Special Issue Information

Dear Colleagues,

It is with great pleasure that I invite you to contribute to the Special Issue titled "Biomechanical Studies and Biomaterials in Dentistry" in the Journal of Functional Biomaterials. The integration of biomechanics and biomaterials in dentistry has led to significant advancements, resulting in improved patient outcomes and innovative treatment approaches. With the advent of cutting-edge technologies and novel materials, the dental field is experiencing a paradigm shift towards more personalized and effective treatments. This Special Issue aims to feature these advancements by introducing the latest research and developments from around the world, providing a platform for high-quality studies that push the boundaries of current knowledge and practice in dental biomechanics and biomaterials.

This Special Issue aims to explore the latest research and developments in this interdisciplinary area. The focus includes, but is not limited to, the following topics:

  1. Biomechanical analysis: studies on the mechanical properties of dental materials and their behavior under various physiological conditions.
  2. Innovative biomaterials: development and characterization of new biomaterials that enhance dental treatments and patient comfort.
  3. Clinical applications: case studies and clinical trials showcasing the application of biomechanical principles and advanced biomaterials in dental practice.
  4. Computational modeling: use of computational tools to simulate and predict the performance of dental biomaterials in clinical scenarios.
  5. Regenerative dentistry: research on biomaterials that supports tissue regeneration and repair within the oral cavity.
  6. Nanotechnology in dentistry: exploration of nanomaterials and their potential to revolutionize dental treatments.

Through this Special Issue, we aim to bring together researchers, clinicians, and industry professionals to share their insights and findings. We invite authors to submit original research articles and comprehensive reviews that align with the theme of this Special Issue. Together, let us advance the frontiers of dental biomaterials and biomechanics for the benefit of patients and the broader medical community.

The aim of the study is to assess the impact of mechanical surface treatments on the shear bond strength (SBS) of orthodontic brackets bonded to three-dimensional (3D) printed and milled CAD/CAM provisional materials. Sixty cylindrical samples were fabricated for each provisional material. Samples were treated with one of the following surface treatments: aluminum oxide airborne particle abrasion, diamond bur rotary instrument roughening, and phosphoric acid etching (control). Stainless steel brackets were bonded to the samples, and then SBS was tested using a universal testing machine. SEM and digital microscopy were utilized to examine the bonding interface and the failure modes. Two-way ANOVA, one-way ANOVA, Tukey’s HSD, and independent sample t-tests were used for statistical analysis. Results revealed significant differences in SBS between 3D printed and milled samples and significant differences in SBS among most surface treatments, with rotary instrument roughening resulting in the highest values for 3D printed, while airborne particle abrasion leading for milled samples. Digital microscopy indicated that more adhesive remained on 3D-printed samples. SEM analysis revealed varying surface roughness across treatments. Based on the findings of this study, it can be concluded that different surface treatments improve the bonding of orthodontic brackets to provisional crowns. Full article

(1) Background: This study aimed to enhance the biological properties of hydraulic calcium silicate cements (HCSCs) by incorporating organic and inorganic components, specifically elastin-like polypeptides (ELPs) and bioactive glass (BAG). We focused on the effects of these composites on the viability, migration, and osteogenic differentiation of human periodontal ligament fibroblasts (hPDLFs). (2) Methods: Proroot MTA was supplemented with 1–5 wt% 63S BAG and 10 wt% ELP. The experimental groups contained various combinations of HSCS with ELP and BAG. Cell viability was assessed using an MTT assay, cell migration was evaluated using wound healing and transwell assays, and osteogenic activity was determined through Alizarin Red S staining and a gene expression analysis of osteogenic markers (ALP, RUNX-2, OCN, and Col1A2). (3) Results: The combination of ELP and BAG significantly enhanced the viability of hPDLFs with an optimal BAG concentration of 1–4%. Cell migration assays demonstrated faster migration rates in groups with 2–4% BAG and ELP incorporation. Osteogenic activity was the highest with 2–3% BAG incorporation with ELP, as evidenced by intense Alizarin Red S staining and the upregulation of osteogenic differentiation markers. (4) Conclusions: The incorporation of ELP (organic) and BAG (inorganic) into HCSC significantly enhances the viability, migration, and osteogenic differentiation of hPDLFs. These findings suggest that composite HCSC might support healing in destructed bone lesions in endodontics. Full article

Background: Removable prostheses have seen a fundamental change recently because of advances in polymer materials, allowing improved durability and performance. Despite these advancements, notable differences still occur amongst various polymer materials and processing technologies, requiring a thorough grasp of their mechanical, physical, and therapeutic implications. The compressive strength of dentures manufactured using various technologies will be investigated. Methods: Traditional, injection molding, and additive and subtractive CAD/CAM processing techniques, all utilizing Polymethyl methacrylate (PMMA) as the main material, were used to construct complete dentures. The specimens underwent a compressive mechanical test, which reveals the differences in compressive strength. Results: All the specimens broke under the influence of a certain force, rather than yielding through flow, as is characteristic for plastic materials. For each specimen, the maximum force (N) was recorded, as well as the breaking energy. The mean force required to break the dentures for each processing technology is as follows: 4.54 kN for traditional packing-press technique, 17.92 kN for the injection molding technique, 1.51 kN for the additive CAD/CAM dentures, and 5.9 kN for the subtractive CAD/CAM dentures. Conclusions: The best results were obtained in the case of the thermoplastic injection system and the worst results were recorded in the case of 3D printed samples. Another important aspect depicted is the standard deviation for each group, which reveal a relatively unstable property for the thermoplastic injected dentures. Good results here in terms of absolute property and stability of the property can be conferred to CAD/CAM milled group. Full article
