“…The shape memory effect is a unique phenomenon in which the deformed material has the ability to recover to its original shape and size when heated in a special characteristic temperature range or as a response to mechanical stresses by a reversible martensitic transformation. This impressive feature bequeaths the SMA many applications, especially in medical and spine surgeries[ 134 - 136 ]. Moreover, the SMAs also have other stimulating uses in actuators, sensors, the aerospace industry, and even fashion products[ 137 ].…”

Additive manufacturing (AM) is among the most attractive methods to produce implants, the processes are very swift and it can be precisely controlled to meet patient’s requirement since they can be produced in exact shape, dimension, and even texture of different living tissues. Until now, lots of methods have emerged and used in this field with diverse characteristics. This review aims to comprehensively discuss 3D printing (3DP) technologies to manufacture metallic implants, especially on techniques and procedures. Various technologies based on their main properties are categorized, the effecting parameters are introduced, andthe history of AM technology is briefly analyzed. Subsequently, the utilization of these AM-manufactured components in medicine along with their effectual variables is discussed, and special attention is paid on to the production of porous scaffolds, taking pore size, density, etc., into consideration. Finally, 3DP of the popular metallic systems in medical applications such as titanium, Ti6Al4V, cobalt-chromium alloys, and shape memory alloys are studied. In general, AM manufactured implants need to comply with important requirements such as biocompatibility, suitable mechanical properties (strength and elastic modulus), surface conditions, custom-built designs, fast production, etc. This review aims to introduce the AM technologies in implant applications and find new ways to design more sophisticated methods and compatible implants that mimic the desired tissue functions.

Öz Şekil hafızalı alaşımlar ilgi çekici özelliklerinden dolayı birçok mühendislik uygulaması için potansiyel oluşturmaktadır. Mühendisliğe ek olarak, özellikle NiTi şekil hafızalı alaşımlarının mekanik özelliklerinin yanında biyouyumlu olmasından dolayı biyomedikal alanında da yaygın olarak kullanılabilmekte ve imalat maliyetlerinin düşmesi ile orantılı olarak kullanım oranının artacağı tahmin edilmektedir. Bu derleme makalesinde şekil hafızalı alaşımların genel özelliklerinden kısaca bahsedilmekte ve daha sonra bu alaşımların diş hekimliği, ortopedi ve genel cerrahi uygulamaları tanıtılmaktadır.

“…Nitinol braces are more flexible, lightweight, and have a better shape memory than conventional braces, which can improve patient comfort and compliance. Additionally, Nitinol braces can exert a continuous and controlled corrective force on the spine, which can prevent the progression of the curvature and reduce the need for surgery [ [17] , [18] , [19] ]. Wang et al (2011) conducted a retrospective study on the clinical and radiological outcomes of using a Nitinol shape memory alloy rod for the treatment of scoliosis [ 17 ].…”

“…The study demonstrated the potential of using Nitinol shape memory alloys in the treatment of scoliosis, providing a promising alternative to traditional treatment methods. Sánchez et al (2012) induced structural experimental scoliosis in a rat model by tethering sutures between the left scapula and pelvis [ 18 ]. The scoliosis and resulting structural deformities of the vertebrae were then gradually corrected using a shape-memory alloy wire attached to the spine after the posterior tether was removed.…”
