2nd, according to Cranial defect model, design the global design structure of perfect matching.This prosthese is divided into load receiving part and interface
Layer.Boundary layer requires there is perfect matching.The heavy burden ability of load receiving part will meet the stress at Cranial defect position.Complete design
Prosthese passes through solidworks Software match function, section function, more intuitively observes prosthese and surrounding bone from cross section
Match condition, and pinpoint the problems in time and process；
3rd, design interface layer: prosthetic surface 3-5mm being contacted with surrounding bone, is designed trabecular bone structure, stimulates or induction week
Enclose Bone Ingrowth to prosthetic surface, realize the biological reconstruction of prosthese and surrounding bone, reduce prosthetic loosening rate, when extending prosthese use
Between；
4th, design load receiving part: according to the stress being calculated, design the solid construction meeting this heavy burden degree；
5th, load receiving part and boundary layer are by the printing integrated manufacture of 3d；Or boundary layer prints manufacture by 3d and load receiving part is casting
Make, then boundary layer is enclosed within after load receiving part and is fixedly connected.
Preferably, described load receiving part is connected by selective laser sintering with boundary layer.
Preferably, described load receiving part is connected by laser melting coating with boundary layer.
Further, described interfacial layer thickness is 3-5mm.
