Abstract
Introduction: Prosthodontic rehabilitation of teeth using crowns has seen several advances over the past couple of decades. Nevertheless, clinicians are still receiving crowns from a laboratory that may require varying degrees of correction or remaking. This study evaluated the clinicians' considerations in determining the prevalence of the need for rectification or remaking of crowns and the factors that influence them. Materials and Methods: The instrument for the study was a modified version of a previously adopted questionnaire. Through the questionnaire, each clinician collected demographic data and specific information about the level of acceptance or rejection. A Chi-square test was performed to explore the difference between the study characteristics and crown assessment categories. Post comparisons were performed with a z-test adjusted by the Bonferroni correction. Results: Proximal contact deficiency (35%) constituted the main reason for laboratory rectification of crowns, followed by shade mismatch (27%). Zirconia crowns were seen to have more clinical acceptance (70%) at the time of fit-in, while PFM crowns, by and large, either required adjustments or remake (86.2%). Specialists were more inclined to accept crowns or adjust them clinically (70.1%). Clinicians with more than ten years of experience were less likely to order a crown's remaking (5.7%). Conclusion: Rectification or remaking of crowns in the laboratory was found to be of sizeable quantity. The requirement for further adjustment of crowns in the laboratory was primarily due to proximal contact deficiency. The remaking of crowns was mostly mandated owing to the poor fit of crowns. Specialists and clinicians with more experience were less likely to have crowns remade and managed with chairside adjustments or in the laboratory.Copyright (C) 2013 - All Rights Reserved - Pharmacophore
