High energy traumas could cause critical damage to bone, which will require permanent implants to recover while functionally integrating with the host bone. Critical sized bone defects necessitate the use of bioactive metallic implants. Because of bioinertness, various methods involving surface modifications such as surface treatments, the development of novel alloys, bioceramic/bioglass coatings, and biofunctional molecule grafting have been utilized to effectively integrate metallic implants with a living bone. However, the applications of these methods demonstrated a need for an interphase layer improving bone-making to overcome two major risk factors: aseptic loosening and peri-implantitis. To accomplish a biologically functional bridge with the host to prevent loosening, regenerative cues, osteoimmunomodulatory modifications, and electrochemically resistant layers against corrosion appeared as imperative reinforcements. In addition, interphases carrying antibacterial cargo were proven to be successful against peri-implantitis. In the literature, metallic implant coatings employing natural polymers as the main matrix were presented as bioactive interphases, enabling rapid, robust, and functional osseointegration with the host bone. However, a comprehensive review of natural polymer coatings, bridging and grafting on metallic implants, and their activities has not been reported. In this review, state-of-the-art studies on multifunctional natural polymer-based implant coatings effectively utilized as a bone tissue engineering (BTE) modality are depicted. Protein-based, polysaccharide-based coatings and their combinations to achieve better osseointegration via the formation of an extracellular matrix-like (ECM-like) interphase with gap filling and corrosion resistance abilities are discussed in detail. The hypotheses and results of these studies are examined and criticized, and the potential future prospects of multifunctional coatings are also proposed as final remarks.

Dual growth factor delivery using PLGA nanoparticles in silk fibroin/PEGDMA hydrogels for articular cartilage tissue engineering
Fathi-Achachelouei, Milad; Keskin, Dilek; Bat, Erhan; Vrana, Nihal E.; Tezcaner, Ayşen (Wiley, 2020-07-01)
Degeneration of articular cartilage due to damages, diseases, or age-related factors can significantly decrease the mobility of the patients. Various tissue engineering approaches which take advantage of stem cells and growth factors in a three-dimensional constructs have been used for reconstructing articular tissue. Proliferative impact of basic fibroblast growth factor (bFGF) and chondrogenic differentiation effect of transforming growth factor-beta 1 (TGF-beta 1) over mesenchymal stem cells have previou...
Resorbable PCEC/gelatin-bismuth doped bioglass-graphene oxide bilayer membranes for guided bone regeneration
Pazarçeviren, Ahmet Engin; Evis, Zafer; Keskin, Dilek; Tezcaner, Ayşen (IOP Publishing, 2019-05-01)
Guided bone regeneration (GBR) is a therapeutic modality applied prior to dental implant placement to increase bone density at the defect site or during placement for directing bone growth around implant. In this study, an asymmetric, bilayer structure was prepared by covalently bonding a dense polycaprolactone-polyethylene glycol-polycaprolactone (PCEC) membrane layer with a hydrogel layer composed of bismuth doped bioactive glass (BG, 45S5) and graphene oxide (GO) particles incorporated in gelatin. Struct...
Etiology of senile osteoporosis - A hypothesis
Atik, O. Sahap; Uslu, M. Murad; Eksioglu, Fatih; Satana, Tolgay (Ovid Technologies (Wolters Kluwer Health), 2006-02-01)
Osteoporosis is a major health problem characterized by compromised bone strength predisposing patients to an increased risk of fracture. It may cause morbidity and mortality in elderly men and women. The etiologic factors that lead to senile osteoporosis still are unclear.
Biodegradable polymer - hydroxyapatite nanocomposites for bone plate applıcations
Aydın, Erkin; Hasırcı, Vasıf Nejat; Planell, Joseph A.; Department of Biotechnology (2010)
Long bone fractures are fixed with bone plates to restrain movement of bone fragments. Fracture site must experience some pressure for proper healing. Bone plates are mostly made up of metals having 5 - 10 times higher elastic modulus than bones and most of the load is carried by them, leading to stress shielding and a bony tissue with low mineral density and strength. To avoid these problems, biodegradable polymer-based composite plates were designed and tested in this study. Poly(L-lactide) and Poly(3-hyd...
Development of clinoptilolite/poly ε-caprolactone -polyethylene glycol - poly ε-caprolactone triblock copolymer based scaffolds for bone tissue engineering
Pazarçeviren, Ahmet Engin; Tezcaner, Ayşen; Keskin, Dilek; Department of Engineering Sciences (2016)
Bone tissue engineering mainly depends on the feasible substitutes with ability to regenerate damaged bone tissue. One of the applications in which bone tissue engineering mainly focuses on is the production of bone tissue scaffolds. These scaffolds are expected to be biocompatible, highly interconnective and porous to provide a niche for colonizing bone cells. In addition, bone tissue scaffolds should be mechanically strong enough to accommodate compression. Scaffolds should also be biodegradable to encour...
