The study aimed to compare the effects of fully digital versus conventional complete denture fabrication on oral food processing (mastication and swallowing of solids) in edentulous patients, using the Test of Mastication and Swallowing Solids (TOMASS). In a randomized crossover study design was carried out on 14 completely edentulous participants (age 50-65 years, both sexes) in good general and oral health, each participants received two sets of dentures: one fabricated with conventional workflow (physical impressions, tooth arrangement, processing into heat polymerized acrylic) and one fully digital workflow (Intra-oral scanning , CAD/CAM design, 3D printed base and teeth,). Each denture was worn for 3 months; with a 2 week "wash out" period between wearing periods, during which participants reverted to their old dentures or no dentures. The order (Conventional complete denture first vs Digital complete denture first) was randomized. At the end of each denture period, Oral food processing performance was measured using TOMASS (solid cracker test): Swallowing threshold and TOMASS test parameters that include number of bites, number of masticatory cycles, number of swallows, and total time (from first bite to last swallow)
