ABSTRACT
Objectives: To evaluate teeth preparation designs for metal-ceramic crowns in private dental practice in Jordan. Materials and methods: One-hundred and seventy two dies were included. Different aspects of tooth preparations were quantified, analyzed and compared with the recommended guidelines.
Results: Almost 64% of preparations finish lines were positioned subgingivally. Shoulder finish lines were observed in 74.4% whereas 22.7% showed chamfer finish lines. Total occlusal convergence angles were 29.8° in BL plane, 24.7° in MD plane.
Conclusions: Dental practitioners in private practice in Jordan did not fully adhere to the recommended guidelines for tooth preparations for MCRs.
