Abstract :
The incorporation of computer-aided design/computer-aided manufacturing (CAD/CAM) technology into complete denture
fabrication brings about several advantages to the fabrication process, providing better predictability of the desired outcomes and
high accuracy of denture fit, mainly because the milling of prepolymerized acrylic resin eliminates the shrinkage of the acrylic
base. Also, there is a decrease in the porosity when compared to a conventionally processed denture, and consequently there is a
decrease in the retention of Candida albicans on the denture base.The presented workflow for complete denture fabrication presents
a totally wax-free manufacturing process, combining rapid prototyping (RP) and rapid milling. With the presented technique, the
maxillomandibular relation (MMR) and the ideal setup of the tooth arrangement are developed by using occlusion rims and trial
setup made with RP. For the definitive final denture, the denture base and the basal surfaces of the conventional denture teeth were
milled according to the individual clinical situation. Posteriorly, the teeth were adapted and bonded into the milled sockets of the
milled base.
