Summary

Patients need Endocrowns for their teeth usually use Emax as an etchable ceramic. Yet they have disadvantages that may influence the outcome of the endocrowns, among which is the high stiffness and rigidity owing to the higher modulus of elasticity (67.2 GPa)( compared to natural dentin (18.6 GPa) which may affect the marginal adaptation.so a less rigid material is needed. PEEKs (polyetheretherketones) are presented as alternative materials to metal and glass ceramics, Their elastic modulus comparable to those of cortical bone and dentin so the polymer could exhibit good stress distribution. Also they have high fracture resistance, and low abrasion to the antagonist enamel.

.but the investigators have to know clinically it is performance , so the investigators are going to have Parallel groups in a randomized clinical trial.
