Special Issue Information

Dear Colleagues,

One of the main constraints of orthodontic treatment is its long duration. The number of scientific publications on the topic of accelerating orthodontic treatment in order to reduce treatment time (by stimulating bone remodeling and tooth movement) has increased in recent years.

Several procedures are used to achieve this, such as the following:

  • Surgical methods (corticotomy, piezocision, microsteoperforation);
  • Physical and mechanical stimulation methods (laser, vibration, and photobiostimulation);
  • Local or systemic drugs (vitamin D, local prostaglandin injections, and interleukin).

The above-mentioned methods have many advantages, such as the following:

  • Reduction in treatment time (30–60%);
  • Reduced risk of root resorption and caries;
  • Improved patient compliance and satisfaction (less discomfort compared to traditional methods).

Research shows mixed results—strongest evidence exists for surgical methods; moderate evidence exists for vibration devices; and limited evidence exists for photobiostimulation.

The future directions of these methods are gene therapy for bone remodelling, personalized acceleration protocols based on biomarkers; and smart materials with programmed tooth movement.

Accelerated orthodontics represents a significant shift in orthodontic practice, offering patients faster results with comparable stability to traditional methods when correctly employed. However, long-term prospective studies should be carried out to assess the stability of these results and long-term effects on the periodontium with good periodontal tolerance and teeth vitality.

Background/Objectives: Pediatric obstructive sleep apnea (OSA), particularly when accompanied by mandibular retrognathia, presents as a complex, multifactorial condition. Dentofacial orthopedic treatment (DOT) has gained increasing clinical attention; however, high-level evidence specifically demonstrating its efficacy in pediatric OSA remains scarce. This study aimed to evaluate the efficacy of DOT and AT in managing mild to moderate OSA in children with mandibular retrognathia. Methods: This open-label, randomized controlled clinical trial recruited 93 children aged 7–10 years with mild to moderate OSA (an AHI of 1–10 events per hour) and mandibular retrognathia (ANB angle ≥ 4.5°). Participants were randomly allocated to four groups: pharmacotherapy, DOT (combined maxillary expansion and mandibular advancement appliance), AT (adenotonsillectomy under general anesthesia), and AT & DOT groups. The primary outcome was the change in apnea–hypopnea index (AHI) from baseline to 7 months post-treatment. Secondary outcomes included assessments of dentofacial development and volumetric changes in the upper airway. Results: Because of the high dropout/loss-to-follow-up rates in the pharmacotherapy and AT plus DOT groups, the final analysis was restricted to the DOT and AT groups, in which the overall dropout/loss-to-follow-up rate was 19.6%. Among the 43 participants allocated to the DOT (8 girls and 15 boys) and AT groups (8 girls and 12 boys), 36 completed the follow-up, the median baseline AHI was 3.7 events/h [IQR, 1.9–4.4]. Per protocol analysis revealed a mean reduction in AHI of 1.6 events/h in the DOT group and 1.3 events/h in the AT group, with no significant difference between the groups (−0.43 [95% CI, −1.48 to 0.61], p = 0.40). DOT significantly promoted sagittal mandibular growth without inducing a vertical clockwise rotation tendency, whereas AT had no significant effect on dentofacial development. Total upper airway volume increased significantly in both groups, with the increase concentrated in different regions of the upper airway depending on the group. Conclusions: In children with mild to moderate OSA and mandibular retrognathia, DOT demonstrated comparable efficacy to AT, which may be attributable to favorable anatomical remodeling of the upper airway.

Background/Objectives: Acceleration of orthodontic tooth movement remains a major challenge in clinical orthodontics. Evidence suggests that increased local blood flow around the alveolar bone is key to bone remodeling and potentially reflects early biological responses associated with accelerated orthodontics. This study aimed to investigate the effects of non-invasive physical stimuli on gingival microcirculation. Methods: Eight healthy adult male volunteers were included in the analysis. Gingival blood flow was assessed using laser Doppler flowmetry under the following conditions: no-stimulation condition (None) and four types of stimuli: thermal stimulation (THM), electric field stimulation (ELF), vibration stimulation (VIB), and far-infrared stimulation (FIR). Gingival blood flow was recorded before and after each stimulation, and the rate of change was calculated. Statistical analysis was performed using a linear mixed-effects model with Type III ANOVA (Satterthwaite approximation), followed by Dunnett-adjusted comparisons. Results: A statistically significant difference was observed between stimulation conditions (p = 0.0087). VIB significantly increased gingival blood flow compared with the no-stimulation condition (p = 0.0041), whereas ELF showed a trend toward increased blood flow (p = 0.0936); THM and FIR showed no statistically significant effects. Conclusions: The findings of this study suggest that non-invasive physical stimuli, particularly vibration stimulation, can enhance gingival microcirculation. Although tooth movement was not directly evaluated, the observed hemodynamic changes may represent short-term physiological responses to non-invasive physical stimulation. Full article

Objectives: This study aimed to analyze the three-dimensional displacement of maxillary first molars using a finite element model with two headgear configurations, namely cervical and horizontal pull headgears, as well as pendulum, infrazygomatic miniscrews, Bollard miniplates, Advanced Molar Distalization Appliance (AMDA), and Beneslider. The goal was to clarify how variations in anchorage design and force direction influence molar movement across the sagittal, vertical, and transverse planes. Methods: A three-dimensional finite element model of the maxillary dentition and supporting structures was constructed using reference anatomical data and standardized material properties. Each appliance was virtually simulated under its clinically recommended force magnitude and direction to ensure realistic biomechanical conditions. The orientation of each force vector relative to the molar’s center of resistance (CR) was analyzed, and resulting tooth displacements were quantified along the sagittal (Z), vertical (Y), and transverse (X) axes using 49-node reference paths connecting key anatomical landmarks. Results: Appliances applying forces through or above the molar CR, such as the AMDA, infrazygomatic miniscrews, and Bollard miniplates, produced nearly bodily distalization with minimal tipping (<0.6° (range 0.3–0.6°)) and slight intrusion (−0.12 to −0.18 mm). Conversely, systems delivering forces below the CR, such as the cervical headgear and pendulum, resulted in greater crown tipping and extrusion. The Beneslider exhibited an intermediate displacement pattern with moderate vertical control. Conclusions: Force vector height and direction relative to the molar CR critically determine 3D displacement behavior. Skeletal anchorage and adjustable systems, particularly the AMDA, demonstrated the most controlled distalization pattern with minimal tipping, whereas conventional tooth-borne designs induced more tipping and extrusion.

Background: Periodontally accelerated osteogenic orthodontics (PAOO) is a surgical procedure to accelerate orthodontic tooth movement and minimize periodontal complications. This study surveyed U.S. periodontists to assess various aspects of the procedure as regards prevalence, training, and execution. Methods: The authors developed a unique questionnaire, the first national study of this type, housed on the Qualtrics® survey platform, to analyze trends in PAOO training and use. Unique recruitment emails were sent to 3154 members of the American Academy of Periodontology. 449 U.S. periodontists/3154 surveyed (14.2%) responded to this web-based, anonymized survey. IBM statistical software (SPSS V28) was used for data analysis. Results: Among respondents, PAOO training was received during residency (32.7%) and by continuing education (CE) (50.8%), with higher CE (57.3%) by those who did not receive PAOO residency training (p < 0.001). 38.5% of periodontists perform PAOO, and those most likely to perform PAOO had both PAOO residency training and CE, with 78.5% performing 1–5 cases/year. Most (87.7%) received 1–2 PAOO referrals/year from orthodontists or general dentists. Differences in techniques and materials were the type of bone graft or membrane used, the position of corticotomies, and the timing of orthodontic movement. The primary PAOO goal was “rapid tooth movement” (41.1%) and to “increase the alveolar housing” (37.2%). The secondary (38%) and tertiary (37.2%) ranked goals were “augment dehiscence or fenestration”, with the “prevention of apical root resorption” ranked as their quaternary goal. Conclusions: The results of this survey provide data on the trends, training, and use of PAOO among U.S. periodontists. This information may aid in developing residency curriculum and performing PAOO research. Full article

Background/Objectives: Clinical and scientific professionalization in orthodontics requires a comprehensive understanding of the biomechanical principles governing force generation and distribution produced by orthodontic appliances, beyond purely esthetic considerations. In this context, finite element analysis (FEA) has emerged as a fundamental computational tool for the detailed evaluation of the biomechanical behavior of the dentoalveolar system. The aim of this study was to map and synthesize the available scientific evidence on the application of FEA in the assessment of force distribution, tooth movement, and the mechanical response of periodontal tissues during orthodontic treatment. Methods: Original studies published between 2020 and 2025 that relied exclusively on computational simulations using FEA were included. Eligible studies addressed orthodontic biomechanics, including tooth movement, appliance–tooth–periodontium interactions, or the mechanical evaluation of orthodontic attachments. Clinical studies, narrative reviews, and articles without finite element modeling were excluded. A systematic literature search was conducted in the PubMed and ScienceDirect databases to answer the following question: Which FEA methodologies have been used to evaluate the biomechanical behavior of orthodontic appliances? Results: Data were categorized according to key biomechanical variables. The findings indicate an increasing use of FEA as a supportive tool in orthodontic research. However, significant limitations were identified, including lack of methodological standardization, limited model validation, and insufficient correlation between computational outcomes and clinical evidence. Conclusions: Currently, FEA in orthodontics is used predominantly for descriptive purposes, particularly for visualizing stress and strain distributions. Greater standardization and validation are required to enhance its translational applicability in clinical relevance. Full article
