Research Abstract

The Dentist checks junction between the tooth and the crown or inlay. These are contaminated with saliva or blood at this time. Contamination is not lost even if it performs sufficient rinsing. Zirconia is the optimal material for the restoration of a beautiful tooth in dental treatment. It is important to carry out the chemical reaction between adhesives and zirconia in order to bond up zirconia and tooth. However, adhesives cannot carry out the chemical reaction of the contaminated zirconia surface easily. The new adhesion method which can solves these problems was developed.
