Special Issue Information

Dear Colleagues,

In recent years, the field of orthodontics and dentofacial orthopedics has witnessed substantial growth, with significant technological innovations and scientific discoveries transforming clinical practice. Digital technologies, advanced biomaterials, and interdisciplinary approaches have revolutionized diagnosis, treatment planning, and therapeutic outcomes in managing various dentofacial anomalies. Staying at the forefront of these developments is crucial for both researchers and clinicians to optimize patient care and contribute to the advancement of this field.

We would like to invite you to contribute to this Special Issue on "Advances in Orthodontics and Dentofacial Orthopedics”, which aims to compile cutting-edge research and comprehensive reviews that highlight recent innovations and future directions in orthodontic diagnosis, treatment modalities, and clinical outcomes.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Digital technologies in orthodontic diagnosis and treatment planning;
  • Clear aligner systems and their biomechanical considerations;
  • Temporary anchorage devices and skeletal anchorage systems;
  • 3D imaging and analysis in orthodontics;
  • Artificial intelligence applications in orthodontic practice;
  • Growth modification techniques and dentofacial orthopedics;
  • Accelerated tooth movement methodologies;
  • The management of complex dentofacial deformities;
  • Interdisciplinary approaches in orthodontic treatment;
  • Biomarkers and personalized orthodontic treatments.

We look forward to receiving your contributions.

This study evaluated the effects of different clear aligner (CA) designs on forces and moments during maxillary second molar distalization. Four designs were tested: attachment only (group 1), neither attachment nor enhanced structure (group 2), a combination of attachment and enhanced structure (group 3), and enhanced structure only (group 4). CAs were fabricated from thermoformed polyethylene terephthalate glycol with 30 CAs per group. Forces and moments were measured using a multi-axis transducer as the molars were distally displaced by 0.25 mm. All groups experienced buccodistal and intrusive forces. Group 3 showed the highest distalizing force (Fy = 2.51 ± 0.37 N) and intrusive force (Fz = −2.04 ± 0.48 N) and also the largest rotational moment (Mz = 3.89 ± 0.71 Nmm). Groups 3 and 4 (with enhanced structures) demonstrated significant intrusive forces (p < 0.05). Most groups exhibited mesiodistal angulation, lingual inclination, and distal rotational moments. Group 2 had the lowest moment-to-force ratio (Mx/Fy = 3.27 ± 0.44 mm), indicating inefficient bodily movement. Group 3 demonstrated significantly greater moments across all axes compared to other groups. The results indicate that designs incorporating enhanced structures with attachments increase CA stiffness and applied forces/moments, enhancing distalization efficiency while minimizing vertical side effects. This suggests that, clinically, reinforced CAs can serve as a simple yet effective modification to existing protocols in Class II orthodontic cases, enabling more efficient molar distalization without requiring complete appliance redesign or additional fabrication and allowing easy adaptation to individual treatment needs.
