Bone model, bone filler and process for producing bone filler

Abstract

The invention provides a process for producing a bone filler, in which a bone filler for filling a cavity of bone defect can be produced with high precision. The process for producing a bone filler fundamentally includes the bone model fabrication step (step 1) of fabricating a bone model; the image forming agent filling step (step 2) of filling an image forming agent into a cavity of bone defect of the bone model obtained in the bone model fabrication step; and the bone filler production step (step 3) of producing a bone filler for filling the cavity of bone defect on the basis of the image forming agent having filled the cavity of bone defect of the bone model in the image forming agent filling step.

Description

technical field [0001] The invention relates to a bone model, a customized bone filling material and a manufacturing method of the customized bone filling material. More specifically, the present invention relates to a bone model in which the ups and downs, asymmetry, etc. of the model can be seen at a glance through contour lines, grid patterns (position maps) and the like thereon. The present invention also relates to a method for manufacturing a bone filling material. This method refers to digitizing the shape of the patient's bone through CT or MRI, and then manufacturing a bone model based on the digitized information. Next, the surgeon fills the bone with the modeling material. In this model, a bone filling material shape is formed, and the formed bone filling material shape is digitized again, and the bone filling material is manufactured based on the digital information. Using this method, high-precision bone fillers can be manufactured. Background technique [000...

Problems solved by technology

But when non-self substances like silicon are implanted, not only are a lot of immunosuppressants needed, but also, since the implanted substances are always non-self to the body, regular checks are required

Inflammation can also be triggered by the body not adapting to substances such as silicon implanted

[0015] Normally, bone fillers are weak, so when impacts or strong forces from the outside are applied to them, the bone fillers are damaged

In addition, since the bone filling material is not the patient's bone, even if the bone filling material is implanted in the bone defect, the bone filling material may fall off when an external force is applied to it.

[0016] Although patients with osteodystrophy and other diseases can confirm the bone deformation by visual inspection, it is difficult to obtain objective information on the degree of bone deformation
