“…We also found that 18.6% of children aged 9-12 required orthodontic treatment with regard to the IOTN DHC. This result is similar to the figure of 18.9% noted for a sample of 8-12-year-olds in the Lesser Poland region [27]; 15.4% in a sample of 9-year-old Spanish children in Valencia [14]; 21.3% in a sample of 9-12-year-olds in France [16]; and 21.8% along with 20.9% in the case of a group of 12-year-olds in Spain [14,17,33].…”

ABSTRAKTWstęp: Celem pracy była ocena ortodontycznej potrzeby leczenia w populacji dzieci w Szczecinie oraz określenie możliwych czynników związanych z tą potrzebą.Materiały i metody: Badaniem objęto 532 dzieci nieleczonych ortodontycznie, podzielonych na dwie grupy: 279 6–8-latków i 253 9–12-latków. Ortodontyczną potrzebę leczenia oceniono za pomocą komponenty zdrowotnej (DHC) i komponenty estetycznej (AC) wskaźnika ortodontycznej potrzeby leczniczej. Wyniki poddano analizie za pomocą testu χ2. Analizę wieloczynnikowej regresji logistycznej przeprowadzono w celu ustalenia związku między potrzebą leczenia a zmiennymi niezależnymi.Wyniki: Pomiędzy grupami 6–8-latków i 9–12-latków zaobserwowano istotne statystycznie różnice na podstawie dwóch komponent wskaźnika (DHC ≥ 4 i/lub AC ≥ 8) w ocenie wyraźnej potrzeby leczenia (odpowiednio 14% i 20,6%; p = 0,044). Czynniki takie jak nieprawidłowości zębowe, II klasa Angle’a, zwiększony nagryz poziomy, zgryz krzyżowy, a także przemieszczenie punktów kontaktu były istotnie statystycznie związane z wyraźną potrzebą leczenia (DHC stopień 4 i 5).Wnioski: W badanej populacji ortodontyczna potrzeba leczenia była zbliżona lub mniejsza w porównaniu z innymi populacjami europejskimi. Większa potrzeba leczenia zaobserwowana w grupie 9–12-latków podkreśla znaczenie wczesnej diagnozy wad zgryzu oraz konieczności zgłaszania się pacjentów do leczenia we właściwym czasie.

“…A transversal study, both descriptive and analytical, was set up in the context of the 2018 Oral Health Study in the Spanish region known as Comunidad Valenciana. The sample size was established according to the prevalence of malocclusion in the 2010 study; the rates were: 20.9% at the age of 12 and 12.7% at the age of 15 16 , with a 95% confidence level and a precision level of 4%, resulting in a sufficiently large sample size of 687 patients to carry out the study.…”

to study the association between orthodontic treatment need and the psychosocial impact of dental aesthetics in a sample of adolescents, as well as other associated factors. A transversal study was conducted on 1,158 adolescents (12-16 years old) examined at the schools selected for the 2018 epidemiological study on oral health in the Comunidad Valenciana (Spain). The need for orthodontic treatment was determined by DAi and iotn. the psychosocial impact was established by the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ). Other variables considered were sex, social class, DMFT index and Body-Mass Index, and having previously worn or presently wearing an orthodontic device. A lineal regression statistical technique was applied to study the significant associations with the scoring obtained in PIDAQ. The PIDAQ scores revealed a significant and positive lineal relationship with regard to need for orthodontic treatment: DAI (ẞ = 0.20) and IOTN-DHC (ẞ = 4.87), in women (ẞ = 2.66) and a negative one for having previously worn an orthodontic device (ẞ = − 5.74). The rest of the variables had no statistical significance (p > 0.05). The psychosocial impact of dental aesthetics in adolescents is associated with the presence of malocclusion and the female sex, while the condition of having previously worn an orthodontic device reduces the psychosocial impact.

“…Regarding the malocclusion in general, it is thought that the need for orthodontic treatment among teenagers aged from 12–15 years is around 20% [ 3 ], among adults aged 35–44 years it is 31.3% according to the Dental Aesthetic Index (DAI), but 19.2% according to the Index of Orthodontic Treatment Need (IOTN), and 21% according to patients’ subjective perception [ 4 ].…”

Arch expansion with the Invisalign system: Efficacy and predictability

et al. 2020

Background In adult patients, treatment of skeletal crossbite requires combined treatment by fixed or removable appliances and orthognathic surgery. In cases of dentoalveolar crossbite, expansion can be achieved with fixed multibrackets and removable transparent aligners. Various researchers have already assessed the Invisalign system’s predictability for arch expansion. However, most of this research was conducted using older appliances, making it necessary to assess the characteristics of the updated system SmartTrack. Material and methods A sample of 114 patients with transverse malocclusion were treated with SmartTrack. The predictability of the system’s software (Clincheck) was assessed by comparing planned measurements (width of canines, premolars and molars rotations and inclinations) with the real measurements achieved at the end of the first treatment phase. Measurements were imported to Clincheck software to create three data sets; T1: initial measurements at start of treatment; T2: Clincheck predicted measurements at end of first treatment phase; T3: measurements taken at start of the second treatment phase. Results Widths underwent significant advances as a result of treatment. For all widths, virtual planning obtained prognoses of greater expansion than actually achieved: a mean of 0.63 mm more expansion at the canine level (p<0.001), 0.77 mm at first premolar (p<0.001), 0.81 at second premolar (p<0.001), 0.69 mm at first molar (p<0.001), and 0.25 mm at second molar (p = 0.183). All the treatment plan’s estimations, with the exception of the second molar, were significantly higher than the actual outcomes. Conclusions Aligners are an effective tool for producing arch expansion, being more effective in premolar area and less effective in canine and second molar area. Predictability was reasonable for expansion movement. Overcorrection should be considered at the virtual planning stage in order to obtain the expected outcomes.
