Objective: To compare the dimensions of full coverage restorations that are recommended in literature with those being delivered by the laboratories at multiple tertiary care dental institutes.
Study Design: Descriptive cross sectional study.
Place and duration of study: Three tertiary care institute laboratories in Rawalpindi/Islamabad region, from October to December 2015.
Material and Methods: The thickness of functional and non-functional cusps for both complete cast and metal ceramic crowns fabricated in the dental laboratories of multiple teaching hospitals were measured using Iwanson gauge. Data was recorded in specially made pro forma and analyzed using SPSS 20.0.
Results: The thickness of functional cusps of both cast metal and metal ceramic crown were of less than ideal thickness where as non functional cusp of cast metal crown was bulbous.
Conclusion: There is a significant variance in the dimension of metal and metal ceramic crowns fabricated in the laboratories than the dimensions recommended in literature.
