“…In young patients with an anterior open bite, resolution of existing digit habits should be the first line of action. In the absence of a digit habit, around three quarters of open bites will spontaneously resolve prior to adolescence . Therefore, in many cases of open bite, it is prudent to defer active treatment until a period of observation has been undertaken.…”

Malocclusion represents the clinically observable endpoint of numerous genetic and environmental influences. Oral Myofunctional Therapy (OMT) aims to treat malocclusions by improving the oral environment through re-education of musculature and respiratory patterns. Although the concept of OMT has existed since the early part of the 20th Century, many of its purported benefits for the treatment of malocclusion remain undemonstrated in the scientific literature. However, a more recent application of OMT for the treatment of Obstructive Sleep Apnoea (OSA) suggests some benefits, although more research is needed to clarify this effect. Prefabricated functional appliances (PFAs) are sometimes advocated as part of myofunctional training programs. In the past decade, controlled clinical investigations have demonstrated that PFAs can improve Class II Division 1 malocclusions in compliant patients. Compared with traditional functional appliances, PFAs might be more cost effective; however, this must be balanced against compliance problems and evidence suggesting that other types of functional appliances might give better treatment results in a comparable time frame.Abbreviations and acronyms: OMT = Oral Myofunctional Therapy; PFA = prefabricated functional appliance; OSA = Obstructive Sleep Apnoea; AHI = apnoea hypopnoea index; RCT = randomised controlled trial.

“…34 In contrast, Phelan et al showed that there was no change in cranial base angle measured as SNBa. 30 This was also supported by Thordarson et al, who showed no difference in cranial base flexure from age 6 to 16 years. 31 In a longitudinal study by Wilhelm et al, there was no difference reported in cranial base angle between different facial classifications, specifically Class I and Class II.…”

“…Bjork reported that the cranial base angle gradually bent throughout childhood up to about 10 years, at which point the cranial base reached its final shape and the cranial base angle remained relatively stable. 2,30,32 Conversely, Bishara, 22 Knott, 36 and Lewis and Roche 26 reported a slight decrease with age during adulthood.…”

Objective: To provide a synthesis of the published studies evaluating the natural growth and development of the human posterior cranial base (S-Ba). Materials and Methods: The search was performed on MEDLINE, Embase, PubMed, and all EBM Reviews electronic databases. In addition, reference lists of the included studies were handsearched. Articles were included if they analyzed posterior cranial-base growth in humans specifically. Study selection, data extraction, and risk of bias assessment were completed in duplicate. A meta-analysis was not justified. Results: Finally, 23 published studies were selected: 5 cross-sectional and 18 cohort studies. Articles were published between 1955 and 2015, and all were published in English. The sample sizes varied between 20 and 397 individuals and consisted of craniofacial measurements from either living or deceased human skulls. Validity of the measurements was not determined in any of the studies, while six papers reported some form of reliability assessment. All the articles included multiple time points within the same population or data from multiple age groups. Growth of S-Ba was generally agreed to be from spheno-occipital synchondrosis growth. Basion displaced downward and backward and sella turcica moved downward and backward during craniofacial growth. Timing of cessation of S-Ba growth was not conclusive due to limited identified evidence. Conclusions: Current evidence suggests that S-Ba is not totally stable, as its dimensions change throughout craniofacial growth and a minor dimensional change is observed even in late adulthood.

“…A literatura mostra uma auto-correção desta má oclusão, se o hábito for interrompido na transição da dentição decídua para mista 29,30 . No entanto, o ideal é não aguardar essa autocorreção e sim realizar o tratamento o mais precocemente possível, antes que está má oclusão se torne irreversível 31 e promova alterações morfológicas com o passar do tempo, como atresia do arco maxilar.…”

ResumoA mordida aberta anterior é uma má oclusão caracterizada pela presença de um trespasse vertical negativo entre as bordas incisais dos dentes anteriores superiores e inferiores. A etiologia é multifatorial, entre eles estão à hereditariedade, hábitos de sucção digital e chupeta, interposição de língua e respiração bucal. Estes fatores tornam a má oclusão complexa, principalmente em relação a estabilidade, sendo necessário um tratamento multidisciplinar, envolvendo psicólogos, otorrinolaringologistas e fonoaudiólogos, para que o tratamento ortodôntico se torne mais preciso e eficiente, diminuindo o risco da instabilidade desta má oclusão. Na literatura há várias formas de tratamento, desde a utilização de aparelhos fixos mais complexos até tratamentos mais simples. O objetivo deste artigo foi descrever o tratamento estabelecido para um paciente com 13 anos de idade, apresentando uma mordida aberta anterior dentoalveolar, causada por hábito de sucção digital até os 9 anos de idade, que desencadeou uma interposição lingual e dificuldade de fonação adequada. O tratamento proposto foi uma ortodontia simples e efetiva por meio da extrusão dos dentes anteriores com o uso de elásticos intermaxilares, apoiados no aparelho ortodôntico fixo metálico pré-ajustado (Prescrição Andrews, slot 0.022") e controle clínico mostrando estabilidade após 2 anos. O tratamento ortodôntico realizado foi satisfatório, porém é necessário destacar a importância da participação da fonoaudiologia para que houvesse estabilidade da oclusão e retorno das funções musculares à normalidade.

AbstractThe anterior open bite is a malocclusion characterized by presence of a negative overbite between incisal surfaces of upper and lower anterior teeth. The etiology is multifactorial, including hereditary factor, pacificator and digital suction habits, tongue interposition and buccal breath. These factors become the malocclusion complex, mainly in relation to occlusal stability, being necessary a multidisciplinary treatment involving psychologist, otolaryngologist and audiologists for a more precise and efficient orthodontic treatment to decrease the risk for occlusal instability of this malocclusion. Literature describes several forms of treatment including complex fixed appliances to simple treatments. The aim of this article was to describe a treatment performed to 13-years old patient presenting a dentoalveolar anterior open bite caused by digital suction habit since 9-years old that evolved to tongue interposition and difficulty of adequate speech. The proposal treatment was a simple and effective orthodontic approach by extrusion of anterior teeth using intermaxillary chains supported by fixed pre-adjusted metallic orthodontic appliance (Andrews prescription, slot 0.022") and clinical follow-up for 2-years after treatment. The orthodontic treatment was satisfactory, but it's need to highlight the importance of participation of audiologist to achieve final stability of occl...
