“…Mouth breathing can also cause muscle imbalance, postural axis alteration, disorganization of muscle groups, inhibition of nasal afferent nerves, decreased pulmonary compliance, and restricted chest expansion as well as alveolar ventilation. 2 Once the nasal airway is obstructed, reducing airflow, the patient starts breathing through the mouth, causing air to arrive faster to the lungs. With less effort to breathe, the entire ventilatory mechanism is compromised, with reduced diaphragm action and less strength of the respiratory muscles.…”

Objectives: To assess alterations in respiratory muscle strength and inspiratory and expiratory peak flow, as well as skeletal and dental changes in patients diagnosed with transverse maxillary deficiency before and after microimplant-assisted rapid maxillary expansion (MARPE). Materials and Methods: Twenty patients (13 female and 7 male) were assessed by respiratory tests in three different periods: T0 initial, T1 immediately after expansion, and T2 after 5 months. Tests included: maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP), oral expiratory peak flow, and inspiratory nasal flow. Cone-beam computed tomography measurements were performed in the maxillary arch, nasal cavity, and airway before and immediately after expansion. Results: There was a significant increase in MIP between T0 and T2 and MEP between T0 and T1 (P<.05). Oral and nasal peak flow increased immediately after and 5 months later, especially in patients with initial signs of airway obstruction (P<.05). In addition, after expansion there was a significant enlargement of the nasal cavity, alveolar bone, and interdental widths at the premolar and molar region. Molars tipped buccally (P<.05) but no difference was found in premolar inclination. MARPE increased airway volume significantly. Conclusions: Skeletal changes promoted by MARPE directly affected airway volume, resulting in a significant improvement in muscle strength and nasal and oral peak flow.

“…Aunque en los incisivos superiores en personas con clase esqueletal III puede existir protrusión de estos, (19) Los resultados del estudio que se presenta arrojaron la presencia de retrusión, mostrando un patrón de crecimiento dental invertido debido a la malformación de labio y paladar hendido, lo que guarda similitud con lo observado por Liu et al, (20) Los que, además, encontraron un predominio de esa malformación en pacientes de género femenino. Al respecto, Madrid y Barhoum (21) también reportaron una retro inclinación evidencida a través de ángulos negativos (1/NA de -26°).…”

El trabajo investigativo buscó determinar las diferencias de tipo esqueletal y de inclinación dental que se exhibe comparando medidas cefalométricas de personas con labio y paladar hendido (LPH) y personas con ausencia de cualquier trastorno bucofacial. El estudio fue de tipo observacional, descriptivo y transversal utilizando radiografías laterales de cráneo archivadas en historias clínicas de 20 individuos con labio y paladar hendido frente a 20 individuos sin fisuras bucofaciales de entre 6 y 16 años de edad. Manualmente, se realizaron los análisis cefalométricos donde el 100% de los pacientes con labio y paladar hendido presentaron clase III esqueletal, en tanto que, los individuos sin fisuras abarcan el 50% en clase I, 35% clase II y 15% clase III. La inclinación dental preponderante para los individuos con labio y paladar hendido fue de proinclinación para el incisivo inferior y retroinclinación para el incisivo superior, en tanto, el grupo de control presenta mayor proinclinación en el incisivo superior y normo inclinación para el incisivo inferior. Se logró establecer diferencias estadísticamente significativas en la inclinación del incisivo superior del grupo de control y del grupo de estudio (p=0,002; t=3,25; gl=38), además, diferencias estadísticamente significativas entre la discrepancia ósea del grupo de control y del grupo de estudio (p=0,00; U=9).

“…1 Thus, as a literary corollary, the NSARME technique is adequate for patients with incomplete maxillary bone maturation and transverse maxillary deficiency that cannot be corrected by fixed apparatus. 4,5 Another indirect benefit of maxillary expansion techniques is the improvement of upper airflow reducing respiratory distress, promoting the increase of air cavity. 5 Thus, the most accepted age for performing NSARME varies widely according to the literature, being proposed for patients with a maximum age of 14 years in women and 16 years in men, according to.…”

“…SARME can be performed by maxillary osteotomy and rafepalatine associated with a palatal expander, or LeFort I osteotomy associated with maxillary segmentation. 4,5 From the Haas dental orthodontic expander, many others were developed, including the modified Haas and the Hyrax apparatus. 6 The latter is a supported dento expander that leads to greater posterior dentoalveolar inclinations, if compared as Haas expander.…”

Introduction: In the context of rapid maxillary expansion, transverse deficiencies are the main predictors of dentofacial deformities with high prevalence in dental practice. In this sense, the techniques of surgically assisted rapid maxillary expansion (SARME) and non-surgically assisted rapid maxillary expansion (NSARME) are used in order to correct maxillary development through palatal disjunction. Objective: to analyze the main considerations of rapid maxillary expansion, showing its main indications, contraindications, types of expanders, as well as the main dental and skeletal changes produced by them. Methods: We searched the databases EBSCO, SCIELO, PubMed / MEDLINE and Academic Google in the period 2003 to 2018. The main descriptors (Mesh Terms) were Rapid expansion of the maxilla, Rapid assisted surgery of the maxilla, Rapid non-surgical maxillary expansion, Circuit breakers and Clinical studies. Main Finding: The use of the Hyrax expander has become a poorly indicated procedure since the vast majority of patients with maxillary atresia also have other vertical and / or sagittal discrepancies in the bony bases of the face. In this context, however, the rapid expansion of the surgically assisted maxilla presents as a safe and easy procedure to be performed in the office, and is also a low-cost and acceptable procedure for patients. Conclusion: Based on the literary findings, there is still no consensus on which is the best jaw breaker, and it is necessary to increase the number of clinical and randomized studies, with eligibility criteria that can in fact homogenize the participants. In addition, the literature has clearly shown that it is imperative that dental surgeons have the knowledge and clinical experience to be able to indicate the best procedure for each patient, that is, the rapid expansion of the non-surgical or surgical maxilla.
