Special Issue Information

Dear Colleagues,

This Special Issue aims to enumerate the trends and prospects of orthodontic treatment that will determine the future of orthodontics. With the advent of technology and materials and with a better understanding of growth and development in the orthodontic field, orthodontic treatment will be more effective, efficient, and patient-friendly. The key trends and prospects are digital orthodontics, temporary skeletal anchorage devices (TSADs), cone-beam computed tomography (CBCT), 3D technology, clear aligners, invisible braces, accelerated orthodontics, artificial intelligence, interdisciplinary approaches, preventive orthodontics, eco-friendly practices, teledentistry, personalized orthodontic care, and educational content for patients and orthodontic professionals. Therefore, in this Special Issue, we invite several authors to contribute articles exploring the current trends and long-term prospects of orthodontic treatment.

Prof. Dr. Jong-Moon Chae
Guest Editor

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). 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.

The objective of the present study was to investigate whether orthodontic treatment alters the morphology and bone mineral density (BMD) distribution of the mandibular condyle in growing adolescent patients. Cone-beam computed tomography (CBCT) images were retrospectively analyzed for 29 patients (10 males and 19 females, aged 12.5 to 17.0 years) treated with full fixed orthodontic appliances. The right and left mandibular condyles were digitally isolated. For the internal control sample, the basal cortical bone (CB) at both mandibular first molar sites was also digitally dissected. A frequency plot of the CBCT gray values, proportional to BMD, was analyzed to calculate the mean and the 5th percentile of low and high gray values (Low5 and High5). Morphological changes in the condylar surface were assessed based on temporomandibular joint osteoarthritis (TMJOA) counts. Lateral cephalometric radiographs were used to measure facial morphology parameters and classify skeletal patterns. The cervical vertebral gray values of the same patients were compared. No radiographic signs of TMJ disorder were observed with no significant difference in TMJOA counts between before and after treatment (p = 0.56). The volume, mean and Low5 gray values of the mandibular condyle, facial morphology parameters, and cervical vertebral gray values significantly increased following orthodontic treatment (p < 0.05). Skeletal Class II patients exhibited greater changes in mean, Low5, and High5 mandibular condyle gray values compared to their Class I patients (p < 0.05), whereas cervical vertebral gray values were not significantly influenced by skeletal classification (p > 0.19). The findings suggest that orthodontic treatment, combined with natural patient growth, contributes to nonpathological condylar alterations in adolescent patients. Full article

Background: This meta-analysis aimed to evaluate the dentoalveolar changes of miniscrew-assisted rapid palatal expansion (MARPE) compared with conventional rapid palatal expansion (CRPE) in growing patients (≤16 years). Methods: A systematic and comprehensive literature search was carried out independently by two reviewers using both MeSH terms and free-text keywords across PubMed, the Cochrane Library, and Embase, with studies published through February 2025 included. The risk of bias was assessed using the Cochrane ROB 2.0 tool. The GRADE system was employed to determine evidence quality. Results: Of the 462 initially screened articles, 6 met the inclusion criteria and were selected for quantitative synthesis. Most studies had a low risk of bias with some concerns in reporting. The pooled standardized mean difference (SMD) for tooth inclination changes in CRPE compared with MARPE was 0.98 (95% confidence interval (CI), 0.54 to 1.42; p < 0.01). The test for overall effect was significant (p < 0.01), but no significant differences were found between the subgroups. The pooled SMD for buccal bone thickness changes in CRPE compared with MARPE was 0.69 (95% CI, 0.37 to 1.00; p < 0.01). The test for overall effect was significant (p < 0.01), and there were substantial differences between the subgroups. The supporting evidence ranged in certainty from moderate to low. Conclusions: MARPE was more effective than CRPE in minimizing the buccal tipping and buccal bone loss of the maxillary first premolars and first molars. However, to further confirm these outcomes and guide evidence-based clinical practice, well-designed randomized controlled trials with long-term follow-up are necessary. Full article
