“…The stiffness mismatch between the intra-radicular post and the dental tissue also resulted in high stress concentrations along the post-dentine interface 27) . It has therefore been suggested that an ideal dental post would have high stiffness at the cervical region and that this stiffness should be gradually reduced to match the dentine stiffness at the apical end 43) . The compositional gradient of multilayer materials achieved in FGMs has been identified as a possible solution for this problem of mismatch of material properties.…”

This study aimed to compare the biomechanical behaviour of functionally graded structured posts (FGSPs) and homogenous-type posts in simulated models of a maxillary central incisor. Two models of FGSPs consisting of a multilayer xTi-yHA composite design, where zirconia and alumina was added as the first layer for models A and B respectively were compared to homogenous zirconia post (model C) and a titanium post (model D). The amount of Ti and HA in the FGSP models was varied in gradations. 3D-FEA was performed on all models and stress distributions were investigated along the dental post. In addition, interface stresses between the posts and their surrounding structures were investigated under vertical, oblique, and horizontal loadings. Strain distribution along the post-dentine interface was also investigated. The results showed that FGSPs models, A and B demonstrated better stress distribution than models C and D, indicating that dental posts with multilayered structure dissipate localized and interfacial stress and strain more efficiently than homogenous-type posts.

“…Particularly, poly(ether ether ketone) (PEEK) is the leading candidate of implant materials in the dental and orthopedic areas. [1][2][3][4][5] The chemical structure of PEEK is shown in Scheme 1. It can clearly be seen that the resonance stabilization along the entire macromolecule makes it unreactive and inherently resistant to chemicals and environment.…”

To improve blood compatibility of poly(ether ether ketone) (PEEK), surface modification with methacryloyl-functionalized phospholipid polymers was performed through self-initiation graft polymerization. The copolymers (PMA) of 2-methacryloyloxyethyl phosphorylcholine (MPC) and 2-aminoethyl methacrylate hydrochloride were synthesized by conventional free radical polymerization. The PMA was then immobilized with pentafluorophenyl methacrylate to obtain methacryloyl-functionalized MPC polymers (PMAMA). The degree of substitution of the methacryloyl group into the copolymer was nearly completed. The PMAMA was dissolved in 1-butanol and the solution was dropped on PEEK. UV light (350±50 nm) was subsequently irradiated on PEEK for various periods. Elemental analysis of the PEEK surface was performed by X-ray photoelectron spectroscopy and phosphorus and nitrogen signals due to the MPC units on PEEK were observed. The surface wettability of PEEK was also improved by immobilization of PMAMA. Plasma protein adsorption was effectively reduced on the PMAMA-immobilized surface regardless of the type of protein. Furthermore, PMAMA immobilization was also useful in reducing platelet adhesion on PEEK. In conclusion, methacryloyl-functionalized MPC polymers could be immobilized on PEEK by simple photo-irradiation, resulting in significant improvement in blood compatibility.
