Special Issue Information

Dear Colleagues,

Nowadays, aspects of tribology concerned with biological systems and tribological properties of implantable biomaterials are extremely important, especially in situations where there is relative movement between the implanted biomaterials or between the implanted biomaterial and the natural tissue in physiological environments.

Recently, more and more innovative biomaterials, techniques (for example, 3D printing), and surface modification approaches have been introduced and, thus, their potential as implantable biomaterials and, furthermore, their biotribology and biotribocorrosion properties require investigation.

Moreover, to date, in silico wear prediction models of artificial human implants play a key role in the modeling of biotribological phenomena in the human body, justifying the growing interest of researchers in this direction.

This Special Issue aims to present a collection of manuscripts which may address, but not be limited to, the following topics:

(1) Experimental methods and mechanical measurements for characterizing the biotribology and biotribocorrosive properties of implantable biomaterials

(2) New emerging biomaterials for implantable clinical applications

(3) New emerging techniques for implantable clinical applications

(4) In silico (bio) tribological and (bio) tribocorrosion models of artificial implants

(5) Biomechanical modeling of the human body for determining the load conditions for artificial joints

(6) Surface modification for reduction of biotribology or biotribocorrosion of biomaterials

(7) Injected nanomaterials with enhanced lubrication properties

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. Applied Sciences is an international peer-reviewed open access semimonthly 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 2400 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.

Despite developments and advances in dental materials which allow for greater restorative performance, there are still challenges and questions regarding the formulation of new compositions and chemical reactions of materials used in restorative dentistry. The aim of this study was to assess and compare the mechanical and tribological characteristics of a bioactive resin, a composite resin, and a glass ionomer. Twenty specimens of each material were divided into two groups: one control group (n = 10), not subjected to thermocycling, and one test group (n = 10) submitted to thermocycling. The Vickers microhardness test was carried out and surface roughness was evaluated. The tribological sliding indentation test was chosen. The bioactive resin had the lowest hardness, followed by the composite resin, and the glass ionomer. The bioactive resin also showed greater resistance to fracture. For the tribological test, the wear rate was lower for the bioactive resin, followed by the composite resin, and the glass ionomer. The bioactive resin presented a smooth surface without visible cracks, while the other materials presented a brittle peeling of great portions of material. Thus, the bioactive resin performs better in relation to fracture toughness, wear rate and impact absorption than the composite resin and much better than the glass ionomer. Full article
