Abstract:

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<0.05). The recovery rate of total occlusal force was between 27.05%~74.06%, and the average was 50·15%.Conclusion　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.
