Background Bite forces required to masticate different food consistencies remain unknown, complicating dietary guidelines following mandibular reconstruction. This study quantifies the forces required for solid foods and estimates safe bite limits postreconstruction. Methods Twenty food items were prepared according to IDDSI Levels 5 through 7b. Incisor and molar bite forces were measured using a custom‐built force meter. Finite element (FE) analysis simulated safe force thresholds for single‐, double‐, and triple‐segment mandibular reconstructions. Results Bite force increased with food consistency, ranging from 4.6 N (IDDSI 5, incisors) to 45.4 N (IDDSI 7b, molars). Molars required higher forces than incisors (mean difference 9.0 N, p < 0.001). FE analysis indicated safe bite forces of30–115 N depending on reconstruction complexity and bone union. IDDSI 5 foods were safe in all cases, while higher levels often exceeded thresholds. Conclusion These findings support evidence‐based dietary recommendations after mandibular reconstruction using the IDDSI framework. |
