Objective To evaluate the mastication function of the patientwhose maxilla was reconstructed with individual tita- nium mesh and Chinese flap or combinedwith fibularflap. The superiority of thismethod onmaxillary functional reconstructionwas testified.Methods Since March of 2001, 10 cases of maxillary defectwere reconstructed with individual titaniummesh and Chi- nese flap or combinedwith fibular flap, and routine removal partial dentureswere fixed after 3~6 months postoperatively. Assess- ment of occlusal force was proceeded byT-Scan II system (Tekscan company, USA).Results The occlusal force analysis results indicated the asymmetry index of bite force and asymmetry index of occlusal contact area differed significantly between preoperation and postopertion (P
