Special Issue Information

Dear Colleagues,

It is a matter of great pleasure to invite you to contribute to the present Special Issue on “Ceramic Materials for Biomedical Applications”.

Ceramic materials can be used in many ways with different purposes. The ceramics, used mainly in biomedical fields, are called bioceramics or bioglasses. Generally, bioceramics are closely related to either the composition of hard tissues in human bodies or are extremely durable metal oxides. Bioceramics are used in various types of medical procedures, and as such, they have to meet strict requirements with regard to their physical and chemical properties and biocompatibility. Bioceramics can also be sorted into different types, such as ceramic oxides, which are compatible with the human body, or resorbable ceramic materials, which will be eventually supplanted by the body after they have played their role in the healing process. Ceramics have been successfully used for more than twenty years as orthopaedic prostheses and are characterized by low friction coefficient and low wear rate, compared to metallic materials (stainless steels, titanium, and chromium–cobalt alloys). However, they have much higher brittleness than that of metals, and this restricts the use of ceramics in load bearing implants. This disadvantage can be overcome by developing composite materials with combination of two different materials. In composites, the dispersed phases can increase the fracture toughness and mechanical characteristics of ceramics.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Coatings is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Zirconia, with its excellent mechanical strength and esthetics, has a growing potential for applications in dentistry and orthopedics. However, in order for zirconia to have a high affinity with bone tissue, the bioactivity of the surface must be further increased. In order to increase the bioactivity of zirconia, research was conducted to make a porous support or to fill the porous structure with nano-hydroxyapatite (nHA). In this case, there is a risk that physically filled nHA could be released depending on the living environment. In this study, nHA and type I collagen were introduced to the zirconia surface by chemical covalent bonding to increase bioactivity and ensure safety in the body. The chemical reaction of the surface was confirmed by X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FE-SEM) and Fourier transform infrared (FT-IR) spectroscopy. In addition, the biological activity was evaluated by examining the cytotoxicity and bone formation ability of the modified zirconia using osteoblasts. As a result, it was found that the bioactivity of the zirconia surface was greatly improved by immobilizing nHA and type I collagen. Full article
