Special Issue Information

Dear Colleagues,

The evolution of resinous materials in fixed prostheses on implants and teeth has led to high-level results, both in terms of aesthetics and in terms of durability. The possibility of producing these materials with completely digital laboratory methods, associated with completely digital studio workflows, allows the reduction of processing times and the possibility of delivering complex but cheaper prosthetic restorations. The possibility of using resinous materials that do not require metal reinforcements allows us to reduce costs, improve aesthetics and reduce processing times.

Moreover, the possibility of being able to choose different techniques for working the product makes the choice of this type of material for different applications very interesting, and with particular attention to fully digital workflows. To date, substructures of implant prostheses supported in zirconia, structures coated with other types of resins, complete resins or even milled digital flow complete dentures represent absolutely remarkable technical possibilities, and capable of attracting the attention of researchers, in developing new products, and of clinicians, in testing new materials already on the market or with interesting evaluations to improve the production of new products.

Hoping to have caught your attention, we expect to receive manuscripts that can enrich our knowledge in this area.

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. Journal of Composites Science 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 1800 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.

Polyetheretherketone (PEEK) is considered one of the most innovative prosthetic materials of the last few decades. Its chemically inert behavior and high biocompatibility make it a promising material in many areas of dentistry. The aim of this study was to test whether PEEK with different TiO2 filler contents achieves comparable bond strength values when using different resin cements. N = 70 PEEK samples each with different TiO2 filler content (20 wt.% TiO2 vs. 5 wt.% TiO2 vs. no filler as a control group) were divided into seven groups and cemented with various conventional (ResiCem, RelyX Ultimate, Variolink Esthetic DC) and self-adhesive resin cements (RelyXUnicem 2, Bifix SE, Panavia SA Cement Plus, SpeedCem). The shear strength of the bond was assessed after 24 h and after 25,000 thermal loading cycles. Mann-Whitney U and Wilcoxon tests were used for statistical analysis (significance level: α = 0.05). PEEK without filler showed the highest mean shear strength (24.26 MPa using RelyX Ultimate), then high-filled PEEK (22.90 MPa using ResiCem) and low-filled PEEK (21.76 MPa using RelyX Ultimate). Conventional resin cements generally achieved slightly higher adhesive strengths than self-adhesive resin cements. It appears that the filler content does not affects the adhesive bond strengths.
