Background: The conventional restoration protocol for endodontically treated teeth with excessive coronal loss has been metal post and core followed by a complete crown. The present study was conducted to assess the clinical performance and patient satisfaction of PEEK crowns. Materials & Methods: 40 PEEK crowns in 40 patients of both genders were included. The crowns were examined for anatomic form, marginal integrity, surface roughness, restoration staining, marginal discoloration and color match at a time interval of 1 week, 1 month, 3 months, 6 months, one year. Patient satisfaction was also evaluated. Results: Out of 40 patients, males were 22 and females were 18. Anatomic forms at baseline, 3 months, 6 months and 1 year class I was 100%, 96%, 95% and 95% respectively and class IIwas 0, 4%, 5% and 5% respectively. Staining classI was 100%, 90%, 90% and 90% and class IIwas 0, 10%, 10% and 10% respectively.Periodontal status was class I seen in 100%, 86%, 80% and 65%, class II was 0, 14%, 14% and 30% and class III was 0, 0, 6% and 5%. Marginal discoloration class I was seen in 100%, 80%, 80% and 75% and class II was seen in 0, 20%, 20% and 25%. Colour match class I was seen in 100%, 100%, 100% and 90% and class II was seen in10% at 1 year. Surface roughness class I was seen in 100%, 95%, 95% and 95% and class II was seen in 0, 5%, 5% and 5%. Marginal adaptation class I was seen in 100%, 100%, 100% and 90% and class II was 10% at 1 year. The difference was significant (P< 0.05). Chewing efficiency was average in 10%, good in 50% and excellent in 40%. Coloir match was average in 5%, good in 30% and excellent in 65%. Comfort was average in 5%, good in 40% and excellent in 55%. Contour was average in 5%, good in 45% and excellent in 50%. The difference was significant (P< 0.05). Conclusion: The high level of accuracy of fit such as crown retention, marginal quality and marginal accuracy and aesthetic accomplished with PEEK material was deemed very satisfying.
