Abstract

The aim of this study was to evaluate the efficiency of using various auxiliary tools used in the stage of highlighting the cervical limit of dental preparations. We obtained a series of 20 dental preparations from 10 clinical cases, through the Medit program, then introduced into the ExoCAD program, assessing the quality of dental preparations and the quality of scans were and classifying them in the table in 5 possible ratings: very good, good, satisfactory, poor, very poor.

For each preparation, the cervical border was determined digitally using 5 methods provided by the ExoCAD software: Detect Supragingival, Detect Subgingival, Draw Non-magnetic, Draw Magnetic Supragingival, Draw Magnetic Subgingival. In our study, from the results obtained for all 20 preparations, the most advantageous functions for determining the cervical limit were “Detect Subgingival” and “Draw Non-magnetic”, both obtaining the lowest values for 35% of the preparations, but discrepancies can be observed between the values obtained for preparations of the same tooth type, but in different cases.

Automatic detection may seem innovative, spectacular and easy for a novice operator, but the difficult clinical situations, require the use of manual functions for the best possible detection of the preparation edges.
