Günümüzde, travmalar, kemik tümörleri veya osteonekroz gibi çeşitli nedenler ve artan yaşlı nüfusa da bağlı olarak kemik kayıplarına sıkça rastlanılmaktadır. Kemik kayıplarının giderilmesi ile hastanın kemik fonksiyonlarını devam ettirmesi, estetik görünümün korunması gibi hasta yaşam kalitesi korunmaya çalışılmaktadır. Gelişen teknolojiyle birlikte, kemik kayıplarının yerini alması için gözenekli yapıya sahip protezlerin tasarlanması ve üretilmesi oldukça yaygındır. Protezler, hasta için kullanıma sunulmadan önce birçok sayısal ve deneysel analizlere tabi tutularak biyomekanik olarak uygunluğu araştırılmaktadır. Bu çalışmada kiriş tabanlı kafes yapılardan bir mimari belirlenerek bu geometriye sahip farklı gözeneklilik oranlarındaki iskelelerin kemik rejenerasyonu için uygunluğunun araştırılması amaçlanmıştır. Bu doğrultuda, iskele modellerinin kemik benzeri davranışlarını belirlemek için akış analizleri sayısal olarak gerçekleştirilmiştir. Hesaplamalı Akışkanlar Dinamiği yöntemi ile yapılan akış analizleri sonucunda geçirgenlik değerleri hesaplanmış olup, yapı içerisinden geçen akış çizgileri ve yüzeylerde oluşan duvar kayma gerilmeleri kaydedilmiştir. Tasarlanan modellerin geçirgenlik performanslarına bakıldığında, tüm modeller trabeküler kemik geçirgenliğinin alt sınırının üstünde olduğu görülmektedir. Ayrıca, duvar kayma gerilmesi bakımından %50 ve %60 gözeneklilikteki iskelelerde kemik hücre gelişimi için olumsuz olabilecek gerilme değerleri meydana geldiği görülmektedir.

Today, bone loss is frequently encountered due to various reasons such as traumas, bone tumors or osteonecrosis, and the increasing elderly population. With the elimination of bone loss, the patient's quality of life is tried to be preserved, such as maintaining the bone functions of the patient and preserving the aesthetic appearance. With the developing technology, it is quite common to design and manufacture prostheses with a porous structure to replace bone losses. The biomechanical suitability of the prosthesis is investigated by subjecting it to many numerical and experimental analyzes before being put into use for the patient. In this study, it was aimed to investigate the suitability of scaffolds with different porosity ratios with this geometry for bone regeneration by determining an architecture from beam-based truss structures. Accordingly, flow analyzes were carried out numerically to determine the bone-like behavior of the scaffold models. The permeability values were calculated as a result of the flow analyzes made with the Computational Fluid Dynamics method, the flow lines passing through the structure and the wall shear stresses on the surfaces were recorded. All models considered for their permeability performance are above the lower limit of trabecular bone permeability. In terms of wall shear stress, it was observed that stress values that could be negative for bone cell development occurred in scaffolds with 50% and 60% porosity.
