Abstract

The aim of this study was to determine the performance of an experimental all-in-one adhesive. The adhesive, named MTB-200 (Kuraray Medical), contained components to enhance both bond strength and hydrophobicity. The performance of the adhesive was compared with that of CLEARFIL TRI-S BOND (Kuraray Medical) and BeautiBond (SHOFU) using micro-tensile bond strength test and ultramicroscopic observations. The study revealed that the new adhesive had the highest tensile strength value among the three adhesives over time, although transmission electron microscopic images showed the phenomenon of filler de-bonding in the adhesive resin layer. In spite of modification in the experimental adhesive, the adhesive was suspected to degrade bond performance. However, revision of the composition of adhesives would be one of the solutions to enhance durability of interface.

摘要

本研究的目的是测定一种实验性一体化粘合剂的性能。这种名为MTB - 200（可乐丽医疗株式会社）的粘合剂含有增强粘结强度和疏水性的成分。使用微拉伸粘结强度测试和超微观观察，将该粘合剂的性能与可乐丽医疗株式会社的CLEARFIL TRI - S BOND以及松风公司的BeautiBond进行了比较。研究表明，随着时间推移，这种新型粘合剂在三种粘合剂中具有最高的拉伸强度值，尽管透射电子显微镜图像显示粘合剂树脂层中存在填料脱粘现象。尽管对实验性粘合剂进行了改性，但仍怀疑该粘合剂会降低粘结性能。然而，修改粘合剂的成分将是提高界面耐久性的解决方案之一。
