Patient Satisfaction and OHRQoL In Removable Versus Fixed Implant Prostheses

The wax of the trial denture was converted into heat-cured acrylic resin using conventional packing and flasking techniques. The prosthesis was finished, polished and screwed in the patient's mouth. Engaging (Internal hex) cylindrical, plastic patterns (Octa plastic cylinder, multi unit abutment, Red, Dentis, Daegu -Korea) were used to construct the primary copings of the telescopic prosthesis.The finished primary copings were scanned using a lab scanner (Shera Echo-scan 7. Dental Wings, Montreal-Canada). This was necessary to design and to mill the wax pattern of the secondary copings using CAD/CAM technology (Dental Wings Software, Dental Wings, Montreal -Canada). Secondary coping was designed to properly fit to the primary coping. The framework was then tried in. At that time it was ready for its intra-oral luting to the secondary copings.

Framework of the hybrid prosthesis is waxed using plastic copings attached to multiunit abutments. once the framework is finished , bite is recorded, teeth are set up and the waxed up prosthesis are tried in. IF accepted the wax is eliminated the wax up denture is converted inti heat cured acrylic resin
