Özet

With advancing technology, progress is also being made in the medical sector, just as in industry. One of these advancements is the efforts aimed at ensuring the development of students studying medicine. Among these efforts, one of the most prominent is those conducted in the field of surgery. Studies in this direction gain particular importance, especially in various bone surgeries. Screw fixation on vertebrae is applied in various bone operations such as fracture treatment of spinal bones and scoliosis treatment. This treatment is of critical importance both for patients and physicians because the success of this treatment depends on the success of screw fixation. In screw fixation, the screw is typically inserted through the pedicle region of the vertebra, traversing a delicate structure. If the screw protrudes beyond the pedicle region, it can lead to either fracturing of the vertebral body (middle column) or, worse, spinal cord injury. In this study, various models have been produced from hydroxyapatite-reinforced UV-cured photopolymer resins using vat polymerization, which is one of the 3D printing methods, to produce trial models to increase this success and present them to physicians. The sample productions were carried out by selecting three different cellular fill densities (gyroid) at a filling ratio of one, and screw pull-out tests have been conducted.
