Special Issue Information

Dear Colleagues,

Biomaterials and biotechnologies play a pivotal role in advancing oral and maxillofacial surgery, addressing complex reconstructive and regenerative challenges. Biomaterials, including bioactive ceramics (e.g., hydroxyapatite and calcium phosphates), polymers (e.g., polylactic acid and collagen), and composites, are engineered to mimic the physical, chemical, and biological properties of native tissues. They support cellular adhesion, proliferation, and differentiation, crucial in bone regeneration, soft tissue repair, and implantology. Recent advancements have focused on designing biomaterials with controlled porosity, mechanical strength, and surface bioactivity to optimize osseointegration and reduce inflammation. Additionally, 3D printing and bioprinting technologies have enabled the precise fabrication of patient-specific scaffolds with complex geometries, enhancing functional outcomes. Moreover, the integration of biotechnologies, such as stem cell therapies, growth factors (e.g., BMP-2, TGF-β), and extracellular vesicles, has revolutionized tissue engineering by promoting targeted tissue regeneration. Biomarkers, including molecular signals of osteogenesis (e.g., alkaline phosphatase, osteocalcin) and angiogenesis (e.g., VEGF), are increasingly used to monitor the effectiveness of these therapies, providing insights into cellular responses and the microenvironment during healing. Collectively, these innovations aim to improve the predictability and longevity of reconstructive outcomes, reduce recovery times, and enhance the aesthetic and functional quality of life for patients. As the demand for personalized, regenerative approaches grows, this multidisciplinary field remains at the forefront of modern surgical practice.

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 250 words) can be sent to the Editorial Office for assessment.

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).

Background/Objectives: Sagittal split ramus osteotomy (SSRO) is a widely used method in the treatment of mandibular deformities. However, high parafunctional forces associated with bruxism can negatively affect stability at the osteotomy site. Botulinum toxin A (BoNT-A), which reduces masseter activity, is considered an additional approach to controlling these forces. Methods: In this comparative finite element study, five different fixation configurations were created on a three-dimensional mandibular model and evaluated under identical boundary conditions using both a 1000 N bruxism-related parafunctional loading and a standardized force-reduction scenario. The stress distributions and displacement amounts on the cortical bone, screws, and plates were examined in each model. Results: The stress distribution was more balanced in the model with double plates, whereas the stress and displacement values were found to be greater for fixations with single plates and only bicortical screws. Under the standardized force-reduction scenario, lower stress and displacement values were observed across all the models. Conclusions: Among the evaluated fixation configurations, the double-plate model demonstrated the most balanced stress distribution. Under the standardized force-reduction scenario, lower stress and displacement values were observed across all the models; these findings reflect the load sensitivity of the fixation constructs and should not be interpreted as evidence of clinical efficacy.
