Do fluorescent agents alter the mechanical strength of orthodontic adhesives? An in vitro and clinical study
ConclusionThe addition of fluorescent elements does not alter the mechanical strength and performance of the orthodontic adhesive and represents a viable alternative for clinical application. (Source: Progress in Orthodontics)

Pain level between clear aligners and fixed appliances: a systematic review
ConclusionsBased on a moderate level of certainty, orthodontic patients treated with Invisalign appear to feel lower levels of pain than those treated with fixed appliances during the first few days of treatment. Thereafter (up to 3 months), differences were not noted. Malocclusion complexity level among included studies was mild. Pain is one of many considerations and predictability and technical outcome are more important, mainly considering that the difference does not seem to occur after the first months of the orthodont ic treatment.

The informative value and design of orthodontic practice websites in The Netherlands
ConclusionsThe websites of orthodontic practices in The Netherlands do not fully comply with CED guidelines on ethical advertising. Readability of the displayed information and website technical performance needs to be further optimized. (Source: Progress in Orthodontics)

Prevalence and severity of apical root resorption during orthodontic treatment with clear aligners and fixed appliances: a cone beam computed tomography study
ConclusionsThe prevalence and severity of ARR measured on CBCT in patients with clear aligners were less than those in patients with fixed appliances. (Source: Progress in Orthodontics)

Alveolar bone remodeling during maxillary incisor intrusion and retraction
ConclusionThe unpredictability of alveolar bone remodeling after upper incisor intrusion and retraction poses significant challenges to treatment planning and patient experience. The study showed that the initial angulation between the incisor and alveolar bone is correlated with the change in angulation after treatment, the initial thickness of the alveolar bone was correlated with the relative change of the alveolar bone thickness (defined as change in thickness after treatment divided by its initial thickness), and the amount of intrusion was correlated with the alveolar bone thickness change at 9-mm apical from the cem...

A comparative assessment of clinical efficiency between premium heat-activated copper nickel-titanium and superelastic nickel-titanium archwires during initial orthodontic alignment in adolescents: a randomized clinical trial
ConclusionThere were no significant between-group differences in alignment efficiency, arch width, and incisor inclination change. There was an increased alignment with 0.014-in. compared with 0.018-in. diameter archwire. (Source: Progress in Orthodontics)

Safe regions of miniscrew implantation for distalization of mandibular dentition with CBCT
ConclusionsThe L6db–L7mb region should be the first choice for miniscrew implantation in the MBS for the distalization of mandibular dentition. (Source: Progress in Orthodontics)

Effects of different nose types on class II treatments for female patients
ConclusionsThe lay people perceived that having a convex-bridged nose was a bigger problem than having a retrognathic profile. Overall, in terms of skeletal and dental orthodontic treatments, nose shape should be considered during the treatment planning process. (Source: Progress in Orthodontics)

Facial esthetic outcome of functional followed by fixed orthodontic treatment of class II division 1 patients
ConclusionsThe perceived facial changes of convex profile patients treated with functional, followed by fixed orthodontic appliances, did not differ from those observed in normal profile patients, when full-face frontal and profile photos were simultaneously assessed. Consequently, professionals should be skeptical regarding the improvement of a patient ’s facial appearance when this treatment option is used. (Source: Progress in Orthodontics)

Usage and comparison of artificial intelligence algorithms for determination of growth and development by cervical vertebrae stages in orthodontics
ConclusionIn our experimental study, kNN and Log.Regr. algorithms had the lowest accuracy values. SVM-RF-Tree and NB algorithms had varying accuracy values. ANN could be the preferred method for determining CVS. (Source: Progress in Orthodontics)

Comparison of a tridimensional cephalometric analysis performed on 3T-MRI compared with CBCT: a pilot study in adults
ConclusionsWithin the main limitation of this pilot study, that is, the small sample, it is possible to state that cephalometric measurements on 3T-MRI seem to possess adequate reliability and repeatability and that they show satisfying agreement with values measured on CBCTs. An MRI examination does not expose patients to ionizing radiation and could provide an alternative to CBCT for three-dimensional cephalometrics in the future. (Source: Progress in Orthodontics)

A novel customized ceramic bracket for esthetic orthodontics: in vitro study
ConclusionsCCB were demonstrated to be an applicable labial orthodontic bracket system with optimized esthetics and biomechanics. We envision that it would be an ideal alternative for patients who pursue esthetic orthodontic treatment but were not likely to take lingual appliances or clear aligners.

Midpalatal suture maturation stage assessment in adolescents and young adults using cone-beam computed tomography
ConclusionsThe possibility to find open midpalatal suture in post-adolescents and young adults is greater than the orthodontists considered years ago. Furthermore, men are more likely to find midpalatal suture opening. These implications might be considered by the orthodontists when maxillary expansion is required. Besides, the ossification of the middle palatal suture is very variable, and therefore, the use of CBCT might be recommended to clarify this possibility. (Source: Progress in Orthodontics)

3D effects of a bone-anchored intra-oral protraction in treating class III growing patient: a pilot study
ConclusionClass III elastics combined with the Alt-RAMEC activation protocol of the hybrid MARME appliance is an effective treatment method for mild/moderate class III malocclusions. A long-term follow-up and comparisons with other treatment modalities are required. (Source: Progress in Orthodontics)
