ABSTRACT

Long term success of fixed partial denture depends on a variety of factors, one of them being accuracy of fit between the restoration and prepared tooth structure. The marginal fit of a fixed partial denture to the supporting tooth structure can influence the strength of the restoration. Very few studies have been done to evaluate the marginal fit of fixed partial dentures during framework trial. Case records were collected from DIAS (Dental information archiving software). This university setting consisted of 413 patients. Data was tabulated with parameters of Name, Age, Sex, Satisfactory level of marginal fit of the framework. Data was imported into SPSS for statistical analysis. Descriptive statistics having frequency percentage and chi sq. test was done for association. 94.43% of the population's frameworks marginal fit was found to be satisfactory. The satisfactory results were found to be higher in males than females comparatively. The age group 31-40 yrs had satisfactory results compared to any other age groups. Within the limitation of the study, short term clinical data suggest that the marginal fit of the frameworks are satisfactory. Further extensive research can be done with a larger sample size.
