Description

[0001] The present invention relates to a medical implant manufactured using a 3D printer,

The present invention relates to a method for treating an asymmetric region in a human body, in particular, a method for acquiring 3D information by scanning bones and preforming a 3D model of a one-to-one scale with the obtained information, The present invention relates to a medical implant that is manufactured using a 3D printer that is more accurate and aesthetically superior to a conventional implant.

Unlike westerners, Asians' face bones are more flatter and more angular (tucked clowns and square jaws), which makes them more likely to impress.

In Korea, vaginal liposuction or x-ray reduction has been developed.

However, these surgeries are not merely good, and can not be quantified as to how much fat transplantation will be absorbed and how much will be transplanted. In addition, the less experienced physician performed the jawbone surgery, too much to be cut to the extreme cases of damage to the nerve can be disadvantageous.

For example, in the case of a first-order side effect in which the left and right jaws are asymmetric due to a great reduction in the left jaw bone, the majority of the conventional molding therapy is to make the right jawbone sharply and symmetrically.

However, the above conventional molding treatment tends to cause a secondary molding side effect which causes a cross-sectional defect of a normal part and causes a larger side effect.

(3) an implant round shaping step of filling the formed part 300 in the defective part 110 of the 3D model 200 and shaping the outer surface of the formed part 300 into a desired shape to produce an implant circular part 400; And

(4) an implant manufacturing step of fabricating an implant (not shown) with a material harmless to the human body based on the implant circular shape 400;

The present invention provides a medical implant manufactured using a 3D printer.

According to the present invention, in order to treat an asymmetric part in the face, especially in a human body, the bone is scanned to acquire 3D information, and a 3D model of a one-to-one scale is preformed as a 3D printer by using the obtained information, The present invention provides a medical implant that is manufactured using a 3D printer that is more accurate and aesthetically superior to a conventional implant.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a process of fabricating a medical implant using the 3D printer of the present invention in order.

As shown in Figure 1,

In the medical implant manufactured using the 3D printer of the present invention,

(1) a scanning step of scanning a bone periphery 100 including a defective part 110 with a scanner to obtain 3D information;

(2) a 3D modeling step of transmitting the 3D information to a 3D printer to produce a full-size 3D model 200 of a bone surrounding region 100 including the defective region 110 using the 3D printer;

(3) an implant round shaping step of filling the formed part 300 in the defective part 110 of the 3D model 200 and shaping the outer surface of the formed part 300 into a desired shape to produce an implant circular part 400; And

(4) an implant manufacturing step of fabricating an implant (not shown) with a material harmless to the human body based on the implant circular shape 400;

And the like.

FIG. 2 is a photograph of the vicinity of a bone including a defect site in the present invention,

3 is a photograph of a 3D model taken in the present invention,

FIG. 4 is a photograph of an implant circle formed by filling a mold with a 3D model in the present invention.

As shown in the order of FIG. 2A, FIG. 3A, FIG. 4A, or FIG. 2B, FIG. 3B and FIG. 4B,

The medical implants manufactured using the 3D printer of the present invention are largely

(1) a scanning step, (2) a 3D modeling step, (3) an implant round shaping step, And (4) an implant manufacturing step.

Nowadays, due to the development of 3D printers, there is an attempt to make an implant directly with a 3D printer. However, these attempts have not been able to obtain the accurate 3D information of the defect site. Therefore, when the implant is inserted into the human body, the dimensions of the implant do not match exactly, so that it is often necessary to smooth the implant in the surgical field.

Therefore, the present invention produces a full-scale 3D model 200 of the bone periphery 100 including the defect site 110 and directly manufactures the implant circle 400 suitable for the defect, 400) has an advantage that it is possible to produce a product having an accurate dimension of the implant (not shown) and having no sense of foreign body to a person and having a good esthetic feeling.

The present invention uses the scanner CT scanner,

The molded product 300 is made of PVA (polyvinyl alcohol) clay,

The implant may be characterized by using silicon.

The PVA (polyvinyl alcohol) clay has an advantage that it can easily form a shape, and the silicon has an advantage that a doctor can freely perform carving at an operation site during an insertion operation.

FIG. 5 (A) is a photograph of a bone around a defect including a defect site in the present invention,

Fig. 5 (B) is a photograph simulating an implant circular shape filled with a molding in a 3D model according to the present invention.

As shown in Figure 5,

The present invention is characterized in that the bone periphery 100 includes a normal noncontact hand 110 'which is symmetrical to the left and right of the cutout 110,

In the above (3) implant round shaping step,

When the implant 300 is filled in the defected portion 110 and the outer surface of the molded product 300 is shaped into a desired shape to form the implant circle 400, .

6 (A) is a photograph of a 3D model taken in the present invention,

Fig. 6 (B) is a photograph of an implant circle formed by filling a molded article in a 3D model and molding the implant.

FIG. 6 shows a case where both the left and right sides are missing or depressed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.

It is therefore intended that the appended claims cover such modifications and variations as fall within the true scope of the invention.
