尤其是在前牙美觀區。當患者因治療而必須長期裝戴暫用牙橋時，暫用牙橋顏色的穩定與光澤對於美觀的增進成為臨床上不可忽視的重要課題。 本病例為年輕男性，原有的前牙陶瓷補綴物破折，要求重新製作。經X光檢查病人前牙係非活性齒，雖經根管治療，仍有根尖X光可透區病灶，因此建議患者重新進行根管治療。整個治療時間會因而延長，且患者對美觀又極為重視，為避免暫用牙橋變色，決定採用人工牙貼片來製作暫用牙橋。此一臨床應用，在治療期間暫用牙橋並無發生變色的問題，患者對於美觀也相當滿意。對於治療計畫中需要長期裝戴暫用牙橋的患者，可以利用人工牙貼片來製作暫用牙橋，以提升美觀達患者的要求，且可避免暫用牙橋發生變色的問題。提出此病例，僅供牙醫師臨床上選擇製作之參考。

Discoloration of provisional bridge can be an esthetic problem, especially in the esthetic zone and when the treatment plan requires long-term provision because of periodontal problems or endodontic treatment. Therefore, color stability and brightness of provisional bridge is an important topic that should not be neglected. This report presents a case of a young male patient. He wanted to have a new fixed prosthesis of upper anterior teeth due to the old one have been ill-fitted and the porcelain had long since fractured. After clinical and radiographic examination, we found that the abutment teeth had incomplete endodontic treatment. We suggested the patient have re-endodontic treatment before new prosthesis was fabricated. Owing to the long treatment period and the patient taking esthetics seriously, we decided to fabricate provisional bridge by use of artificial teeth to avoid discoloration of the provisional bridge. During the treatment period, discoloration did not occur and the patient was well satisfied with esthetics. This treatment method of a provisional bridge being fabricated by use of artificial teeth can be applied to patients who must wear provisional bridge for extended periods to avoid discoloration of such bridge.
