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.
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.

Patients will receive titanium dioxide denture (made from acrylic resin with titanium dioxide nanoparticles) for 1 month in the initial phase then in the second phase after one month they will receive (rapid heat cured acrylic resin)denture according to the principle of crossover design
Patients will receive rapid heat denture for 1 month in the initial phase of the trial then in the later phase patients will receive titanium dioxide denture (made from conventional acrylic resin modified by titanium dioxide nanoparticles) according to the principle of crossover design
The Surface Roughness of the denture base will be measured and reported in micrometer unit
surface profilometry will be measured by stylus profilometer
Time frame: 6 months
