COMPARATIVE ANALYSIS OF CEMENT PROPERTIES FOR FIXING VENEERS

Abstract

The natural beauty of teeth makes certain demands on dental materials and treatment methods.
One of the most popular methods of treatment of dental fluorosis recently is orthopedic treatment – the use of veneers, which have significant advantages over other types of restoration. Veneers give the tooth the most natural aesthetic appearance and restore the crown of the tooth to its original strength. And also veneers are translucent, so you can achieve a natural appearance even with ultraviolet radiation.
Aim. We set the task – to study the physicomechanical properties of these blocks of cement, in particular, to determine the film thickness of each cement when fixing various orthopedic structures, including veneers.
Materials and methods. The laboratory study of the studied blocks of cement was carried out in accordance with the recommendations of the international ISO standard. All samples were fabricated at t 23+10C and relative humidity 50+10 %.
Cement mixing was carried out strictly according to the manufacturer's instructions. The quality of each cement was evaluated by film thickness and cement adhesion (tooth-construction).
Conclusions. To fix the veneers used for the treatment of cosmetic treatment and tooth fluorosis, the following blocks of cement were selected: RelyXTM ARC from 3M ESPE, Bifix DС from Voco, Cemion.
The blocks of cement we studied in terms of film thicknesses of cement from different companies meet the requirements of the International Standard ISO and can be used for permanent fixation of veneers (RelyXTM ARC from 3M ESPE, as well as prostheses of other designs (Bifix DC, Cemion).
