| titleOfInvention | Preparation method of ultrahigh molecular weight polyethylene and/or hydroxyapatite 3D printing wire and dental implant |
| abstract | The invention discloses a preparation method of an ultrahigh molecular weight polyethylene/hydroxyapatite composite material 3D printing wire rod and a dental implant. The method comprises the following steps of firstly, mixing the raw materials in a mass ratio of 5-30%: mixing 70-95% of nano-grade hydroxyapatite powder and medical implant-grade ultrahigh molecular weight polyethylene powder, carrying out densification granulation, carrying out melt extrusion and wire drawing to obtain a 1.75 mm standard ultrahigh molecular weight polyethylene/hydroxyapatite wire material for 3D printing, setting 3D printing parameters, controlling the temperature of a printing spray head to be 200-230 ℃, the temperature of a printing bottom plate to be 20-50 ℃, the printing speed to be 20-40mm/s and the rotating speed of a cooling fan to be 2000-2500rpm, and starting printing after the nano-grade hydroxyapatite powder and the medical implant-grade ultrahigh molecular weight polyethylene powder are introduced into a three-dimensional dental implant model to obtain the ultrahigh molecular weight polyethylene/hydroxyapatite composite dental implant. The invention adopts 3D printing technology, the abutment part and the dental implant body are integrally formed, and the composite material dental implant prepared by using nano-grade hydroxyapatite powder and medical implant grade ultra-high molecular weight polyethylene plastic powder as raw materials has high strength, high hardness and impact strength, and has good biocompatibility and osteoinduction. |
