Titanium implanthas been shown to be a predictable method for replacing missing teeth. Clinical studies revealed that implant failure rate in irradiated regionwas high. Many studies showed that modifications of implant surface could enhance implant osseointegration by improving cell attachment, cell growth and bone formation. Nevertheless, there were few studies investigating the effect of implant surface modification on osseointegration in irradiated bone. In the first experiment, the effect of fluoride-modified (FM) titanium surface on irradiated osteoblast attachment was assessed. The morphology and chemical composition of FM surface was assessed by SEM, AFM and XPS. Osteoblasts received 0Gy, 2Gy, 4Gy, 6Gy, 8Gy, 10Gy radiation. Cell number, fluorescence intensity and cell area of irradiated osteoblasts were assessed. The number of osteoblasts onFM surface was fewer than those on NF surface after 0Gy, 2Gy, 8Gy and 10Gy radiation. Cell area of osteoblasts on FM surface was less at 2Gy radiation but larger at 6Gy radiation than on NF surface. The fluorescence intensity of osteoblasts was also higher on NF surface than on FM surface after receiving 0Gy, 2Gy, 4Gy, 10Gy radiation. In the second experiment, an animal model was established to study the effect of radiation on osseointegration. Rabbits were divided into 15Gy and 30Gy radiation groups. Only the left leg was exposed to radiation, and the right leg was protected from radiation. Totally, 24 implants were inserted. Implant stability quotient (ISQ), bone volume to total volume (BV/TV), bone-to-implant contact (BIC), and bone growth rate were measured. After 15Gy and 30Gy of radiation, ISQ and BV/TV were significantly reduced. At week 3, 15Gy radiation group displayed slower bone growth rate comparing with the control side. Fluorochrome results showed that the 30Gy radiation side had a significantly slower apposition of new bone.In addition, BIC on30Gy radiation side was notablypoorer than that on 15Gy radiation side and on 30Gy control side. Based on the animal model, the third experiment investigated effects of calcium phosphate nanocrystals on implant osseointegration in irradiated bone. Titanium implants treated with nano-scale calcium phosphate (CaP) crystals served as the test group while ones with dual acid-etching only served as the control group. The left leg of rabbits received 15Gy radiation and implants were placed in the irradiated leg. Significant higher ISQ was detected in the nano-CaP group at week 12. The bone growth rate in nano-CaP group was more than doubled than the control group at both week 6 and week 9. The fourth experiment evaluated artifacts on micro-CT images caused by titanium dental implant. Implants were assigned into four groups: (1) implant only; (2) implant with covering screw; (3) implant with resin embedding; and (4) implant with covering screw and resin embedding. Each implant was scanned by micro-CT at 3 angulations. Implant angulation was the most determining factor followed by resin embedding. Minimal metallic artifacts were obtainedin non-embedded implants with its axis paralleling to X-ray. DOI: 10.5353/th_b5312315 Subjects: Osseointegration Dental implants

Download or read book Advanced Ceramics for Dentistry written by Martin Stefanic and published by Elsevier Inc. Chapters. This book was released on 2013-09-05 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-performance bioceramics, such as zirconia, alumina, and their composites, are attractive materials for the fabrication of load-bearing bone implants because of their outstanding mechanical properties, biocompatibility, corrosion resistance, and aesthetic quality. However, a lot of additional work is still needed on these ceramics before their full potential as implant materials can be exploited, especially in the area of surface optimization. The two most important issues relating to the surface of ceramic implants that need to be addressed are surface chemistry and topography. They both have an influence on protein adsorption and cell behavior and play a key role in providing sufficient biomechanical stability for the long-term success of implants. Therefore, extensive studies have been performed that are aimed at a better understanding of how specific surface modifications affect the biological response. In this chapter, various surface-modification techniques are described and their potential for improving the osseointegration of ceramic implants is discussed.

Download or read book Wetting Behavior of Dental Implants written by In-hye Kim and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Titanium (Ti) and titanium alloys are widely used in biomedical devices and components, because of their desirable properties, such as relatively low modulus, good fatigue strength, formability, machinability, corrosion resistance, and biocompatibility. However, Ti and its alloys cannot meet all of the clinical requirements. Therefore, surface modification of Ti has been often performed to improve the biological, chemical, and mechanical properties. Various modifications of surface properties have been investigated to predictably improve the osseointegration of Ti implants. The rate and quality of osseointegration in Ti implants are related to their surface properties. A multiplicity of implant surface forms exist engineered with mechanical features that physically interlock the implant with bone. Various strategies have been utilized to improve bone integration of Ti-based implants. For example, surface grit blasting, acid-etching and anodization methods enhance cell growth, improving implant fixation through increases in interlocking surface area and alterations of oxide thickness. On the other hand, surface composition and hydrophilicity are parameters that may play a role in implant-tissue interaction and osseointegration. Highly hydrophilic surfaces seem more desirable than hydrophobic ones in view of their interactions with biological fluids, cells and tissues. Several recent studies have shown that the surface energy of biomaterials strongly has influence the initial cell attachment and spreading of osteoblastic cells on the biomaterial surfaces. Hallab and others said that surface energy might be a more important determinant of cell adhesion and proliferation, and might be more useful than surface roughness for generating cell adhesion and cell. It may have the influence on protein adsorption and the structural rearrangement of the proteins on the material. Therefore, understanding the relationship between surface energy and cell adhesion on different biomaterials will facilitate the design of optimized implant material surfaces and subsequently the cell attachment. Surface energy is an important parameter of the material surface. It is affected by several surface characteristics, such as chemical composition, surface charge, and microstructural topography. Many papers reported that surface energy is one of important surface characteristics parameter of modified titanium surfaces. Given the importance of surface wettability of dental implants surfaces in the achievement of osseointegration, the surface free energy values for a given material, obtained by various methods and with use of different measuring liquids, are not consistent. Thus, we provided a review article of the surface modification on titanium surface and the surface wettability. The relationship between CAs and surface preparations was determined in this review.

Download or read book Bionanomaterials for Dental Applications written by Mieczyslaw Jurczyk and published by CRC Press. This book was released on 2012-10-26 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces readers to the structure and characteristics of nanomaterials and their applications in dentistry. With currently available implant materials, the clinical failure rate varies from a few percent to over 10 percent and new materials are clearly needed. Nanomaterials offer the promise of higher strength, better bonding, less toxicity, and enhanced cytocompatibility, leading to increased tissue regeneration. Mieczyslaw Jurczyk, director of the Institute of Materials Science and Engineering at the Poznan University of Technology in Poland, has drawn from work in his laboratory and elsewhere in Poland to show that nanomaterials have important biological applications including in the stomatognathic system consisting of mouth, jaws, and associated structures. The book is written from a materials science and medical point of view and has 13 chapters and about 400 pages. The book can be divided approximately into three sections: the first five chapters introduce nanobiomaterials, the next five chapters describe their dental applications, and the last chapters describe their biocompatibility. Chapter 3 is a compendium on metallic biomaterials such as stainless steel, cobalt alloys, and titanium alloys; bioactive, bioresorbable polymers; and composites and ceramic biomaterials. The "top-down" approach to producing nanomaterials such as high-energy ballmilling and severe plastic deformation, as well as Feynman’s "bottom-up technique" of building atom by atom, are discussed in the next chapter. Subsequent chapters discuss each material in depth and point out how new architectures and properties emerge at the nanoscale. Chapter 8 is devoted to shape-memory materials, which now include not only NiTi but also polymers and magnetic materials. In order to improve bonding, nanomaterials can be used to synthesize implants with surface roughness similar to that of natural tissues. Chapter 9 is devoted to different surface treatments for Ti-based nanomaterials, such as anodic oxidation to improve the bioactivity of titanium and improve the corrosion resistance of porous titanium and its alloys. The use of carbon in various forms—nanoparticles, nanofibers, nanotubes, and thin films—is discussed next with emphasis on the microstructure and properties of these materials, their implant applications, and their interaction with subcutaneous tissues. Nanomaterials can be used in preventive dentistry and therefore can reduce the amount of dental treatment that is necessary to maintain a healthy mouth as argued in chapter 11. In a subsequent chapter, the author explains osseointegration (direct bone-to-metal interface) from a biological point of view and early tissue response. The mechanism of the interaction between the implanted materials with the cellular protein in the tissues is described. The last chapter discusses the application of new nanostructured materials in permanent and bioresorbable implants, nanosurface dental implants, and nanostructured dental composite restorative materials. This book not only focuses on nanomaterials but also on nanoengineering to achieve the best results in dentistry. It is recommended to anyone interested in nanomaterials and their applications in dental science. People with a background in materials, chemistry, physics, and biology will benefit from it.
