With the advancement of medical technology, whether or not orthopedics or dental equipment, there is a clinical need for customized services, using the integration mechanism of the rapid trial platform, combined with medical 3D images for the Patient Specific Implant (PSI) custom process.

However, according to the above practices, all kinds of products for implantation need to be commissioned by the factory outside the factory. Not only must the factory be in compliance with GMP regulations, but also the product license must be obtained for the manufacture of customized products. The procedure is too long and difficult to meet medical treatment. The need for emergency treatment.

In terms of cranioplasty technology, the appropriateness of the cranial face is related to personal self-confidence and image. Therefore, customized cranioplasty is the practice pursued by general orthopedics or dentists. Nearly 70% of domestic orthopedic or dental implant products are available. Relying on imports, however, the specifications and dimensions of imported products do not meet the needs of the Chinese people. Physicians often need to perform the size cutting, smoothing and filling, but still can not get the replacement size that fully meets the specifications; in addition, even the domestic production of orthopedics or dental implants Into the product, because of the need for cranioplasty, it is necessary to customize the specifications to meet the patient's specifications, but the restrictions require that the hospital need to cooperate with the manufacturer to provide the customized implant products and licenses required by the patient. Surgical replacement and this product belongs to the CLASS II or CLASSIII level. It takes at least 9 months to get a legal license. Such a lengthy certification procedure does not meet the urgent treatment requirements of the doctor. Some patients may even suffer from cancer that needs immediate treatment.
