Comparative Evaluation of Wettability of Conventional Vs Cad/Cam Denture Base Resins

Abstract

Introduction:

In edentulous patients, the replacement of lost teeth and tissues with a complete denture to obtain an acceptable esthetic and function seems to be a challenge for the dentist.The success of a complete denture is based on the degree of retention and stability of the prosthesis.

Aim:

The aim of the study was to compare the wetting properties of conventional and CAD/CAM bases denture base resins by artificial saliva substitute by using contact angle measurements.

Method:

Three denture base materials were selected: CAD/CAM denture base material (Group A - Milled resin, Group B - 3D printed resin) and BPS (Group C) denture material. A total of 30 samples were used for each group in the study.  The advancing and receding contact angles with artificial saliva (experiment group) and distilled water (control group) were measured with a goniometer. The contact angle hysteresis was also calculated from the advancing and receding contact angles values.
