Abstract

Background and aim: The crown and bridge work involves clinical and laboratory stages. The dental technician should provide the dentists with high-quality work. The aim of this study was to assess the quality of working casts for crown and bridgework provided to undergraduate dental students.

Methods: Sixty eight working casts used to make crown and bridge work for undergraduate dental students were assessed for a number of factors related to quality, in Fixed Prosthodontics Department at Damascus University. 

Results: The teeth were complete in 76.5% of the cases. The dies were free of bubbles in 73.5% of the cases, had die spacer in  2,9%, not stable in 17.6%, properly trimmed in 41.2% of them. The articulator was used in 61.8% of the cases.

Conclusion: Quality of working casts for crown and bridgework provided to undergraduate students is a cause for concern if the sample of cases seen in this study is typical. So, more attention should be paid to laboratory aspect during the undergraduate study in dental faculties.
