23 Jul Implant and method for manufacturing mandibular implant with PEKK (polyetherketoneketone) supporting and fixing units and tissue engineering growth unit
Abstract
The invention provides an implant and a method for manufacturing a mandibular implant with PEKK (polyetherketoneketone) supporting and fixing units and a tissue engineering growth unit. The method includes steps: 1) image acquisition and three-dimensional model establishment; 2) molding unit and fixing unit design; 3) supporting unit design; 4) growth unit design; 5) individual composite-structure implant assembly; 6) individual composite-structure implant manufacturing; 7) in-vitro culture. A molding unit, fixing units, supporting units and the growth unit jointly form an individual composite-structure implant, the supporting units, the fixing units and the molding unit are made of PEKK materials and capable of providing sufficient mechanical strength to keep structural integrity from occlusion functional reconstruction, and the growth unit which is an internally degradable stent is capable of guiding new bone generation.
