Use of Customized Polyetheretherketone (PEEK) Implants in the Reconstruction of Complex Maxillofacial Defects

Maxillofacial Reconstruction Using Polyetheretherketone Patient-Specific Implants by “Mirroring” Computational Planning

“…Although several materials such as autografts, allografts, xenograft, and metallic or nonmetallic material alloplastic bone substitutes have been reported for use in reconstruction of such deformities with varying degrees of success in the past 20 years, the ideal solution has not been discovered to date [1][2][3][4][5][6][7][8][9].…”

“…The recent introduction of individually preformed alloplastic implants allows anatomic 3D shaping, as opposed to conventional implants, which require major intraoperative manipulations [2,5,7,8].…”

Clinical application of triangular parabolic PEEK mesh with hole button produced by combining CAD, FEM and 3DP into cranioplasty

“…Another important factor to consider as implantation material is its biomechanical properties. PEEK has elastic modulus which is close to the one of the cortical bone (peek, E=3~4 GPa; cortical bone, E=4~18 MPa; titanium, E ≈ 110 GPa), which means, PEEK compared with titanium is easier for bone integration rather than bone loss, thus reducing the failure rate of implant [15,16,22]. Although the molecular chain structure of PEEK exhibits relative rigidity, it is quite flexible and can be reconciled with large deformed plastic flow under uniaxial tension and compression.…”

The Changing Concepts in the Retention of Maxillofacial Prosthesis From Past to Present- A Review

“…32 PEEK (Polyetherether Ketone) is a polymer which has become recently familiar due to their biocompatibility, strength, stiffness and durability. 33 Owing to its mechanical and physical properties being similar to bone and dentin, PEEK can be used for a number of applications in dentistry. 34 PEEK exhibits excellent biocompatibility and stability when exposed to body fluids.…”

“…The patients showed excellent postoperative aesthetic and functional results without complications such as infections or extrusions. 33 …”
