To obtain TiNi foams with interconnected pores that have surface quality necessary for bone growth in addition to required mechanical performance, sintering with the space holder technique was employed in this study, which aimed to evaluate the bone healing process of TiNi graft materials. For this purpose, processed TiNi foams with three different porosities were placed into the created defects in the femur of rats. Moreover, the mechanical properties of the processed TiNi foams were conducted via monotonic compression tests in order to evaluate mechanical biocompatibility.

The aim of this study was to obtain a biocompatible and antimicrobial implant surface by coating Ti6Al4V with chitosan which can be used to create a smooth transmucosal region for a faster and better wound healing and an increased bioactivity. Ti6Al4V plates were first abraded and ultrasonically cleaned and then coated with chitosan. In order to simulate the conditions of an oral environment, a group of coated plates were treated in a thermocycle apparatus. The coatings were evaluated with SEM, EDS, XRD and...
A novel biodegradable PCL film for tendon reconstruction: Achilles tendon defect model in rats
Kazimoglu, C; Bolukabsi, S; Kanatli, U; Senkoylu, A; Altun, NS; Babac, C; Yavuz, H; Piskin, E (2003-09-01)
This study aims to investigate applicability of poly(E-caprolactone) (PCL) biodegradable films for repair of gaps in Achilles tendons in a rat model, also comparing surgical repair versus no repair approaches. PCL was synthesized with tailor-made properties, then, PCL films were prepared by solvent casting. Seventy-five outbred Sprague-Dawley rats were randomly allocated into five groups: (i) sham operated (skin incision only); (ii) no repair (complete division of the Achilles tendon and plantaris tendon wi...
The evaluation of some flexural properties of a denture base resin reinforced with various aesthetic fibers
DOĞAN, ORHAN MURAT; Bolayir, Giray; Keskin, Selda; DOĞAN, ARİFE; Bek, Buelent (Springer Science and Business Media LLC, 2008-06-01)
This study was performed to determine whether some flexural properties of a denture base resin material could be improved through reinforcement with five types of aesthetic fibers at 3% concentration by weight and in 2, 4, and 6 mm length. Five specimens of similar dimensions were prepared for each of the test groups; base resin and the same resin with glass, rayon, polyester, nylon 6 and nylon 6,6 fibers in three different lengths. Flexural properties were evaluated by using a 3-point bending test. A visua...
The Relationship Between Arthroplasty Surgeons' Experience Level and Optimal Cable Tensioning in the Fixation of Extended Trochanteric Osteotomy
Başarır, Kerem ; Kalem, Mahmut ; Şahin, Ercan; Özbek, Emre Anıl; Karaca, Mustafa Onur ; Kucukkarapinar, Ibrahim; Tönük, Ergin (2021-12-01)
Introduction: In this study, our aim was to examine the relationship between the arthroplasty surgeons' experience level and their aptitude to adjust the cable tension to the value recommended by the manufacturer when asked to provide fixation with cables in artificial bones that underwent extended trochanteric osteotomy (ETO). Materials and Methods: A custom-made cable tensioning device with a microvoltmeter was used to measure the tension values in Newtons (N). An ETO was performed on 4 artificial femur b...
Preparation and characterization of poly(epsilon-caprolactone) scaffolds modified with cell-loaded fibrin gel
Malikmammadov, Elbay; Endoğan Tanır, Tuğba; Kızıltay, Aysel; Hasırcı, Nesrin (2019-03-15)
Poly(epsilon-caprolactone) (PCL) is one of the most commonly used polymers in the production of tissue engineered scaffolds for hard tissue treatments. Incorporation of cells into these scaffolds significantly enhances the healing rate of the tissue. In this study, PCL scaffolds were prepared by wet spinning technique and modified by addition of fibrinogen in order to form a fibrin network between the PCL fibers. By this way, scaffolds would have micro and nanofibers in their structures. Drying of the wet s...
