CREATECH MEDICAL

Createch Medical designs and manufactures metallic frames for dental prostheses that are personalized to meet each patient’s case requirements. Starting from a model of the actual implants provided by the doctor, Createch manufactures the frame attached to the implants and the supporting base for the teeth. The frame and teeth supporting base are mainly manufactured on single piece Ti6Al4V or CrCo by micromilling. During the design and manufacture of the prosthesis, exceptional care must be taken on the frame-implant connections. A slight deviation on the position of one of those connections would generate stresses on the jaw of the patient and, thus, pain; making the prosthesis unacceptable. Moreover, the stresses induced by the clamping of the prosthesis could even generate the rejection of the implants. Defined test-cases Concerning the case of Createch Medical, three test-cases have been defined for their analysis within the project. They are related to the present manufacturing chain from Createch-Medical, covering the characterization of the model with the dental implant analogues and the precision milling process of the dental frames. Related to these test-cases, different working groups have been assembled in order to define and develop solutions for the different problems defined by the industrial end-user. Next, the different test-cases and the tasks related to their solution are exposed briefly. Figure aside shows a poster summarizing visually the technical work carried out during the project related to the test-cases from Createch-Medical.
