Abstract(s)
A maloclusão de Classe III, embora não tenha muita prevalência, retrata um grande desafio em termos de abordagem terapêutica e estabilidade pós-terapêutica para os Médicos Dentistas. Quando os sinais de qualquer tipo de maloclusão são identificados, é de extrema importância efetuar o tratamento preventivo e intercetivo na dentição decídua ou dentição mista precoce, de forma a corrigir os problemas existentes, intercetar os problemas em desenvolvimento para evitar o agravamento destes.
A maloclusão de Classe III esquelética provém de uma alteração da posição sagital dos maxilares podendo existir uma maxila retrognata, uma mandíbula prognata ou uma combinação dos dois.
Este trabalho tem como propósito descrever e acompanhar três pacientes pediátricos que se encontram em tratamento ortodôntico de classe III na consulta de ortodontia assistencial. O primeiro paciente apresenta dentição mista, maloclusão classe III esquelética, classe I dentária e utiliza Máscara Facial associada ao disjuntor McNamara superiormente e um expansor fixo inferior FLEA. A segunda paciente, também com dentição mista, apresenta uma classe III esquelética severa, classe III dentária e utiliza Máscara Facial em associação ao disjuntor acrílico McNamara. A última paciente possui dentição mista, classe III dentária, tendência de crescimento para uma classe III esquelética e utiliza um aparelho removível funcional Simões Network 3 (SN3) com um parafuso de expansão sagital e transversal.
Apesar dos resultados obtidos não serem finais, é possível afirmar que o tratamento preventivo e intercetivo em crianças com dentição mista precoce é mais efetivo durante o desenvolvimento esquelético e dentário. Os fatores ambientais/genéticos e as discrepâncias oclusais e esqueléticas afectam a dentição e a morfologia facial. A eliminação deste fatores é importante para alcançar os objetivos dos tratamentos.
Class III malocclusion, despite the fact that it is not very prevalent, represents a major challenge for dentists in terms of therapeutic approach and post-therapeutic stability. When the signs of any type of malocclusion are identified, it is extremely important to implement preventive and interceptive treatment in the deciduous or early mixed dentition, in order to correct the existing problems, intercept developing problems and prevent them from aggravating. Skeletal Class III malocclusion is the result of an alteration in the sagittal position of the jaws, which may include a retrognathic maxilla, a prognathic mandible or a combination of the two. The purpose of this study is to describe and follow up three pediatric patients undergoing Class III orthodontic treatment in the clinical orthodontic appointment. The first patient has mixed dentition, skeletal class III malocclusion, dental class I and uses a Face Mask associated with a McNamara expander superiorly and a FLEA fixed expander inferiorly. The second patient, also with mixed dentition, has severe skeletal class III, dental class III and uses a Face Mask in association with the McNamara acrylic expander. The last patient has mixed dentition, dental class III, a growth trend towards skeletal class III and uses a functional removable appliance Simões Network 3 (SN3) with a sagittal and transverse expansion screw. Although the results obtained are not final, it is possible to state that preventive and interceptive treatment in children with early mixed dentition is more effective during skeletal and dental development. Environmental/genetic factors, occlusal and skeletal discrepancies affect the dentition and facial morphology. Eliminating these factors is important to achieve the desired treatment.
