Enabling Standardization in Shear Bond Strength Tests for Orthodontic Adhesives on Natural Teeth by Using an Innovative Grip Accessory for the Testing Machine

Article Preview

Abstract:

Shear Bond Strength testing is one of the most common used tests for Orthodontics Adhesives. However, the standardizations of such procedures is quite difficult due to a large number of factors. While scientists are designing their studies in order to reduce errors, sometime they may find themselves in front of technical difficulties. A custom device was developed in order to allow a testing procedure that is closer to in vitro conditions. The device, mounted on a material testing machine permits sample inclination to a degree that reduces tensile component to the shear stress, therefore more accurate readings of the values are available and standardization of shear bond testing procedures is more probable.
