To evaluate the mastication function of the patient whose maxilla was reconstructed with individual titanium mesh and Chinese flap or combined with fibular flap. The superiority of this method on maxillary functional reconstruction was testified. Since March of 2001, 10 cases of maxillary defect were reconstructed with individual titanium mesh and Chinese flap or combined with fibular flap, and routine removal partial dentures were fixed after 3 - 6 months postoperatively. Assessment of occlusal force was proceeded by T-Scan II system (Tekscan company, USA). 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 < 0.05). The recovery rate of total occlusal force was between 27.05%-74.06%, and the average was 50.15%. This new three-dimensional maxillary functional reconstruction method had a satisfactory recovery in both of contour and function recently, especially restored the mastication function effectively.
