“…Open bite (OB) is one of the most common malocclusions in patients with orofacial dysfunction (OD) and syndromes [1], and in patients with intellectual and developmental disabilities [2,3]. Weak orofacial muscles, anterior positioning of the tongue, mouth breathing, and open mouth posture (OMP) are common findings in patients with open bites [4,5]. Myotonic dystrophy type 1 (DM1) and Duchenne muscular dystrophy (DMD) are progressive myopathies in which malocclusion, particularly lateral and anterior open bites, are common [6] Although both diseases result in muscle weakness, they differ with respect to pathogenetic mechanisms, course of the disease and clinical expression.…”

Open bite (OB) is a common malocclusion in individuals with orofacial dysfunction and syndromes, especially in neuromuscular diseases. Objectives: The objectives were to explore the prevalence of OB in myotonic dystrophy type 1 (DM1) and Duchenne muscular dystrophy (DMD) and to create and compare orofacial dysfunction profiles. Methods: In this database study, 143 individuals with DM1 and 99 with DMD were included. The Mun-H-Center questionnaire and observation chart were used together with the Nordic Orofacial Test –Screening (NOT-S) to create orofacial dysfunction profiles. OB was categorised as: lateral (LOB); anterior (AOB); severe anterior (AOBS); or both types of anterior OB (AOBTot). Descriptive and multivariate statistics were used to compare the OB prevalence and to study associations with orofacial variables, respectively. Results: There was a statistically significant difference in OB prevalence between the DM1 (37%) and DMD (49%) groups (p = 0.048). LOB was seen in < 1% of DM1 and 18% of DMD. LOB was associated with macroglossia and closed mouth posture, AOB with hypotonic lips, and open mouth posture and AOBS with hypotonic jaw muscles. The orofacial dysfunction profiles showed similar patterns, although the mean NOT-S total scores for DM1 and DMD were 4.2±2.8 (median 4.0, min-max 1–8) and 2.3±2.0 (median 2.0, min-max 0–8), respectively. Limitations: The two groups were not age- or gender-matched. Conclusion: OB malocclusion is common in patients with DM1 and DMD and is associated with different types of orofacial dysfunction. This study highlights the need for multi-disciplinary assessments to support tailored treatment strategies that improve or sustain orofacial functions.

There are several reasons for the onset of malocclusion, which promotes disharmonious development of the craniofacial structure and may involve various factors such as incorrect positioning of teeth, maxilla, mandible, lips, tongue, and/or cheeks, possibly accompanied by deleterious oral habits. Malocclusion is a common finding that affects facial aesthetics, smile, as well as masticatory and respiratory functions, occurring in a large portion of the world’s population. Hence, a correct and early diagnosis is necessary for malocclusion treatment. There are various available treatments aiming for early correction of malocclusions. This clinical case report will describe a possible treatment for correcting an anterior open bite during the mixed dentition associated with a deleterious oral habit. The Balters’ Bionator is a functional orthopedic dento-muco-supported appliance that harmonizes the muscles of the tongue, lips, and cheeks, and treats skeletal discrepancies. At the end of this orthopedic treatment stage, the patient achieved the objectives of this work and will continue her care in a pediatric dental clinical setting at the Federal University of Amazonas-UFAM for further analysis and additional dentomuco-skeletal corrections.

Existen varias razones por las cuales se instala la maloclusión y promueve un desarrollo desarmonioso de la estructura craneofacial, pudiendo involucrar diversos factores como la posición incorrecta de los dientes, maxilar, mandíbula, labios, lengua y/o mejillas, pudiendo estar presente hábitos bucales perjudiciales. La maloclusión es un hallazgo común que compromete la estética facial, la sonrisa, así como las funciones masticatorias y respiratorias, y se encuentra en gran parte de la población mundial, por lo que es necesario un diagnóstico correcto y temprano para el tratamiento de la maloclusión. Existen diversos tratamientos disponibles que buscan la corrección temprana de las maloclusiones. Este informe de caso clínico relatará un posible tratamiento para corregir la mordida abierta durante la dentición mixta asociada a un hábito bucal perjudicial, el Bionator de Balters es un dispositivo ortopédico funcional dento-muco-soportado que armoniza los músculos de la lengua, labios y mejillas, y trata las discrepancias esqueléticas. Al final de esta etapa de tratamiento ortopédico, la paciente logró alcanzar los objetivos de este trabajo y continuará su atención en el entorno clínico odontológico infantil en la Universidad Federal de Amazonas-UFAM para nuevas análisis del cuadro y otras correcciones dento-muco-esqueléticas.
