PTJ meets or exceeds the quality standards of the world’s most demanding industries with our state of the art equipment and quality standards. Our precision and productivity is made possible by our ultimate success factor: the presence of skillful, knowledgeable PTJ experts in Orthopedic Implants 3d printing and more additive manufacturing parts.
As a new type of additive manufacturing technology, 3D printing has been successfully used on a large scale in the field of orthopedics and dentistry. A batch of 3D printed patient customized osteotomy guides, orthopedic implants, dental implants, etc. have been certified by the European Union (European conformity, CE) and the US Food and Drug Administration (Food and Drug Administration, FDA) approved for clinical use. In 2015, the National Food Quality Supervision and Inspection Center also approved China’s first 3D printed hip joint product, and it has begun to be used in large-scale clinical applications.
Based on its own digital advantages, 3D printing technology can effectively meet personalized and precise medical treatment and improve efficiency, and has been recognized by professionals and ordinary people. Medical devices prepared by 3D printing not only have the advantages of customization, manufacturability and mechanical properties, but also have a fast preparation process without additional storage and transportation costs; the use of 3D printing technology has short operation time, small trauma area, and success rate. High, the patient suffers less pain, recovers quickly, and has fewer sequelae.
Professional doctors use computerized tomography (CT), magnetic resonance imaging (MRI) and other imaging technologies to reverse or 3D reconstruction to simulate the three-dimensional image of the bones of the missing part, which is used for the 3D printed preoperative guide plate, which is then obtained by layered solid manufacturing technology The bone prototype assists traditional mechanical processing to manufacture bone substitute prostheses that can be implanted in the human body.
3D printing orthopedics commonly used electron beam melting, laser sintering 3D printing metal materials Ti6Al4V, cobalt-chromium alloy and stainless steel powder. Under the computer-aided design, 3D printing can quickly manufacture special-shaped personalized implants, and at the same time, it can manufacture micropores of controllable size. These microporous structures can reduce the elastic modulus of the metal material in the physical part of the implant and reduce the stress shielding; on the surface of the implant, it can promote the osseointegration between the metal and the bone. Bionic artificial bone made of PEEK material is also a good choice.
