Finite element investigation of mechanical interaction of dental implants with bone

Eser, Atılım
During the last years, biomechaniccs, the understanding of the very complex mechanical behavior of living tissue, becomes a very important field of research of the wide bravch of mechanichs. Thia study is very important, for instance , to improve the design of implants, with the important social and economical impact. one of important challenges in implant design is to model the complex material behavior of the bone. Remodeling of the bone due to the lodaing is one of the essential behaviors of the bone which can cause for the dental implants, marginal bone loss accuring particallary in the first years of function. On the other hand the finite element method(FEM) has become the most extended tool for engineers to analyse the mechanical behavior of the products which usualy have a complex material behavior and complicated geometries. The aim of this study is to model the remodeling behavior of the bone using FEM and to use the new bone material method to evaluate the implant performance for some commercial implants, taking account of the bone adaptation.


Electro-magnetic source imaging using realistic head models
Akalın Acar, Zeynep; Gençer, Nevzat Güneri; Department of Electrical and Electronics Engineering (2005)
Electro-Magnetic Source Imaging (EMSI) is the estimation of the position, orientation and strength of active electrical sources within the brain from electrical and magnetic measurements. For an accurate source localization, the head model must correctly represent the electrical and geometrical properties of the head. To solve the forward problem using realistic head models numerical techniques must be used. This work uses the Boundary Element Method (BEM) for solving the forward problem. The accuracy of th...
Integrated biomimetic scaffolds for soft tissue engineering
Güven, Sinan; Hasırcı, Nesrin; Department of Biotechnology (2006)
Tissue engineering has the potential to create new tissue and organs from cultured cells for transplantation. Biodegradable and biocompatible scaffolds play a vital role in the transfer of the cultured cells to a new tissue. Various scaffolds for soft tissue engineering have been developed, however there is not any structure totally mimicking the natural extracellular matrix (ECM), ready to use. In this study biodegradable and biocompatible scaffolds were developed from natural polymers by tissue engineerin...
Native extracellular matrix/fibroin hydrogels for adipose tissue engineering with enhanced vascularization
Kayabolen, Alisan; Keskin, Dilek; Aykan, Andac; Karslioglu, Yildirim; Zor, Fatih; Tezcaner, Ayşen (IOP Publishing, 2017-06-23)
Adipose tissue engineering is a promising field for regeneration of soft tissue defects. However, vascularization is needed since nutrients and oxygen cannot reach cells in thick implants by diffusion. Obtaining a biocompatible scaffold with good mechanical properties is another problem. In this study, we aimed to develop thick and vascularized adipose tissue constructs supporting cell viability and adipose tissue regeneration. Hydrogels were prepared by mixing rat decellularized adipose tissue (DAT) and si...
Scale up of panel photobioreactors for hydrogen production by PNS Bacteria
Avcıoğlu, S. Gökçe; Eroğlu, İnci; Özgür, Ebru; Department of Chemical Engineering (2010)
Production of hydrogen from biomass through the use of dark and photofermentative bacteria will be applicable in the future and a promising route. The aim of this study is to develop and to scale-up solar panel photobioreactors for the biological hydrogen production by photosynthetic purple non sulfur (PNS) bacteria on artificial substrates and on real dark fermentation effluent of molasses. The parameters studied are light intensity, temperature, feed stock, feed rate, pH, cell density, light and dark cycl...
Realization of a cue based motor imagery brain computer interface with its potential application to a wheelchair
Akıncı, Berna; Gençer, Nevzat Güneri; Department of Electrical and Electronics Engineering (2010)
This thesis study focuses on the realization of an online cue based Motor Imagery (MI) Brain Computer Interface (BCI). For this purpose, some signal processing and classification methods are investigated. Specifically, several time-spatial-frequency methods, namely the Short Time Fourier Transform (STFT), Common Spatial Frequency Patterns (CSFP) and the Morlet Transform (MT) are implemented on a 2-class MI BCI system. Distinction Sensitive Learning Vector Quantization (DSLVQ) method is used as a feature sel...
