To evaluate the clinical application value of minimal prepared ceramic veneer in anterior teeth, by analyzing the esthetic effects and success rates.
Forty-four anterior teeth in 30 patients with minor esthetic defect were included in this study. Less than 0.5 mm preparation or no preparaion technique was used in the clinical procedure. Glass ceramics veneers were delivered and 3M Relyx Veneer were used as the adhesive. The final appearance of each restoration was evaluated by patients on visual analogue scales (VAS) and by professional prosthodontists. Evaluation criteria included margin effects, color, shape and translucency. The success rate of all the restoration were analyzed in 6, 12 and 24 month after the treatment.
The patients' degree of satisfaction was 9.2 ± 0.4, while the excellent rate of esthetic effect of margin effect, color, shape and translucency was 89% (39/44), 91% (40/44), 98% (43/44) and 93% (41/44) by professional prosthodontist. The success rate of 6, 12 and 24 month were 100% (44/44), 98% (43/44) and 91% (40/44).
The minimal prepared venneers have a good esthetic effect and a satisfactory success rate, and is a suitable technique in esthetic treatment under the critical indications.
通过分析美学效果和成功率，评估微创预备陶瓷贴面在前牙的临床应用价值。
本研究纳入30例存在轻微美学缺陷患者的44颗前牙。临床操作采用小于0.5mm预备或无预备技术。采用玻璃陶瓷贴面，并使用3M Relyx Veneer作为粘接剂。由患者通过视觉模拟量表（VAS）以及专业口腔修复医生对每个修复体的最终外观进行评估。评估标准包括边缘效果、颜色、形态和透明度。在治疗后6个月、12个月和24个月分析所有修复体的成功率。
患者满意度为9.2±0.4，专业口腔修复医生对边缘效果、颜色、形态和透明度美学效果的优良率分别为89%（39/44）、91%（40/44）、98%（43/44）和93%（41/44）。6个月、12个月和24个月的成功率分别为100%（44/44）、98%（43/44）和91%（40/44）。
微创预备贴面具有良好的美学效果和令人满意的成功率，是在严格适应证下美学治疗的一种合适技术。
