SUMMARY:

Provisional removable partial dentures (PRPDs) are commonly used as temporary treatments in the oral rehabilitation of partially edentulous patients, being considered a low-cost and quick-fabrication alternative. Despite the advantages of digital technology in the fabrication of dental prostheses, there is a gap in the literature regarding studies evaluating digitally manufactured PRPDs. Therefore, the present study aimed to evaluate the clinical performance and patient-centered outcomes of oral rehabilitation using PRPDs fabricated through conventional (CP) and 3D printing digital workflows (DP). This randomized controlled crossover clinical trial included partially edentulous patients randomized into two groups according to the treatment sequence: CP-DP (initially rehabilitated with a conventionally fabricated PRPD and, after 3 months, with a 3D-printed PRPD) and DP-CP (opposite sequence). The time required for clinical and laboratory steps, as well as the number of clinical appointments, was recorded. Technical quality was assessed using an adapted questionnaire; oral health-related quality of life was evaluated using the Brazilian version of the OHIP-14; patient satisfaction and willingness to pay were measured through a validated questionnaire; and masticatory performance was assessed using the mixing ability test. At the end of treatment, participants indicated their final preference for the type of denture. Descriptive analysis and paired t-test and Wilcoxon test were used, with a significance level of 5% and a statistical power of 80%. The sample consisted of 18 participants rehabilitated with 21 PRPDs from both workflows, with a mean age of 46.78 ± 12.76 years. The 3D-printed PRPDs required less clinical and laboratory time and fewer clinical appointments (p<0.05). No significant differences were observed between groups regarding technical quality, oral health-related quality of life, patient satisfaction, willingness to pay, or masticatory performance (p>0.05). However, conventional PRPDs were more frequently selected as the final choice (71.43%). Therefore, 3D-printed PRPDs required less fabrication time and fewer clinical appointments, with clinical performance and patient-centered outcomes comparable to conventional ones. Nevertheless, conventional PRPDs were more frequently preferred as the final choice.
