Metal-reinforced polymethyl-methacrylate (PMMA) is considered the gold standard material for immediate loading on dental implants. However, mechanical problems under cycles can occur, such as fractures. To overcome these drawbacks, a novel polymer-based has been proposed. The aim of present in vitro comparative research to validate composite polymer developed replace metal-reinforced PMMA interim restoration due its advantages good proprieties, easier manufacturing, and handling. Ten restorations were CAD/CAM designed fabricated (five "ONLY" group, five group). All samples screwed into prototype models, simulating complete edentulous mandible rehabilitated with six straight Outcome measures breakpoint (load, N) displacement (mm) thought static, compression test behavior dynamic cyclic method (fatigue test). A total twenty tested. used each (10 static 10 dynamic), group (test control). specimens completed tests, planned. There was no statistically significant difference between groups all, breakpoint, fatigue tests. Breakpoint 1953.19 ± 543.73 N, while, it 2031.10 716.68 N control (P=0.775). 1.89 0.34 mm 1.98 0.75 again, (P=0.763). Under method, mean load 2504.6 972.15 3382 578.5 N. 877.4 579.3 (p value=0.121).
