About this trial
This is a two-armed, single-center clinical study evaluating performance, efficacy and safety of three dimensional (3D) printed complete dentures and milled complete dentures during a 5-year follow-up period. The primary objective of this clinical investigation is to evaluate survival rate, i.e. subjects with survived dentures in both upper and lower jaw, of 3D printed complete dentures and milled complete dentures after 1 year (in each of the groups separately).

Denture success
A denture will be considered successful if all the following criteria are fulfilled: Absence of major technical complications. Absence of major biological complications. Functional occlusion and mastication, assessed by clinical examination and OHIP-EDENT. * Assessed by OHIP-EDENT - Q1 from OHIP: "Have you had difficulty chewing any foods because of problems with your teeth, mouth or dentures?", where score 0-2 would be considered successful (0=never, 1=hardly ever, 2 = occasionally). Absence of patient reported discomfort, assessed by OHIP-EDENT. * Assessed by all questions in Physical pain section of OHIP-EDENT - Q4 "Have you had painful aching in your mouth?", Q5 "Have you found it uncomfortable to eat any foods because of problems with your teeth, mouth or dentures?", Q6 "Have you had sore spots in your mouth?, Q7 "Have you had uncomfortable dentures?", where score 0-1 would be considered successful (0=never and 1=hardly ever).
Denture adaptation accuracy
Evaluation of accuracy of 3D printing and milling technology will be made using Geomagic Software at time of final denture insertion. The denture intaglio at insertion will be compared with the final impression as reference scan.
Denture retention force
Retention force of the dentures will be evaluated by applying a dynamometer gauge at the following locations: Post dam, Tuberosities and retromolar pads.
