The assessment includes quality of materials provided by Dentsply Sirona Lab by using printers for AM (M series, Carbon 3D 1089 Mills Way, Redwood City, CA 94063). This assessment will be done by clinical review of the AM dentures on fit and quality. In addition, the evaluation includes a patient survey to assess current dentures and the new AM dentures with a subjective comparison of both.\n\nThe target subjects are male or female, 18 years and older with the need of a full denture in one or both jaws, being completely edentulous. The newly fabricated denture is to replace an existing full denture. For this descriptive study, no minimum number of patients is defined, but to achieve a reasonable subject number, a minimum of five (5) and a maximum of ten (10) patients will be enrolled, i.e. ten to twenty (10-20) denture arches will be fabricated within this study.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'The investigational device is part of a treatment concept for edentulous patients of all ages, gender and races.
