Special Issue Information

Dear Colleagues,

In this era of great technological advancements in modern orthodontics, the introduction of new materials and associated techniques has the potential to advance the current limits of orthodontic treatments. However, the introduction of such materials and techniques is seldom accompanied by real experimentation. Due to the laws of the market, new products are often introduced without large-scale experimentation on their effects over time. From this point of view, there is a need to fill the research gap produced by corporate pressure by performing rigorous testing of the effects of these modern technologies over time in both adult and adolescent patients. This Special Issue aims to critically appraise the innovative technologies used in daily orthodontic practice to define their benefits and limitations.

In this Special Issue, original research articles, short communications, and reviews are welcome. Research areas may include, but are not limited to, the following: digital orthodontics, miniscrew-supported treatment, the application of cone beam computed tomography in orthodontics, and clinical treatments in adult orthodontic patients.

I look forward to receiving your contributions.

Dr. Gabriele Di Carlo
Guest Editor

Background: This in vitro study aimed to evaluate the shear bond strength (SBS) of orthodontic brackets bonded using different techniques and assess whether bovine enamel demonstrates comparable behavior to human enamel in SBS testing. Methods: A total of 80 human premolars and 80 bovine mandibular incisors were randomly assigned to four bonding protocol groups according to the adhesive procedure applied: (1) adhesive only; (2) etching + adhesive; (3) etching + primer + adhesive; and (4) etching + primer + bracket base primer + adhesive. Shear bond strength (SBS) testing was performed using a universal testing machine at a crosshead speed of 1 mm/min. Data were analyzed using two-way ANOVA and Tukey’s post hoc tests (p < 0.05). Results: Both bonding protocol and enamel substrate significantly affected SBS values (p < 0.001), whereas the interaction between these factors was not statistically significant (p = 0.061). SBS values generally increased as the bonding protocol became more complex. The adhesive-only groups demonstrated significantly lower SBS values than the other bonding protocols in both human and bovine enamel. Human enamel demonstrated significantly higher SBS values than bovine enamel overall (p < 0.001). Conclusions: Within the limitations of this in vitro study, increasing bonding protocol complexity generally resulted in higher SBS values in both human and bovine enamel. Although bovine enamel demonstrated similar overall trends across bonding procedures, significant differences between human and bovine enamel were observed. Therefore, bovine enamel should not be considered directly interchangeable with human enamel for absolute SBS measurements. Further in vivo and clinical studies are required before simplified bonding protocols can be recommended for clinical application. Full article

This study evaluated the biomechanically optimal insertion angle for miniscrew-assisted anterior intrusion by analyzing stress in the periodontal ligament (PDL) and alveolar bone. A three-dimensional finite element model from cone-beam computed tomography (CBCT) data, comprising maxillary bone, anterior dentition, and a bonded orthodontic appliance, and segmented 0.019 × 0.025-inch stainless-steel archwire were used. Titanium miniscrews (1.4 × 6 mm) were placed at 5 mm from the alveolar crest between the lateral incisor and canine. Four insertion angulations relative to the occlusal plane (30°, 60°, 90°, and 120°) were simulated under a 90 g intrusive force. Results demonstrated that while all configurations achieved intrusion with minor labial tipping and maintained miniscrew stability, stress localization was highly angle-dependent: the 90° insertion generated the highest central incisor PDL tensile stress and maximum cortical bone Von Mises stress; the 120° insertion yielded peak canine PDL Von Mises stress and maximum root displacement; and the 60° insertion localized peak stresses within the cancellous bone and the bone–implant interface. Miniscrews remained stable in all scenarios. While all tested miniscrew angulations provided stable anchorage for upper anterior teeth intrusion, the selection of insertion angle critically influenced stress patterns within the supporting tissues.
