Purpose: To evaluate the effect of bulb thickness on the weight of obturator prostheses and masticatory performance in edentulous hemimaxillectomy patients.Materials and Methods: A randomized, single-blind, three-period crossover trial was conducted with 17 edentulous patients. All patients were provided with three definitive 3D-printed obturator prostheses each. Obturators were divided into three groups: (1) group 1 (G1; 1-mm bulb); (2) group 2 (G2; 2-mm bulb); and (3) group 3 (G3; 3-mm bulb). After fabrication, the weight of each obturator was measured using a digital analytical balance. The patients used each obturator for a period of 2 weeks without a passive period (ie, they did not stop using the obturator). After using each obturator, masticatory function was evaluated with an adapted Sato questionnaire and the sieve test. Data were analyzed using one-way ANOVA and Pearson correlation analysis (α = .05).Results: According to the results of the Sato questionnaire and sieve test, G1 demonstrated the highest masticatory function scores (70.88 ± 9.39; 1.06 ± 0.06), while G3 exhibited the lowest scores (48.23 ± 7.69; 0.92 ± 0.05) (P < .001). The weight of the obturators was significantly different between groups (G1 = 31.58 ± 1.09 g; G2 = 33.99 ± 1.21 g; G3 = 36.57 ± 1.13 g) (P < .001). The correlation between masticatory function and the weight of the obturator was significant (P < .05).Conclusion: This study revealed that using 1-mm obturator bulb thickness was an effective fabrication method for improving masticatory function and reducing the weight of obturator prostheses in edentulous hemimaxillectomy patients.
