Ceramic Dental Implants: Concept, Fabrication, Mechanical and Biological Properties

Dear Colleagues,

In the last several decades, ceramics have gained significant relevance in the dental implants market; firstly, in porcelain fused to metal (PFM) and further substitution for zirconia crowns in all-ceramic restoration.

The global dental implants market is expected to reach $5.9 billion by 2028. Currently, zirconia materials are a particular focus of the most influential dental implant companies around the world, which are producing zirconia dental implants.

In comparison with titanium alloy implants, zirconia dental implants are better at avoiding bacterial biofilm accumulation and do not have the drawbacks of corrosion and allergic reactions, and further provide aesthetic value. However, the mechanical properties mismatch between zirconia and jawbone can highlight the typical problems of bone–implant contact and jaw osteonecrosis. Promising solutions to minimize these effects could improve antibacterial self-defense conditions and avoid future peri-implantitis.

Moreover, 3D-printing techniques are gaining interest in association with ceramic dental implants designed as tailored surfaces and structural solutions.

According to the potential of ceramics in dental applications, the present Special Issue serves to analyze comprehensive solutions in dental ceramics, mainly focused on zirconia dental implants or ceramic composites solutions. The current Special Issue will focus on several topics, including 3D-printing techniques, surface roughness, bioactive and antibacterial functional surfaces, functionally graded solutions, biomechanical optimization, experimental tests, and simulation and computational models for structural analysis.

It is our pleasure to invite you to submit a manuscript or review paper to this Special Issue of Materials.

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).
