- Biomechanics of molar rotation with the transpalatal arch: applicability of Burstone's six geometries. [Journal Article]Angle Orthod. 2026 Jul 30. [Online ahead of print]AO
- CONCLUSIONS: The TPA functions as a flexible elastic frame, not a rigid linear beam. Vertical legs significantly dampen the force system, rendering the omega loop mechanically redundant. Notably, compensatory bends, generally used for unilateral rotation activation, are often biomechanically unnecessary in high-vaulted patients, as the system naturally reduces the contralateral moment to zero within the mechanical tolerance of the attachment.

- Training the algorithmically augmented orthodontist: competencies, curriculum design, and implementation challenges. [Journal Article]Angle Orthod. 2026 Jul 29. [Online ahead of print]AO
- CONCLUSIONS: Integrating AI into orthodontic education is increasingly necessary to prepare future clinicians for evolving practice environments. This framework provides a practical foundation for curriculum development and encourages broader discussion to establish shared standards for AI competencies in orthodontics.

- Orthodontic-related posts on Instagram: are they evidence based? [Journal Article]Angle Orthod. 2026 Jul 29. [Online ahead of print]AO
- CONCLUSIONS: This study confirms a lack of evidence-based orthodontic posts on Instagram. The small number of posts that cite scientific literature rely on moderate to low-quality studies. A coordinated effort among clinicians, professional societies, and online platforms is required to improve the credibility and quality of orthodontic information.

- Perception of smile attractiveness with different orthodontic aligner configurations. [Journal Article]Angle Orthod. 2026 Jul 29. [Online ahead of print]AO
- CONCLUSIONS: Orthodontic aligners are generally considered an esthetically acceptable treatment option. Simpler configurations, without accessories or with limited anterior attachments, showed attractiveness comparable to the natural smile, whereas multiple accessories negatively affected smile perception.

- Clinical comparison of different debonding techniques of clear aligner attachments: a single-center, split-mouth randomized clinical trial. [Journal Article]Angle Orthod. 2026 Jul 24. [Online ahead of print]AO
- CONCLUSIONS: Both debonding techniques yielded clinically similar results. The Bur technique resulted in significantly higher pain only in lower posterior segments. Adhesive removal pliers were effective for optimized and conventional attachments, usually leaving less than half of the adhesive.

- Effects of platelet lysate on the rate of orthodontic tooth movement: a single-center, split-mouth, randomized controlled trial. [Journal Article]Angle Orthod. 2026 Jul 24. [Online ahead of print]AO
- CONCLUSIONS: APL did not significantly enhance the rate of canine retraction, and OPG and sRANKL levels showed no consistent changes.

- Comparison of the effects of Hanks Herbst vs twin block following the removal of fixed appliances in Class II correction: a randomized controlled trial. [Journal Article]Angle Orthod. 2026 Jul 21. [Online ahead of print]AO
- CONCLUSIONS: The HH appliance provides efficient short-term overjet correction. However, following comprehensive fixed appliance therapy, skeletal, occlusal, and patient-reported outcomes are comparable between HH and TB. Both clinical effectiveness and patient experience should guide functional appliance selection.

- Biomechanical effects of overcorrection design on extraction space closure with clear aligners: a finite element analysis. [Journal Article]Angle Orthod. 2026 May 27. [Online ahead of print]AO
- CONCLUSIONS: Overcorrection in clear aligner therapy functions biomechanically like V-bends in conventional archwires, counteracting excessive tipping toward the extraction site during extraction space closure. The biomechanical outcome is sensitive to the degree and position of overcorrection, highlighting the need for individualized overcorrection strategies.

- In situ comparison of thermoplastic and thermoset orthodontic elastomeric chains after 30 days of intraoral exposure. [Journal Article]Angle Orthod. 2026 Jul 10. [Online ahead of print]AO
- CONCLUSIONS: After 30 days of intraoral exposure, thermoset elastomeric chains demonstrated superior mechanical stability and force retention compared with thermoplastic chains. Although transparent elastomers were more susceptible to discoloration, esthetic changes remained clinically acceptable. These findings reflect elastomeric behavior under controlled intraoral conditions.

- Comparison of three-dimensional scan and conventional indirect bonding methods for bracket positioning accuracy: an in vitro study. [Journal Article]Angle Orthod. 2026 Jul 10. [Online ahead of print]AO
- CONCLUSIONS: The 3D-printed jig demonstrated greater accuracy in the mandible, while the conventional silicone tray was more accurate in the maxilla. However, the differences were not clinically significant, and both techniques achieved clinically acceptable bracket transfer accuracy.

- Dentoskeletal and soft tissue effects of clear aligner mandibular advancement appliances versus Activator for skeletal Class II malocclusion: a retrospective clinical study. [Journal Article]Angle Orthod. 2026 Jul 10. [Online ahead of print]AO
- CONCLUSIONS: Activator and MA effectively advanced the mandible, retracted upper incisors, reduced overjet, and improved soft tissue profile. MA is more effective in improving upper incisor proclination and facial profile esthetics than the Activator.

- Impact of cone-beam computed tomography image quality on artificial intelligence-driven three-dimensional tooth segmentation and evaluation of external apical root resorption. [Journal Article]Angle Orthod. 2026 Jun 25. [Online ahead of print]AO
- CONCLUSIONS: The method is reproducible and reliable for linear and volumetric external apical root resorption (EARR) measurements using AI-generated STL models. CBCT image quality does not appear to influence volume measurements. Mild EARR was observed between T0 and T1, with no significant differences.
