Abstract
STATEMENT OF PROBLEM: Several manufacturers have developed a digital workflow for removable prosthodontics. The Baltic Denture System is a 2-visit procedure for the digital production of complete dentures, but clinical studies comparing the system with conventional methods are lacking. PURPOSE: The purpose of this randomized, controlled, blinded crossover trial was to evaluate the impact of the digital versus conventional production of complete dentures on oral health-related quality of life (OHRQoL) measures. MATERIAL AND METHODS:Sixteen participants received 2 sets of new complete dentures produced with a digital (2 visits) and conventional (5 visits) workflow. Each complete denture was in clinical service for an observation period of 3 months. The order of the dentures was randomized, starting with digital or conventional followed by changing the set of dentures after 3 months. The primary outcome was the time-dependent change in the OHRQoL, assessed by using the Oral Health Impact Profile, German version (OHIP-G49), comparing the digital with the conventional workflow. The secondary outcome was the time needed for the fabrication process. The median values of OHIP-G49 total sum scores and OHIP-G49 dimensions were calculated for baseline and 14 days and 3 months after insertion of the dentures. Changes of sum scores over time and differences between the workflows were analyzed by using the Wilcoxon signed-rank test (α=.05). RESULTS: The data of 16 participants (11 men and 5 women; 66 ±8.5 years) were evaluated. The median values of the total OHIP-G49 sum scores and the sum scores of OHIP-G49 dimensions did not differ between workflows (P>.05). With digital dentures, more physical pain was observed after 2 weeks (P=.039). Participants with conventional dentures had less functional limitation after 14 days and felt less handicapped after 3 months (P=.036). Digital dentures were fabricated within 4 hours, whereas fabrication of conventional dentures took 10.5 hours for dentists and dental laboratory technicians. CONCLUSIONS: From the perspective of the participants, the fabrication method of the complete dentures had no significant influence on OHRQoL. However, digital dentures needed only 2 visits, 1 hour less chair time, and 5 hours less time for the dental laboratory technicians.
