摘　　要：目的　比较复合树脂暂冠材料与常规的化学固化丙烯酸树脂暂冠材料 (自凝塑料 )临床操作和修复效果 ,为临床应用提供参考。方法　共 93例门诊固定修复患者 ,4 4例患者应用复合树脂暂冠材料制作暂冠 ,共 1 5 3个单位 ,前牙 91个单位 ,后牙 6 2个单位 ;4 9例患者应用丙烯酸树脂材料 (自凝塑料 )制作暂冠 ,共 1 4 4个单位 ,前牙86个单位 ,后牙 5 8个单位。复诊时间 1周至 3周。采用美国加利福尼亚牙科学会的质量评价体系 ,结合对患者问卷调查 ,对两种暂冠修复材料的临床应用进行比较。结果　应用复合树脂暂冠材料制作的暂冠表面光洁 ,抛光度高 ,边缘完整密合 ,形态还原性好 ,牙龈健康状态良好 ,患者口感较好 ,异味较小 ,食物嵌塞少。Objective\ The purpose of this study was to compare the clinical application and effect of two temporary restorations materials : composite and self_cured acrylic resin.Methods\ 153 composite temporary crowns (and bridges) placed in 44 patients and 144 self_cured acrylic resin temporary crowns (and bridges) placed in 49 patients were evaluated according to the California Dental Association′s (CDA) criteria and questionnaire.Results\ It showed that composite temporary crowns (and bridges) had better surface smoothness, marginal integrity and anatomic form than self_cured acrylic resin temporary crowns (and bridges). In the 49 patients with self_cured acrylic resin temporary crowns (and bridges), 67% and 88% of them complained of food impaction and mouth odor, while only 2% and 30% in the 44 patients with composite temporary crowns (and bridges) had the same complaint.Conclusion\ Between the two temporary restoration materials, composite is better than self_cured acrylic resin.\;
