A novel approach of restoring endodontically treated tooth by using cad-cam milled peek post and core system: A case report

Abstract
The choice of appropriate definitive restoration of endodontically treated teeth should be guided by the amount of remaining hard tissues as well as functional and aesthetic considerations. Post and-core materials with biomechanical properties similar to the dentin could also be advantageous in reducing the risk of root fractures. The high performance polymer Poly-ether-ether-ketone (PEEK) is an example of one such type of material. This case report describes the restoration of endodontically treated mandibular premolar with the use of CAD-CAM milled post and core system followed by restoration with full coverage porcelain fused to metal crown.
