Peek Framework with Denture

Peek RPD

PEEK frameworks combined with acrylic resin denture teeth and heat-cured acrylic resin denture bases as an alternative to conventional Co-Cr frameworks. PEEK presents favorable properties such as excellent biocompatility, good mechanical properties, good thermal and chemical resistance, white color and low specific weight that permit the fabrication of lighter metal-free RPDs eliminating the esthetically unacceptable display of metal claps and the risk for metallic taste and allergies of conventional RDP metal frameworks..CAD-CAM PEEK RDP frameworks can be fabricated by several methods such as direct milling of PEEK blanks or 3D printing of a resin/wax pattern framework which is then thermo-pressed using the conventional lost-wax/resin technique .Due to its high elasticity, PEEK could reduce stresses and distal torque on the abutment teeth during function.PEEK RPDs could be recommended for patients with poor periodontal conditions.
