Surface Roughness of Heat Cured Acrylic Resin Versus Acrylic Resin With Titanium Dioxide

Study Overview
=================
Brief Summary
-----------------
Measurement of surface roughness of tow different material of denture base to find out which material is more hygienic by decreasing the amount of bacterial accumulation.

Detailed Description
-----------------
Using a denture base material as a standard value which is the rapid heat cured acrylic resin and compare it with a new material which is a conventional acrylic resin with addition of titanium dioxide nano particles in surface roughness and measuring it by a device called stylus profilometer this will be done on 20 patients this trial will take about 6 months.
