Special Issue Information

Dear Colleagues,

Implantable materials have become the focus of recent intense research due to longer life expectancy and, thus, an increased need for replacing organs or tissues lost after injuries and/or trauma. Several types and models of novel implantable materials have been proposed, necessitating studies evaluating their behavior in vitro and in vivo and their characteristics, applicability and predictability. Such research will help professionals in choosing the best rehabilitative materials for each unique clinical situation.

The properties of biomaterials and scaffolds, such as pore structures, mechanical properties and degradation, play an essential role in their successful implementation for tissue repair or regeneration. The surface characteristics of biomaterials, e.g., their topography, chemistry or surface energy, are also crucial for cell-material interaction and implant integration.

We are interested in articles that explore novel dental implant materials. Potential topics include, but are not limited to, the following:

  • The synthesis and characterization of novel dental implant materials;
  • Implant material design;
  • Synthesis and characterization of bone substitutes and membranes;
  • Tissue engineering;
  • Bone tissue-material interaction;
  • In vitro and in vivo assays.

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.

(1) Background: The present pilot in vitro study evaluated, physically and biologically, the effects produced by the wear of the titanium surface using different drill models. (2) Methods: Titanium disks were subjected to wear using four different burs and accordingly divided into the following test groups (n = 12 disks per group): Tungsten Burs (TB group), Tungsten Carbide Burs (TCB group), Coarse-Grained Diamond Burs (CGB group), and Fine-Grained Diamond Burs (FGB group). As a control group (CON group), titanium disks with a smooth surface (machined) were used. The samples were subjected to atomic force microscopy (AFM), profilometry analysis, scanning electron microscopy (SEM), and cell viability and adhesion assessments. (3) Results: The values of the measured roughness parameters showed statistical differences among the five groups (p = 0.0035 for Ra and p = 0.0010 for Rz). All test groups showed an important difference statistically (p = 0.0032) to the CON group for the cell viability and adhesion analysis. The data of cell absorbance at 570 nm were 0.4122 ± 0.05 for the CON group, 0.1354 ± 0.02 for the TB group, 0.123 ± 0.01 for the TCB group, 0.1414 ± 0.02 for the CGB group, and 0.1216 ± 0.03 for the FGB group. Additionally, the cell count showed the following adherence percentages: 57.6 ± 4.6% for the CON group, 22.9 ± 3.3% for the TB group, 23.4 ± 2.9% for the TCB group, 22.5 ± 3.1% for the CGB group, and 23.7 ± 3.3% for the FGB group. However, no statistical differences were found among the four test groups analyzed (p = 0.3916). (4) Conclusions: The results showed that the changes produced on the surface by the four different bur models altered the topography characteristics and affected the cell viability and adhesion in comparison with the control group.
