This study determined the feasibility of saucer-shaped cavity preparations for composite resins in class II lesions. Saucer-shaped class II cavity preparations were restored with composite resin and subjected to clinical, radiographic, and replica cast evaluation (39 restorations) after 6, 18, and 36 months. The results indicated that the retention, resistance form, and wear resistance of the class II saucer-shaped cavity preparations were satisfactory after 3 years.
本研究确定了Ⅱ类洞形采用碟形洞预备复合树脂修复的可行性。对Ⅱ类碟形洞预备体用复合树脂进行修复，并在6个月、18个月和36个月后进行临床、影像学和复制模型评估（共39个修复体）。结果表明，3年后Ⅱ类碟形洞预备体的固位、抗力形和耐磨性均令人满意。
