Patient specific implant design and production for closure of skull defects

In order to provide a function on the body, implant as defined organic and inorganic substance that is placed in an appropriate place, means that the type of material to be placed with in the body in medicine. Taking into account the concept called as a prosthesis that completing artificially any part of the body that is lost and helping heal, for the purposes mentioned, artificial prosthesis structures such as joint prosthesis used in orthopedic surgery, placed in tissue, skull implant prosthesis that are used in brain surgery. The biggest advantages of implant prosthesis compared with other conservative treatment methods are much more robust, comfortable and reliable. In our country, due to traffic accidents and terrorist attacks, brain injuries and damages are frequently observed. Because of that sort of situation, in the process of treatment, brain trauma, skull implants are needed. All implants that are used for surgical purposes must be sterile. Depending on technological developments, according to the needs, there are various implant manufacturing machines, software programs and hardware. In this thesis, it is targeted investigations, and development of Cranial Implant Prosthesis used for closure of skull defects and implementation to the selected patients. For this purpose, as a method, the patient will be taken into specific image called as CT, that is, Computed Tomography. Using the program MIMICS and surgical simulation tools, 3D model of the skull is created and obtained cranial implant biocompatibility tests are applied and using Patran software program, finite element of titanium are analyzed. The maximum displacement of implant, maximum stress parameters are calculated with the statistical data and supported related pictures, photos and analysis. In our study, the implementation of skull implant which is made of titanium alloy by being done various analyses on a patient sample and the results are evaluated. Key words: Skull implant, Craniofacial implant, Rapid prototyping methods
