问题的陈述。需要客观的长期临床数据来评估现代后牙复合材料作为直接外皮间接修复体的性能。目的。这项前瞻性、长期临床试验评估了直接和间接复合修复体作为单表面或多表面腔体后牙修复体的临床可接受性，并提供了 3 年结果的调查。材料和方法。在经验丰富的牙医的监督下，9 名牙科学生放置了 88 个复合修复体（Tetric、blend-a-lux、Pertac-Hybrid Unifil）、43 个直接复合修复体和 45 个间接嵌体。由另外 2 名经验丰富的牙医使用修改后的 USPHS 标准在基线和安置后每年进行临床评估。安置后 33 至 36 个月内对 60 个修复体进行了第三次随访。结果。总共 93% 的间接修复体和 87% 的直接修复体被评估为临床优秀或可接受。第三年，1 例磨牙直接修复因边缘开口而失败。间接嵌体比直接复合修复体表现出明显更好的表面解剖形态。前磨牙的边缘完整性和表面解剖形态明显优于磨牙。与前磨牙相比，磨牙修复体的失败率明显更高。结论。后牙复合修复体提供了令人满意的临床表现：在 3 年的时间内，即使放置在相对缺乏经验但受到监督的学生中也是如此。
Statement of the problem. Objective long-term clinical data are necessary to assess the performance of modern posterior composites as direct rind indirect restorations.Purpose. This prospective, long-term clinical trial evaluated direct and indirect composite restorations For clinical acceptability as posterior restoratives in single or multisurface cavities and provided a survey on the 3-year results.Material and methods. Under the supervision of an experienced dentist, 9 dental students placed 88 composite restorations (Tetric, blend-a-lux, Pertac-Hybrid Unifil), 43 direct composite restorations, and 45 indirect inlays. Clinical evaluation was performed at baseline and in yearly intervals after placement by 2 other experienced dentists, using modified USPHS criteria. A third Follow-up of 60 restorations took place within 33 to 36 months after placement.Results. A total of 93% of indirect and 87% of direct restorations were assessed to be clinically excellent or acceptable. During the third year, 1 direct restoration in a molar failed because of margin opening. Indirect inlays exhibited a significantly better anatomic form of the surface than direct composite restorations. Premolars revealed a significantly better marginal integrity and anatomic form of the surface than molars. Restorations in molars exhibited a significantly higher failure rate compared with premolars.Conclusion. Posterior composite restorations provided a satisfactory clinical performance: over a 3-year period, even if placed hy relatively inexperienced but supervised students.
