Abstract :
Aim: To compare the flexural strength of PEEK-Reinforced PMMA in provisional restorations produced through 3D printing and traditional fabrication methods.Materials and Methods: A total of 30 tooth-colored PMMA acrylic resin samples, each measuring 65 mm × 10 mm × 2.5 mm, were prepared. These samples were equally divided into three groups, with 10 specimens in each: Group I (Autopolymerized PMMA with 3 wt% PEEK), Group II (Heat Polymerized PMMA with 3 wt% PEEK), and Group III (3D Printed PMMA with 3 wt% PEEK). The flexural strength of the specimens was assessed using a three-point bending test on a universal testing machine. Statistical analysis was performed using one-way ANOVA, followed by intergroup comparisons with the POSTHOC Bonferroni test.Results: The highest mean flexural strength was observed in Group I (70.96 MPa), followed by Group II (55.27 MPa) and Group III (30.34 MPa). One-way ANOVA indicated a statistically significant difference (P < 0 n=5) n=5) n=5).> 0.05). At 24 hours, both the groups showed significantly lower (p < 0> 0.05).Conclusion: Muscle activity varied with different materials of the splint and duration of use. Both splints helped in the adaptation of muscles to new vertical dimensions of occlusion at 8 weeks with lesser variation between with and without splint position.
