Evaluation of restoration bonding systems using microtensile bond strength tests and finite element analysis
Laboratory bond strength measurement is a widely used method of evaluating commercial dentine bonding systems and predict their clinical performance. Therefore, a thorough understanding of the stress patterns involved in bond failure is an important factor in evaluating usefulness of a specific bond strength testing method. Different specimen designs are used in the microtensile bond strength testing method; these are stick, dumbbell and hourglass shape. However, so far little attention has been paid to the details of methodology of the test procedures used. The aim of this study is to compare three dentine bonding systems utilizing three experimental microtensile bond strength test designs (µTBS) and correlating the outcomes with finite element stress analysis (FEA).
