The effect of space arrangement between anterior teeth on their retraction with clear aligners in first premolar extraction treatment: a finite element study
ConclusionThese analyses indicate that spaces between the anterior dentition during anterior retraction are beneficial for decreasing the tendency for extrusion of the anterior dentition and require provision of anchorage. Appropriate spaces can be designed to lest the lingual tipping and extrusion effect of the anterior teeth while simultaneously reducing the maximum stresses on PDLs.

Prevalence of adenoid hypertrophy among 12-year-old children and its association with craniofacial characteristics: a cross-sectional study
ConclusionsThe prevalence of children with AH ranged from 13.9 to 19.0% based on LCR. Greater antero-posterior maxillo –mandibular discrepancy and mandibular retrusion were independently associated with higher likelihood of having AH. (Source: Progress in Orthodontics)

Extracellular vesicles derived from M1 macrophages enhance rat midpalatal suture expansion by promoting initial bone turnover and inflammation
ConclusionsM1 macrophage-derived small extracellular vesicles have a positive effect in MPS expansion and increase p65 protein content and RANKL expression, thus promoting bone turnover. This study may contribute to the clinical application of small extracellular vesicles in the expansion of the palatal suture. (Source: Progress in Orthodontics)

Ridge mini-implants, a versatile biomechanical anchorage device whose success is significantly enhanced by splinting: a clinical report
ConclusionRidge mini-implants offer significant biomechanical versatility in patients with partially edentulous ridges needing complex pre-prosthetic orthodontic movements. The presence of splinting and the length of the used mini-implants are factors that might affect the clinical success of the alveolar ridge mini-implants. (Source: Progress in Orthodontics)

The relationship between different levels of facial attractiveness and malocclusion perception: an eye tracking and survey study
ConclusionWhile a worsening of the ideal smile had a smaller impact on aesthetic perceptions in an individual with low facial attractiveness, it had a significant negative impact on a person with high facial attractiveness. Anterior crowding and diastema had a more negative impact on facial attractiveness than low or high smile lines. (Source: Progress in Orthodontics)

Aging changes in maxillary anterior teeth in untreated individuals: an observational longitudinal study
ConclusionsFrom adolescence to late adulthood, untreated individuals with normal occlusions demonstrated changes in the maxillary anterior teeth that may impair the smile esthetics and attractiveness. (Source: Progress in Orthodontics)

Does different vertical position of maxillary central incisors in women with different facial vertical height affect smile esthetics perception?
ConclusionsThe facial vertical height significantly affected the perception of smile esthetics. Keeping the distance between the central and lateral incisors longer than 1  mm in individuals with increased facial height may be important in terms of increasing patient satisfaction in terms of clinical aesthetics. On the contrary, keeping the distance between the central and lateral incisors shorter than 1 mm may create a more esthetically acceptable result in individ uals with short facial height.

3D occlusal changes of upper first molars after rapid maxillary expansion on permanent versus deciduous teeth: a retrospective multicenter CBCT study
ConclusionsRME is effective in treating maxillary transverse hypoplasia; RME anchored too deciduous teeth spontaneously reduces buccal inclination and increases distorotation of maxillary first permanent molars, whereas anchorage to permanent molars is associated with increased buccal inclination, albeit with little clinical significance.

Impact of molar teeth distalization by clear aligners on temporomandibular joint: a three-dimensional study
ConclusionTreatment by sequential upper molars distalization with clear aligners does not lead to significant TMJ parameters changes in condyle and fossa spaces, dimensions, and positions. (Source: Progress in Orthodontics)

Forces and moments generated by 3D direct printed clear aligners of varying labial and lingual thicknesses during lingual movement of maxillary central incisor: an in vitro study
ConclusionsTargeted increases in thickness of direct 3D-printed aligners change the magnitude of forces and moments generated, albeit in complex patterns that are difficult to predict. The ability to vary labiolingual thicknesses of DPAs is promising to optimize the prescribed orthodontic movements while minimizing unwanted tooth movements, thereby increasing the predictability of tooth movements.

“Dear Doctor, greetings of the day!”: A 1-year observational study of presumed predatory journal invitations
Conclusions Nearly 8  out of 10 unsolicited e-mail invitations sent to orthodontists for scholarly contribution may be related to journals suspicious for publishing malpractices and suboptimal standards. Excessive flattering language, grammatical errors, broad range of submissions, and incomplete journal contact inform ation were commonly encountered findings. Researchers in orthodontics should be alert to the unethical policies of illegitimate journals and their harmful consequences on the scientific literature. (Source: Progress in Orthodontics)

Dentofacial effects of miniscrew-anchored maxillary protraction on prepubertal children with maxillary deficiency: a randomized controlled trial

Three-dimensional analysis of miniscrew position changes during bone-borne expansion in young and late adolescent patients
ConclusionsWhile acting as bone anchor units, miniscrews do not remain in the same position during bone-borne expansion. The amount of displacement was related to peri-sutural total bone height and cortical thickness, especially in the anterior area of the naso-frontal maxillary complex.
