Abstract

Aim

This study aimed to investigate the impact of different cement and cement isolation techniques used in implant-supported restorations on eliminating residual cement.

Materials and Methods

This study employed two distinct cement isolation methods: rubber dam and polytetrafluoroethylene tape. The study comprised three primary groups comprising 30 samples, categorized based on the isolation methods and control group. The cement excess was removed with a dental explorer probe for the control group. Moreover, three different cement materials were used: polycarboxylate, temporary implant, and resin cement. Each primary group was subdivided into three subgroups according to the type of cement used, leading to 10 samples per subgroup. Cobalt-chromium superstructures, intended to be cemented onto the implant analog-abutment complex, were fabricated using the direct metal laser sintering method. The crowns were filled with cement, and after the cementation process, any excess cement was subsequently removed using the designated isolation method. After removal, images of the cement residues at the gingival margin of the crown-abutment complex and occlusal surface of the gingiva around the implant were captured. These images were then analyzed using Adobe Photoshop CC2018, wherein excess cement was marked using the Lasso Tool to quantify the total area. The excess cement data was analyzed using IBM SPSS Statistics Version 23 software.

Results

The results of the three-way ANOVA showed a difference in excess cement amounts between the isolation methods and cement materials (p < 0.001). In evaluating the isolation methods, the rubber dam was identified as the most suitable for temporary cement, while polytetrafluoroethylene tape was determined as the most suitable method for resin cement. Using a dental probe resulted in the highest amount of residual cement across all cement materials. Among the cement types, polycarboxylate cement exhibited the highest residual cement amount, followed by temporary implant cement and resin cement.

Conclusions

The amount of excess cement was influenced by the isolation method and the type of cement used. The rubber dam emerged as the most effective method for minimizing cement residues. The most significant amount of residual cement was identified for polycarboxylate, whereas the lowest amount was observed for resin cement. The appropriate isolation method should be selected based on the type of cement.

水泥材料的选择及有效去除胶结中残余水泥的隔离技术
目的探讨种植体支持修复体中不同的骨水泥和骨水泥隔离技术对消除残余骨水泥的影响。材料和方法本研究采用两种不同的水泥隔离方法:橡胶坝和聚四氟乙烯胶带。本研究包括三个主要组,共30个样本,根据分离方法和对照组进行分类。对照组用牙探针去除多余的水泥。此外,还使用了三种不同的水泥材料:聚羧酸盐、临时种植体和树脂水泥。每个初级组根据所使用的水泥类型再细分为三个亚组,每个亚组10个样品。采用直接金属激光烧结方法制备钴铬超结构,并将其粘合到种植体模拟基牙配合物上。在冠内填充水泥,在胶结过程结束后,使用指定的隔离方法去除多余的水泥。去除后,采集冠-基牙复合体牙龈边缘和种植体周围牙龈咬合面的骨水泥残留图像。然后使用Adobe Photoshop CC2018对这些图像进行分析,其中使用套索工具标记多余的水泥以量化总面积。使用IBM SPSS Statistics Version 23软件对过量水泥数据进行分析。结果三因素方差分析结果显示,隔离方法和水泥材料在过量水泥量方面存在差异(p < 0.001)。在评价隔离方法时,橡胶坝是最适合临时水泥的方法,聚四氟乙烯胶带是最适合树脂水泥的方法。使用牙科探针导致所有水泥材料中残留水泥量最高。其中,聚羧酸盐水泥残留量最高,其次是临时种植体水泥和树脂水泥。结论固井方法和固井类型对固井过量量有影响。橡胶坝成为减少水泥残留最有效的方法。聚羧酸盐的残余水泥量最大,而树脂水泥的残余水泥量最低。应根据水泥的种类选择合适的隔离方法。
