SUMMARY:

Provisional removable partial dentures (PRPDs) are commonly used as temporary treatments in the oral rehabilitation of partially edentulous patients and are 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 assess
the clinical performance and patient-centered outcomes of oral rehabilitation with
PRPDs fabricated using conventional workflow (CP) and digital 3D printing workflow
(DP). This is a randomized controlled crossover clinical trial in which partially
edentulous patients were 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 was measured. The technical quality of the
PRPDs was evaluated using an adapted questionnaire; oral health-related quality of life
was assessed with the Brazilian version of the OHIP-14; patient satisfaction and
willingness to pay were measured using a validated questionnaire; and masticatory
performance was assessed with the mixing ability test. At the end of the treatment,
participants indicated their final preference for the type of denture. Descriptive analyses
and paired t-test and Wilcoxon tests were used, with a significance level of 5% and a
statistical power of 80%. The sample consisted of 11 participants, with a mean age of
43.27±14.40 years. It was observed that the 3D-printed PRPDs required less clinical and
laboratory time (p<0.05). Lack of stability was the most frequent issue among both
types of prostheses, being more prevalent in conventional PRPDs (72.73%). No
statistically significant differences were found between the groups in terms of oral
health-related quality of life, patient satisfaction, willingness to pay, or masticatory
performance (p>0.05). However, the majority of participants (63.64%) preferred the
conventional PRPD. The 3D-printed PRPDs require less clinical and laboratory time
and are comparable to conventional ones regarding oral health-related quality of life,
patient satisfaction, willingness to pay, and masticatory performance.
