Introdução: A hipoplasia transversal maxilar superior é um problema comum na região craniofacial, frequentemente acompanhada por apinhamento dentário, mordida cruzada e desvio mandibular. A sua etiologia é multifatorial, incluindo fatores genéticos e hábitos parafuncionais. A expansão maxilar tem sido um tratamento eficaz, especialmente quando realizada antes do pico de crescimento ósseo. A expansão maxilar influência positivamente a respiração nasal e pode corrigir desvios do septo nasal. Materiais e métodos: Este estudo retrospetivo é descritivo e observacional, realizado na Clínica Universitária da Universidade Católica Portuguesa de Viseu nos últimos dois anos. A amostra é constituída por 30 indivíduos, divididos por género e distribuídos em duas faixas etárias: 6-10 anos e 11-14 anos. Os critérios de inclusão incluíram pacientes com dentição mista, atresia maxilar, má-oclusão e apinhamento na arcada superior. Os critérios de exclusão incluem pacientes adultos, tratamentos iniciados antes de 2020 e todos aqueles que apresentavam dentição definitiva ou cirurgia maxilar anterior à expansão. Resultados: A maioria dos participantes estava na faixa etária de 6 a 10 anos, com predominância da classe I esquelética. A presença de parafunções, especialmente respiração oral, foi comum. O expansor Hyrax foi amplamente utilizado e mostrou-se eficaz, especialmente em pacientes com parafunções. Este estudo analisa as consequências do palato estreito no desenvolvimento dentário, esquelético e funcional infantil. Discussão: A intervenção precoce na expansão maxilar, especialmente entre 6 e 10 anos, é crucial para resultados ideais e poucos efeitos secundários. O uso eficaz do expansor Hyrax em pacientes com parafunções indica sua viabilidade como opção de tratamento para a expansão maxilar. Conclusão: Este estudo enfatiza a necessidade de planos de tratamento para diagnóstico precoce em crianças com anomalias e hábitos parafuncionais. Destaca-se a expansão maxilar para melhorar a respiração e o sono, sugerindo investigações sobre a eficácia do aparelho Hyrax em melhorar dimensões transversais e condições funcionais.
Introduction: Upper jaw transverse hypoplasia is a common problem in the craniofacial region, often accompanied by dental crowding, crossbite and mandibular deviation. Its aetiology is multifactorial, including genetic factors and parafunctional habits. Maxillary expansion has been an effective treatment, especially when performed before the peak of bone growth. Maxillary expansion positively influences nasal breathing and can correct deviations of the nasal septum. Materials and methods: This is a retrospective descriptive and observational study carried out at the University Clinic of the Portuguese Catholic University of Viseu over the last two years. The sample consisted of 30 patients, divided by gender and distributed into two age groups: 6-10 years and 11-14 years. The inclusion criteria included patients with mixed dentition, maxillary atresia, malocclusion and crowding in the upper arch. Exclusion criteria included adult patients, treatments started before 2020 and all those with permanent dentition or maxillary surgery prior to expansion. Results: The majority of participants were aged between 6 and 10 years, with a predominance of skeletal class I. The presence of parafunctions, especially mouth breathing, was common. The Hyrax expander was widely used and proved effective, especially in patients with parafunctions. This study analyzes the consequences of a narrow palate on dental, skeletal, and functional development in children. Discussion: Early intervention in maxillary expansion, especially between ages 6 and 10, is crucial for ideal results with minimal side effects. The effective use of the Hyrax expander in patients with parafunctions suggests its viability as a treatment option for maxillary expansion. Conclusion: This study highlights the need for comprehensive treatment plans for children to enable early diagnosis of anomalies and parafunctional habits. It emphasizes maxillary expansion to improve breathing and sleep. Further research on the Hyrax appliance's effectiveness in enhancing transversal dimensions and related functional conditions is suggested.
