ODONTOMETRIC VARIABLES OF PONTIC ELEMENTS OF FIXED METAL CERAMIC DENTAL BRIDGES
Abstract
Purpose: The aim of this paper is to analyze the odontometric values of elements by lateral metal ceramic dental bridges. Material & Methods: For this goal there were observed and measured 455 elements from 151 patients. The measurement was made with an instrument for precise measure (schubler), with precision of 0.1 mm. The control group was compound from homolog natural teeth. Results: The per cent of males with fixed metal ceramic prosthetic appliances is 62.25%, and the per cent of females with fixed metal ceramic prosthetic appliances is 37.75%. The per cent of crowns and pontic elements by males with fixed metal ceramic prosthetic appliances is 61.48%, and the percent of crowns and pontic elements by females is 38.52%. Conclusions: The frequency of fixed metal ceramic prosthetic appliances and the frequency of pontic element and crowns in dental bridges of lateral sector evidently is higher by males than females. The total number of elements of lateral dental bridges by both jaws and both sexes gained as a result of our study shows statically suitable reports as a substitute for any two worked elements as abutment crowns in average are two. The occlusion cervical dimension of pontic elements in our study is higher that natural teeth for 23.49%. This situation affects evidently to increase strength and sustainability of the bridge and at the same time the masticator pressure will be distributed in the appropriate manner. In vestibule oral dimension the pontic elements of our study are for 8.82% narrower than natural teeth. Value that influence in protection of dental bridge from deformation and breaking. In mesio distal dimension the mean value of length of pontic elements in our study is for 16.13% lower than natural teeth. This situation will significantly influenced the strength of the bridge and will increase its masticator efficiency. Taking onto consideration these odontometric parameters in the construction of the pontic of fixed metal ceramic lateral dental bridge, there will be prolonged the longevity of prosthetic appliances, will be increased their preventive effect, and positively will influence on patients' oral hygiene. Based to the value of T-test, and according to the value of coefficient of probability (p<0.05), we can say that by our results the statistically significance is important and not by chance.
