Abstract

Background: This study evaluated the clinical performance of posterior restorations made with direct and indirect composite materials.

Methods: In 74 participants, 79 class II cavities were restored using direct composite (Filtek Ultimate) and indirect composite (Crea.lign) materials. Indirect composite restorations were placed to cavity preparations when the isthmus width exceeded two-thirds of the intercuspal distance or teeth had a cuspal loss. Evaluations were conducted using modified World Dental Federation criteria during the first week and at 6 and 12 months. The data were analyzed statistically using Fisher's exact test and chi-square tests.

Results: After 12 months, 58 restorations were evaluated in 54 participants. None of the evaluation criteria showed significant differences between Filtek Ultimate and Crea.lign restorations (p > 0.05). At the 12-month, slight marginal discoloration was found in one Filtek Ultimate and two Crea.lign restorations (p > 0.05). Small marginal gaps were observed in two of the Crea.lign restorations. Post-operative sensitivity was detected within one week for six (13.9%) Filtek Ultimate and three (8.3%) Crea.lign restorations, with no significant difference between the two materials (p = 0.298).

Conclusion: At the 12-month evaluation, indirect and direct composite resin materials showed similar clinical performance. Crea.lign indirect composite material demonstrated acceptable clinical performance in large class II cavities, both with and without cuspal loss.

Trial registration: Retrospectively registered on NCT06667271. Data of registration: 30 October 2024.

直接和间接II类复合修复体的临床比较：一项前瞻性12个月随访研究。

背景：本研究评估了直接和间接复合材料后牙体修复的临床表现。方法：74例患者采用直接复合材料（Filtek Ultimate）和间接复合材料（Crea.lign）修复79个II类牙槽。当峡部宽度超过牙尖间距离的三分之二或牙尖缺失时，将间接复合修复体放置于腔体准备中。在第一周、第6个月和第12个月时，采用修改后的世界牙科联合会标准进行评估。采用Fisher精确检验和卡方检验对数据进行统计分析。结果：12个月后，54名受试者对58个修复体进行了评估。没有评估标准显示Filtek Ultimate和Crea之间有显著差异。牙体修复（p < 0.05）。在12个月时，在一个Filtek Ultimate和两个Crea中发现轻微的边缘变色。牙体修复（p < 0.05）。在两个Crea中观察到小的边缘间隙。所栽修复。6例Filtek Ultimate患者（13.9%）和3例Crea患者（8.3%）术后1周内检测到术后敏感性。两种材料间无显著性差异（p = 0.298）。结论：经12个月评估，间接复合树脂材料与直接复合树脂材料临床表现相近。克雷亚。木聚糖间接复合材料在有或没有牙尖缺失的大II类牙槽中表现出可接受的临床性能。试验注册：回顾性注册编号NCT06667271。登记日期：2024年10月30日。
