Recently, the use of orthodontic mini-screws as an anchorage for orthodontic treatment is increasing, and the degree of osseointegration of the mini-screws affects the performance of orthodontic treatment. This study aimed to evaluate the biocompatibility and osseointegration of Titanium 6Aluminum 4Vanadium (Ti-6Al-4V) alloy orthodontic mini-screws with an ibandronate-loaded TiO nanotube (TNT) layer. The TNT layer was formed on the surface of the Ti-6Al-4V alloy orthodontic mini-screws and loaded with ibandronate. The TNT formed by anodic oxidation formed a completely self-organized and compact structure and was stably released for 7 days after loading with ibandronate. Mini-screws loaded with ibandronate were implanted into both tibias of rats, confirming rapid initial bone regeneration. We demonstrate that the release of stable ibandronate from the TNT layer of Ti-6Al-4V alloy orthodontic mini-screws can effectively improve biocompatibility and osseointegration.

Objectives: This umbrella meta-analysis aimed to answer the clinical question: Do mini-screws and micro-implants improve specific orthodontic outcomes such as intermolar width, interpremolar width, suture expansion, molar movement, and skeletal width compared to conventional anchorage methods?
Materials And Methods: A systematic search was performed in PubMed, Scopus, ISI Web of Science, and Google Scholar up to October 2024. Systematic reviews and meta-analyses on mini-screws and micro-implants in orthodontic treatment were included. Methodological quality was assessed using AMSTAR 2, and a random-effects model was used to calculate effect sizes (ESs) and 95% confidence intervals (CIs).

Objective: To compare the levels of interleukin (IL)-1 beta (IL-1β), alpha (IL-1α), receptor antagonist (IL-1Ra), IL-10 and IL-13 in peri-mini-screw crevicular fluid (PMCF) between unloaded and immediately loaded mini-screws during orthodontic treatment.
Design: Single-centre paired split-mouth controlled trial.
Participants: Patients who required at least two mini-screws as a part of their orthodontic treatment at orthodontic clinic of School of Dentistry of Ribeirão Preto, University of São Paulo (USP) were recruited.

Background: This study aimed to compare palatal versus buccal protraction using plates assisted with a facemask in growing Class III patients.
Methods: Twenty growing Class III patients were randomly allocated into two main groups. In Group 1, a surgical mini-plate was bent into a semicircular shape and adapted to the patient's model to extend from the canine area on one side to the contralateral canine area.

Distalization is a fundamental orthodontic strategy for correcting Class II and Class III malocclusions, particularly in cases where specific dental or skeletal conditions favor its application. Recent technological advances have enabled complex dental movements to be performed using clear aligners, aided by digital planning platforms such as ClinCheck. This retrospective study aimed to evaluate the accuracy of ClinCheck in predicting molar and canine distalization outcomes with the Invisalign system and to identify clinical factors influencing treatment predictability.

Objective: To explore the three-dimensional (3D) displacement patterns of maxillary molar distalization using clear aligners (CA) under four anchorage designs and provide clinical guidelines for optimal traction methods.
Materials And Methods: A 3D finite element model was constructed based on CBCT and digital models from an adult patient requiring maxillary molar distalization. The model included cortical bone, cancellous bone, periodontal ligament, teeth, CA, and mini-screws.
