PATIENT SPECIFIC IMPLANT DESIGN AND PRODUCTION FOR CLOSURE OF SKULL DEFECTS

Abstract

In order to provide a function on the body, implant asdefined organic and inorganic substance that is placed in an appropriate place,means that the type of material to be placed within the body in medicine.Considering the concept called as a prosthesis that completing artificially anypart of the body that is lost and helping heal, for the purposes mentioned,artificial prosthesis structures such as joint prosthesis used in orthopedicsurgery, placed in tissue, skull implant prosthesis that are used in brainsurgery. The biggest advantages of implant prosthesis compared with otherconservative treatment methods are much more robust, comfortable, and reliable.In many countries, due to traffic accidents and terror attacks, brain injuriesand damages are frequently observed. Because of that sort of situation, in theprocess of treatment, such as brain trauma, skull implants are needed. Allimplants that are used for surgical purposes must also be sterile. Depending ontechnological developments, according to the needs, there are various implantmanufacturing machines, software programs and hardware. In this study, it isintended to design and develop Cranial Implant Prosthesis to be used forclosure of skull defects and implementation to the selected patients. For thispurpose, CT images of patients are used. MIMICS software and surgicalsimulation tools are utilized for producing 3D model of the skull. Finiteelement analysis of titanium has been done by Patran software. The maximumdisplacement of the implant, maximum stress parameters are measured with thestatistical data and supported with related figures. Various analyses have beendone during the implementation of skull implant and the results are evaluatedin details.
