TO ASSESS THE IMPRESSION ACCURACY IN CAPTURING THE UNPREPARED TOOTH SURFACE IN FPD PROCEDURES DONE BY GRADUATE STUDENTS

Abstract

Accurate impressions are a critical ingredient in our ability to deliver quality prosthesis to patients. An accurate well taken impression has many qualities, but the key factor is obtaining adequate margin flash.
To assess the impression accuracy in capturing unprepared tooth surfaces in fixed partial denture procedures done by graduate students.
The study was performed in the out patient department of Saveetha Dental College. Data required for the study was procured from the Dental Information Archiving Software. A search was done on the digital case sheets recorded between june 2019- february 2020 from the department of Prosthodontics. The search led to a 4200 plus information on fixed prosthesis impression. The data was sorted in excel and statistically analysed using the IBM SPSS software analysis and the results tabulated.

The unprepared surface of the tooth is recorded well in all impressions except in few with regard to mesial, lingual surfaces which are statistically significant and thicker light body impression was observed.
Graduate trainee students are able to record the impression of the unprepared surface of the tooth with great details except very few specific areas not being recorded and secondary outcomes such as putty exposure through light body impression required improvisation.
