TL;DR: A summary of the Task Force's findings and recommendations on the suggested role of the specialty of orthodontics in the management of obstructive sleep apnea is presented.

TL;DR: 3D printed and suitably cured Dental LT resin-based clear dental aligners are suggested to be more suitable for patient use as they are geometrically more accurate and presents an opportunity to make processing time savings while ensuring an aligner is mechanically stronger and elastic in comparison with the conventionally produced thermoplastic-based thermoformed clear dental aligneders.

TL;DR: 100-μm layer height 3D-printed models are potentially clinically acceptable for the purposes of evaluation of treatment outcomes, diagnosis and treatment planning, and residency training.

TL;DR: The conventional vacuum‐formed retainer showed the least amount of deviation from the original reference models and the 3D‐printed retainers showed the greatest deviation, however, all 3 methods yielded measurements within 0.5 mm, which has previously been accepted to be clinically sufficient.

TL;DR: There is very low to low evidence for supporting positive associations between root resorption and increased force levels, force continuity, intrusive forces, and treatment duration, and it may be possible for the clinician to reduce the severity of the condition.

TL;DR: Firms between 50 cN and 100 cCN seem optimal for OTM, patient comfort and potentially exhibit fewer side effects, Nevertheless, careful data interpretation is necessary because of the lack of strong evidence.

TL;DR: Factors influencing compliance with removable functional appliance included: self‐motivation, peer and authority influence, quality of life impairment and adaptability, perceived treatment progress, and pragmatic and recall issues.

TL;DR: 3D digital dental models generated by the DM smartphone application in photograph and video modes are accurate enough to be used for clinical applications.

TL;DR: Good‐fit 3D‐printed splints generated from offset dental models can fit better on the teeth than a no‐offset dental model, and could reduce the clinical error in dental use.

TL;DR: Different CBCT exams with equal scanning and patient positioning protocols can result in different 3D PAS readings, and a more careful interpretation of CBCT volumetric data is necessary to achieve adequate conclusions of the clinical outcomes.

TL;DR: There was no difference in either dental or skeletal changes achieved with PT or FT wear of a Twin‐block appliance over 12 months, and less onerous PT wear regimens may be a viable alternative toFT wear of removable functional appliances.

TL;DR: In this article, the authors identify an optimal insertion angle and position for orthodontic mini-implants in the anterior palate using Maxillary cone-beam computed tomographic (CBCT) scans from 30 patients.

TL;DR: In customized lingual orthodontic treatment, power arms located at the distal side of the canines are unfavorable for anterior teeth torque control and intercanine width control.

TL;DR: More convex skeletal and soft-tissue profiles, more prominent noses with higher tips, subnasales anterior to the upper lip, more protruded upper lips, less prominent lower lips, smaller interlabial gaps, and more protruding chins might improve profile esthetics.

TL;DR: An interactive power toothbrush generated increased brushing times and significantly greater plaque removal versus a manual brush and subject‐reported motivation was significantly increased in the interactive power brush group at week 6 versus screening.

TL;DR: Although no statistically significant differences were found among the groups, the mean VAS scores for the mechanical vibration group were consistently lower than those of the control and low-level laser therapy groups at all measured time points.

TL;DR: RME in the mixed dentition with the appliance anchored to deciduous teeth did not reduce the buccal bone plate thickness of the maxillary permanent first molars, except for the mesial roots on both sides.

TL;DR: The modified PET‐G, with a higher modulus of elasticity and greater abrasion resistance, showed a more stable and lower force change than did the conventional PET‐g, which was a promising and applicable material with advantages for both orthodontists and patients.

TL;DR: The convenience of maintaining oral hygiene rather than changes in the oral microbiome may be the underlying reason for the performance of the Invisalign system on oral health.

TL;DR: The application of platelet‐rich plasma was not beneficial as an adjunct to orthodontic treatment and there was no statistical significance among the groups at day 14.

TL;DR: 3-Dimensional changes of the zygomaticomaxillary complex after MARME showed expansion in a pyramidal shape from the coronal view, downward and forward displacement from the sagittal view, and parallel palatal expansion from the axial view.

TL;DR: Fixed and removable orthodontic retainers do not differ in salivary S mutans and L casei levels and periodontal status with all retainers, regardless of whether they are fixed or removable.

TL;DR: This study found relatively high compliance in the short-term retention phase for both appliances in a 3-month period after active orthodontic treatment through the use of the thermosensitive microsensor TheraMon.

TL;DR: The complexity of orthodontic traction of impacted maxillary canines is not a risk factor for greater RR of maxillary incisors close to the impaction area, and multiple linear regression indicated no significant influence of orthdontic treatment complexity on RR.

TL;DR: The present findings indicate that the stress manifested at the apical third of the pulp is smaller than that at NVB, andRotational movements induce the highest stress and translational forces develop the lowest stress related to the physiologic capillary blood pressure.

TL;DR: Split-type 3D printing of presurgical nasoalveolar molding helped to reduce the cleft gap, improve the arch form, approximate lip segments, and distinctly improve the morphology of the nose by correcting the flattened nasal wings.

TL;DR: An interesting effect of PDI using modified hematoporphiryn IX was found, suggesting a promising use against dental caries and white spot lesions and synthesis of new and efficient photosensitizers shows potential for clinical research.

TL;DR: Based on the present review, combined orthodontic-surgical treatment could be an effective choice to improve OHRQoL for patients affected with severe dentofacial deformities.

TL;DR: It may be possible to perform maxillary total arch distalization in adolescents with unerupted third molars without a germectomy, at least in the short term, with an insignificant difference in the posttreatment volume of maxillary tuberosity.

TL;DR: The quality of reporting of abstracts of orthodontic systematic reviews and meta-analyses increased after the introduction of PRISMA-A, and poor adherence revealed that there is still need for improvement in the quality of abstract reporting.
