Özet

In recent years, computed tomography (CT) imaging techniques have played a significant role in designing personalized prostheses which are dental devices used in cases of mandible loss or deformation. These techniques provide data to analyze the patient's mandible structure in detail and design a customized mandible prosthesis based on that information. CT images are used to  create a three-dimensional model of the patient's mandible structure. This model visualizes the shape, dimensions, and other anatomical details of the mandible bones. In this study, the processing and analysis of these images are done using Materialise Mimics and a computer-aided design (CAD) software Materialise 3-Matic. The designed prosthesis manufactured using a selective laser melting (SLM) device with 20 μm layer thickness using Titanium – 6 Aluminum – 4 Vanadium (Ti-6Al-4V) material which is proven to be biocompatible in the literature and medical applications. The size range of Ti-6Al-4V grade 23 powders used in our study is 15-53 μm and they have a spherical morphology. Personalized mandibular prosthesis, which was specially designed for the persons specific bone structure was produced using thismethod. To reduce the surface roughness, the produced prothesis was polished as a post-process.
