    Background: Dental implants enhance masticatory efficiency in edentulous patients, yet discrepancies exist between objective assessments and patient perceptions. This study evaluated masticatory efficiency before and after implant rehabilitation using the two-color mixing test (Hue-Check Gum®) and Viewgum® software Version 1.4. 32-bit, correlating objective data with patient-reported outcomes. Methods: In a prospective study of 30 patients receiving implant-supported prostheses, masticatory efficiency was assessed objectively (VOH values via Viewgum®) and subjectively (10 cm VAS). Statistical analysis included Shapiro–Wilk, paired t-tests (VAS), and Wilcoxon tests (VOH). Correlation and regression analyses examined subjective–objective relationships. Results: Significant improvements occurred post-rehabilitation. VAS scores rose from 3.46 (95% CI: 2.54–4.39) to 7.29 (6.55–8.02; p < 0.001). VOH values decreased from 0.462 (0.426–0.497) to 0.438 (0.403–0.473; p = 0.001), confirming better chewing performance. No correlation was found between VAS and VOH, pre- (p > 0.346) or post-treatment (p > 0.980). Conclusion: Implant rehabilitation improves masticatory function objectively and subjectively. However, the lack of correlation underscores the need for dual assessment in clinical practice. Future studies should explore factors influencing satisfaction and performance to optimize outcomes.
