ESTIMATION OF REFERENT CEPHALOMETRIC PARAMETERS IN DENTAL PROSTHETICS

Estimation, of the inclination of the occlusal plane and its spatial o rientation during the insertion of plaster casts in the articulators s pace, and control during the clinical phase of the prosthetic work, is one of the hey problems in dental prosthetics. The aim of this invest igation was to compare the relations of the basic roentgencephalometri c parameters applied and to determine their reliability. Five angular variables were analysed: OP-MdP, OP-PP, OP-CP, OP-FP and OP-SNP, on a sample of 86 radiographs of subjects with almost normal occlusion. by applying basic statistical parameters and the correlation's analysis. The results gave mean values of the investigated variables with estima tion of their variability and level of mutual correlation, which can, be used when determining individual inclination of the occlusal plane. Parameters FP and SNP showed significant stability and reliability wh ich can be successfully applied in prosthodontics.
