Diastema often occured in maxillary complete denture resin base in the clinic,although “ Lucitone 199” had been used with more tensile strength.Mechanical ex-periments have proved the high transverse tensile stress (σ_x~+) concentrating in anteri-or teeth region and their palatal surface of maxillary complete denture resin basewhile it was exposed to vertical loading in center occlusion.Setting strengtheningnet in resin base has achieved better results.For evaluating purpose,twenty kinds
