Interventions

Type	Name	Description
DEVICE	CAD/CAM monolithic denture	Based on the workflow suggested by the Ivoclar digital denture, conventional complete dentures will be scanned by using desktop scanner (Medit T710). The cameo and intaglio surfaces of the complete dentures will be scanned, and the scanned data will be exported as Standard Tessellation Language (STL) file to start the milling process. For the milling process, monolithic denture will be milled from a bicolored disk (Ivotion). One side is the denture base material made of high impact optimized polymethyl methacrylate (PMMA) while the other is the teeth material made of highly cross-linked PMMA with no filler. The bicolor disk is milled in a 5-axis milling machine in wet condition, through an uninterrupted milling process. Following the fast milling process the dentures will be finished and polished.
DEVICE	Conventional denture	The conventional set will be fabricated with the 5-appointment process: preliminary impressions (first appointment); definitive impressions (second appointment); interocclusal records and tooth selection (third appointment), the size of the teeth will be selected according to the library provided by 3Shape Dental System software to match the disc size; wax trial placement (fourth appointment); and denture adjustment and placement (fifth appointment). Conventional CD will be fabricated with the conventional lost wax technique and heat-polymerizing acrylic resin. The heat-polymerized CDs will be finished, and polished before placement. Adjustments will be made for the polished surface, tissue surface, borders, and occlusion. Occlusal errors will be adjusted through clinical remount of the finished dentures.
