Evaluation of the use of a clinical practice guideline for external apical root resorption among orthodontists
ConclusionsThis questionnaire demonstrated that, 3 years after introduction of the guideline, orthodontists improved their self-reported clinical practices to a more standardised management of root resorption. None of the demographic predictors had a significant effect on the results. (Source: Progress in Orthodontics)

Digital setup accuracy for moderate crowding correction with fixed orthodontic appliances: a prospective study
ConclusionsThe accuracy of semi-automatic prediction of the labial fixed appliance treatment outcome in Class I cases with moderate crowding is not yet sufficient. While average measures showed deviations less than 1 mm, examination of individual color-coded distance maps revealed significant disparities between the simulated and the actual results.

Factors influencing root resorption in retained mandibular second deciduous molars with congenital absence of second premolars: a cross-sectional study
ConclusionsOur findings suggest that skeletal morphology, oral morphological patterns, and history contribute to root resorption in retained mandibular second deciduous teeth with congenital absence of subsequent permanent teeth. (Source: Progress in Orthodontics)

“Examining the link between tooth agenesis and papillary thyroid cancer: is there a risk factor?” Observational study
ConclusionOur study suggests a possible link between odontogenesis and PTC. The absence of permanent teeth may increase the likelihood of PTC in women. Leveraging the age-7 orthopantomogram to identify women at high risk for PTC within a critical early detection window could significantly improve oral health outcomes and PTC prognosis through proactive interventions.

Comparison of 3D-printed and laboratory-fabricated Hyrax on stress distribution and displacement of the maxillary complex: a 3D finite element study
ConclusionThe F-Hyrax exerts more stress and displacement on the maxilla than both the T-Hyrax and H-Hyrax, where the weak link appears to be the solder joint. (Source: Progress in Orthodontics)

Biomechanical analysis of total arch maxillary distalization using infrazygomatic crest miniscrews: a finite element analysis study
ConclusionThe maxillary incisors and canines have different immediate movement tendencies according to the height of the anterior point of the en-masse distalization force application. Based on the PA height increase, a change from lingual to buccal tipping and less extrusion tendency was observed for the incisors, while the lingual tipping and extrusion trend for canines increased.

The association between self-esteem and aesthetic component of smile among adolescents
ConclusionThe self-esteem in adolescence is influenced the most by gender, but the orthodontic treatment and better smile aesthetics might also contribute. (Source: Progress in Orthodontics)

Skeletal stability of inter-molar mandibular distraction osteogenesis in growing patients
ConclusionsIMDO was highly stable within a follow-up period of 2.3  ± 0.9 years; however, growth appears to have been inhibited. (Source: Progress in Orthodontics)

Surface wear of attachments in patients during clear aligner therapy: a prospective clinical study
ConclusionsThe volume of attachment wear increased gradually with treatment time. Sex, attachment type, and initial attachment volume were risk factors for the volume of attachment wear. The deepest wear regions of 3-mm rectangular attachments were at the corners of gingival edges, while the deepest wear regions of optimized attachments were at surface ridges. Four months after treatment, optimized root control attachments showed more relative wear than 3-mm rectangular attachments. (Source: Progress in Orthodontics)

The effect of micro-osteoperforations on the rate of maxillary incisors' retraction in orthodontic space closure: a randomized controlled clinical trial
ConclusionsMOPs did not accelerate the retraction of the maxillary incisors, nor were they associated with greater incisor inclination or root resorption.Trial registration ClinicalTrials.gov NCT03089996.

The effect of vertical skeletal proportions, skeletal maturation, and age on midpalatal suture maturation: a CBCT-based study
ConclusionsBased on this cross-sectional analysis, midpalatal sutural maturation classification is associated with chronological age and occurs later in males. Neither CVM staging nor variation in vertical skeletal proportions were useful predictors of midpalatal maturation stage. (Source: Progress in Orthodontics)

Curve of Spee modification in different vertical skeletal patterns after clear aligner therapy: a 3D set-up retrospective study
ConclusionTreatment with aligners did not lead to a clinically significant change in COS depth. However, when dividing the sample into groups based on craniofacial divergence, COS depth change differed significantly between the three groups. (Source: Progress in Orthodontics)

The effect of enhanced structure in the posterior segment of clear aligners during anterior retraction: a three-dimensional finite element and experimental model analysis
ConclusionsEnhanced structure allowed force distribution more in accordance with optimal principles of biomechanics during the extraction space closure while permitting less mesial tipping and anchorage loss of posterior teeth and better retraction of anterior teeth. Thus, enhanced structure alleviated the roller coaster effect associated with extraction cases and offered a new possibility for anchorage reinforcement in clear aligner therapy.

Mechanical force increases tooth movement and promotes remodeling of alveolar bone defects augmented with bovine bone mineral
ConclusionThis study explored the mechanisms of mechanical force-induced alveolar bone remodeling with bovine bone mineral grafts during OTM. The results might provide molecular insights into the related clinical problems of whether we can move teeth into the grafted materials; and how these materials become biologically remodeled and degraded under mechanical force.

Comparison of the effects on facial soft tissues produced by rapid and slow maxillary expansion using stereophotogrammetry: a randomized clinical trial
ConclusionsRME produced significant facial soft tissue changes when compared to SME. RME induced greater increases in both nasal and intercanthal widths (1.3  mm and 0.7 mm, respectively). These findings, though statistically significant, probably are not clinically relevant.Trial registration ISRCTN, ISRCTN18263886.
