CAD/CAM全瓷固定修復體臨床效果評價
Clinical evaluation of all-ceramic prosthetic restoration made by CAD/CAM
摘要
目的：對CAD/CAM三種全瓷修復體的修復效果進行探討，為臨床應用提供參考。方法：對兩年內澳門鏡湖醫院口腔科收治的76例接受全瓷修復的患者，採用CAD/CAM技術製作包括嵌體、單冠、貼面全瓷修復體共86例，分別在修復體黏結後對患者進行隨訪觀察，採用美國加州牙科協會的全瓷修復臨床標準對修復體的臨床效果進行評價。結果：在（1.6±0.5年）的平均觀察期內，有13例修復體邊緣卡探針，3例修復體出現完全折裂或脫落，12例修復體有咬合但恢復不足，2例修復體鄰面觸點恢復不佳，44例修復體的顏色匹配稍差，6例修復體有輕微牙齦炎，13例修復體出現食物輕度嵌塞。在觀察期內，失敗的修復體各項指標比較差異均有統計學意義（P<0.05），還不能認為臨6種床評價內容之間有差別。結論：CAD/CAM製作的修復體具有良好的穩定性和生物相容性，近期臨床效果滿意。

Objective: To investigate the clinical effect of three kinds of all-ceramic prosthetic restoration which were made by computer-aided design and computer-aided manufacturing (CAD/CAM) techniques as future clinical reference. Methods: CAD/CAM techniques were used to make all-ceramic restoration including inlay, single crown and veneer for 86 teeth on 76 patients in 2 years of follow-up. The clinical efficacy of the restorations was evaluated by American Dental Association of California clinical standard. Results: Slight margin discrepancy was observed in 13 restorations. Fracture was registered in 3 cases. Twelve restorations had no adequately restored occlusion. The adjacent surface contacts were not restored well in2 cases. Forty-four restorations had a slight mismatch in color. Gingival inflammation was observed in 6restorations. Food impaction was found in 13 restorations. Evidence of decay was observed. No significant difference was observed in 6 kinds of clinical evaluation in the average observation period of (1.6±0.5)years. Conclusion: The clinical outcome of the restorations is favorable. CAD/CAM techniques seem to be a reliable treatment option.
