Special Issue Information

Dear Colleagues,

We are currently inviting submissions to this Special Issue, titled “Mechanical Properties of Dental Materials”. The mechanical properties of dental materials play a crucial role in determining the longevity and performance of dental restorations. Attributes such as durability, strength, wear resistance, and biocompatibility are essential for withstanding the forces of mastication and the harsh oral environment.

We welcome the submission of manuscripts that explore the mechanical properties of materials used in dental restorations, including, but not limited to, amalgam, composites, ceramics, and alloys. Topics of interest include tensile strength, compressive strength, elasticity, fatigue resistance, and thermal expansion coefficients, as well as their impact on the performance and longevity of dental materials.

We encourage authors to submit original research, review articles, and case studies that contribute to our understanding of how mechanical properties influence the clinical success of dental restorations. Submissions that address the relationship between mechanical properties and biocompatibility are particularly welcome.

We look forward to receiving your manuscripts and contributing to the advancement of knowledge in this important area of dental materials science.

Dr. Rodrigo França

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. Materials 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 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.

Measuring the flexural strength of restorative materials such as zirconia is crucial for providing proper indications for clinical applications and predicting performance. Great variations in specimen preparation for flexural strength measurements exist among laboratories. The aim was to evaluate how the processing method, surface treatment, and test method of the specimens affect the flexural strength of zirconia. Zirconia specimens (VITA YZ HT) (n = 270) were processed using CAD/CAM or were conventionally milled with three different surface treatments (machined, ground, polished) and were measured with three-point bending (non-chamfered/chamfered) or biaxial flexural strength test. Weibull statistics were conducted. The mean flexural strength values ranged from 612 MPa (conventional, machined, three-point bending non-chamfered) to 1143 MPa (CAD/CAM, polished, biaxial flexural strength). The highest reliability is achieved when specimens are prepared using thoroughly controllable processing with CAD/CAM and subsequently polished. Higher strength values are achieved with the biaxial flexural strength test method because the stress concentration in relation to the effective volume is smaller. Polishing reduces surface microcracks and therefore increases the strength values. Full article
