Ankle-foot-orthoses (AFOs) are externally applied assistive devices that are prescribed to the patients with neuromuscular dysfunctions in order to improve abnormal lower limb motor functions. AFOs are mainly used to control the range of motion of the ankle joint, to compensate for the muscle weakness caused by different motorneuron diseases, to im...
An ankle-foot orthosis (AFO) is an externally applied assistive device that encompasses the lower leg, ankle, and foot of the human body. In the current one-piece passive-dynamic AFO design, the trimming process is performed from lateral and medial parts of the ankle to ensure desired rotational displacement (hereafter referred to as Design I). In...

In this study, a biomechanical application of three dimensional (3D) printing method was implemented to produce a subject-specific insole. It was aimed to design and manufacture a customized total-contact insole operating a free mobile application that enables to create 3D scans of an object and a 3D printer device in this application. First, two d...
Ankle-foot orthoses (AFOs) are typically prescribed to improve the gait function of ambulatory children with neurological conditions such as cerebral palsy or spina bifida. Due to the excessive and repetitive loading conditions, plastic material deformation can be observed in AFOs, especially over the lateral and medial parts of the ankle, which li...
This work focuses on the development of a reconstruction process using 3D photogrammetry for metal objects, which are often difficult to scan in three-dimensional (3D) due to their shiny, smooth and featureless surfaces. Usually, expensive 3D scanning technologies are used for high accuracy reconstructions. This research presents a novel approach u...
There are approximately 35 to 40 million people worldwide who require assistive devices, including prosthetics and orthoses. Most amputee
patients have a lower amputation. The high cost of prosthetics, long production and delivery times, the frequent need for prosthetics in
growing children and limited accessibility to prosthetics are common compla...
Currently, additive manufacturing method and 3D printing technologies are used in almost every industry, profession, and field for a vast array of purposes, from the creation of basic models, toys, sophisticated art and fashion products to complex and functional parts for aviation industry. The scientific discipline of biomimetics draws inspiration...
Nasal dilators are medical devices used to relieve respiratory distress caused by structural anomalies in the nasal valve. These devices, which are applied to the nose externally or internally, widen the nasal valve part of the nose, reducing the air resistance and facilitating breathing. The structure of the nose varies from person to person, and...
Spinal instrumentation, which is based on the partition of the applied loads acting on the spine, is employed to keep the anatomic alignment of spinal segments from the upper body to the lower body portions. Stabilization and maintenance of curve alignment are the main goals of spinal instrumentation, especially in scoliosis. The success of the pos...
Today, the use of 3D scanning methods is increasing in a wide range of industries from biomedical to game production. The photogrammetry method is in demand by 3D scanning users due to its portability, photorealistic textured modeling, and low cost. Scanned objects vary according to industries and can have various materials, geometries and textures...
3B baskı teknolojilerinden biri olan ergiterek yığma ile modelleme (FDM) üretim teknolojisi ve polilaktik asit (PLA) malzemesi kullanarak farklı dolgu deseni ve yönüne sahip çekme testi numuneleri üretilmiş ve dolgu deseni ve yönünün çekme dayanımına olan etkileri incelenmiştir. Beş farklı dolgu deseni (eş merkezli, ızgara, üçgen, 3B altıgen, zik z...

Fotogrametri, çekilen fotoğraflar vasıtasıyla bir obje veya çevre ile ilgili ölçümler ve verilerin toplanarak yorumlanmasını ele alan bir bilim dalıdır. Bir başka ifadeyle fotogrametri, bir nesnenin veya ortamın konum, şekil ve büyüklük gibi geometrik özelliklerinin elde edildiği yöntemin adıdır. Bu yöntemle elde edilen veriler sayesinde fotoğrafla...
Orthopedic fixation devices have been employed in the treatment of spinal diseases. Special fixation devices have been developed to decrease the effect of spinal injuries and deformities and have been used to decrease the neurologic back pain of the patients. In this study, the finite element spine model of an adolescent idiopathic scoliotic patien...
In spine biomechanics, the spinal fusion method has been used to correct the abnormal curvature of the spine by surgical operations. The goal of this study was to generate a three-dimensional finite element model of two-level lumbar vertebrae. The anatomical three-dimensional model was developed from computed tomography data. To provide the stabili...
In recent years, orthopedic fixation devices have been widely used in the treatment of spinal injuries and deformities. In order to decrease the degree of these pathologies in theory, novel spinal motion preservation methods have been developed. In this study, the spine model of an adolescent idiopathic scoliotic patient was developed and the biome...
Spinal implant systems, which are used to facilitate fusion, correct deformities, and stabilize and strengthen the spine, are typically employed in surgical interventions on the spinal unit. The aim of this study was to investigate the biomechanical effect of a spinal implant system on the spinal unit model. A three-dimensional model of the lumbar...
Three-dimensional (3D) printing is a practical manufacturing method that allows us to transform objects designed in the digital environment into physical objects using layered manufacturing methods. The terms of rapid prototyping and additive manufacturing are also used to express the manufacturing process using 3D printers. Unlike the subtractive...
