The Rapid Maxillary Expansion that involves the opening of the median palatine suture is used frequently to correct narrow arch maxillary and since the maxillary relates also with the skull base, the objective of this paper was to search in the literature the effects that the Rapid Maxillary Expansion produces on the pterygoid process and the spheno-occipital synchondrosis; analyzed clinically, with compute tomography, bone scintigraphy, cephalometric X-ray and the finite element method. The literature review was done on the data bases: Medline (PubMed), Scopus, Scielo, BSV (Bireme), ISI (Web of Sciencie) and Lilacs. It can be said that the forces it proportionate during the Rapid Maxillary Expansion not only to performs on the median palatine suture, but also on the pterygoid processes and even on the spheno-occipital synchondrosis, to making displacements and different concentrations o...

The adult usually offers resistance to the conventional orthodontic treatments, due to the need of using visible brackets such as metallic or esthetic porcelain. The concept of Invisible esthetic Orthodontics or Lingual Orthodontics covers the expectations of this type of patient. The multibrackets technique with lingual instruments is approximately 25 years old and with the experience of the treated cases, we have conceived a totally formal technique. This article it is an up-to-date revision of the different publications of Lingual Orthodontics, where one keeps in mind the history and the development of the lingual appliance, the diagnosis and treatment plan, the clinical and laboratory phases, the lingual mechanotherapy, the current tendencies and perspectives of the future of the lingual technique.

According as age increases, growth decreases and Class III skeletal patterns become more stable. The objective of Class III malocclusion’s treatment in primary dentition is to get a favorable environment to achieve a better dentofacial development. This article’s objective is to give a theorical summary about treatment of Class III malocclusions in primary dentition, and to present a case report.

The treatment of various skeletal malocclusions in children and young’ patients are performed applying orthopedic forces, seeking to alter growth or open sutures in certain anatomical regions. The condyle (CO) and mandibular fossa (MF) are regions that have been subjected to intense forces awaiting bone remodeling as part of the treatment. Due to the classic two-dimensional records used to assess anatomical morphological changes, many results have been controversial. With the use of tomography and modern tomographic superposition techniques, it is possible to identify these morphological changes quantitatively and qualitatively in bone structures. An integrated literature review of the morphological alterations of the CO and the MF was performed using Computed Tomography (CT) and Cone Beam Computed Tomography (CBCT) in patients with Class II and Class III skeletal malocclusions who use...

Rapid Maxillary Expansion (ERM) has been classically described in the literature as a therapeutic procedure in the treatment of transverse maxillary deficiency. The aim of this study was to evaluate the cephalometric skeletal changes on the cranial base in growing patients who had undergone rapid maxillary expansion. The material consisted of lateral radiographs taken from ten growing patients (eight male and two female) with need of rapid maxillary expansion as part of their orthodontic treatment. The age range of the patients was 7.1 to 12.7 years, and the mean age was 10.6 ± 2.04 years. Lateral radiographs of each patient were taken before treatment (T1) and immediately after the active phase of treatment (T2). The evaluated variables were: NSBa angle, NBa/F.H. angle, SN/ENA-ENP angle, F.H./ENA-ENP angle, SN/F.H. angle, S-N distance, S-Ba distance and N-Ba distance. The data were sta...

The objective of the present work was to compare the relationship skeletal sagital applying KIM’S cephalograms,Steiner and Projection USP. It was carried out the study cephalometric in 100 radiographs ofpatient without growth, with ages you enter 18 to 30 years of both genders; that they attended the clinicof orthodontics of the Unit of Post Grade of San Marcos University among the years 2005-2010. Tothe respective results they were applied the statistical test of Kappa to see the existence of agreement inwhat concerns to the skeletal relationship, among the analyses by means of their evaluation scale, besidescomparative charts. The results showed a level of low agreement among Steiner - Kim (Kappa: 0,283)Steiner - Projection USP (Kappa: 0,341) Kim-USP (Kappa: 0,277). The biggest coincidence one observesbetween the cephalograms of Steiner and Projection USP and the minor between Kim an...

El objetivo del presente trabajo fue comparar la relación esquelética sagital aplicando los cefalogramas de Kim, Steiner y proyección USP. Se realizó el estudio en 100 placas radiográficas de pacientes sin crecimiento, con edades entres 18 a 30 años de ambos géneros; que asistieron a la Clínica de Ortodoncia de la Unidad de Post Grado de la Universidad Nacional Mayor de San Marcos entre los años 2005-2010. A los respectivos resultados se les aplicó la prueba estadística de Kappa para ver la existencia de concordancia en lo que respecta a la relación esquelética, entre los análisis. Los resultados mostraron un nivel de concordancia estadísticamente significativo, pero bajo: entre Steiner - Proyección USP (Kappa: 0,341), Steiner - Kim (Kappa: 0,283) y Kim-USP (Kappa: 0,277). La mayor coincidencia se observó entre los cefalogramas de Steiner y Proyección USP y la menor ent...

RESUMEN Objetivo. El objetivo de este estudio fue comparar las discrepancias cefalométricas de Steiner, Tweed e Interlandi en pacientes con relación esquelética Clase I (según proyección USP). Material y métodos. Se estudiaron los cefalogramas laterales de 100 pacientes.Cada película cefalométrica fue trazada encontrándose la posición inicial y final del incisivo inferior con su correspondiente discrepancia cefalométrica. Los promedios de las discrepancias cefalométricas de los tres grupos fueron comparados en pares usando el Test de Wilcoxon, y para comparar los tres grupos se utilizó el Test de Friedman. Resultados. Se encontró un valor promedio para Steiner de -4,084mm, para Interlandi de -4,325mm, presentando ambas mayor variabilidad que Tweed quien obtuvo un promedio de -2,702mm. Los valores de las discrepancias cefalométricas propuestas por Steiner, Tweed e Interland...

A 22 year old woman with mesofacial biotype, skeletal class I and good lips profile, presented an Angle malocclusion class I with good intercuspidation of molars and premolars, moderate crowding in both arches, discrepancy of anterior Bolton for inferior excess, and decreased overjet and overbite. She was treated with a orthodontics treatment with extraction of a lower incisor, an atypical extractions in orthodontics. The success of this type of treatment needs a deep and meticulous diagnostic record, because this election of treatment will depend on a series of minimum requirements.

Mujer de 22 años de edad con biotipo mesofacial, patrón esquelético de Clase I y buen perfil de labios, presentó una maloclusión de Angle de Clase I con buena intercuspidación de molares y premolares, con apiñamiento moderado superior e inferior, discrepancia de Bolton anterior por exceso inferior y overbite y overjet disminuidos. Se realizó un tratamiento de ortodoncia con la extracción de un incisivo inferior, una de las extracciones atípicas en ortodoncia. El éxito de este tipo de tratamiento requiere de un profundo y minucioso registro diagnóstico en ortodoncia, ya que su elección dependerá de que el caso clínico reúna una serie de requisitos.

The aim of this study was to determine the impact and relationship of Early Childhood Caries (ECC) and Quality of Life Related to Oral Health (QLROH) of children treated at the Service of the National Institute of Infant Health. Lima Perú. Methodology: It is a cross-sectional study; a representative sample of 95 children under 71 months and their mothers were selected randomly. The perception of mothers of QLROH were collected through the questionnaire ECOHIS (Early Childhood Oral Health Impact Scale). ECC data were collected through a clinical examination by two previously calibrated examiners (kappa˃0.81) using ICDASII criteria. The relationship between ECC and QLROH was performed using Spearman correlation. Results: The median and interquartile deviation simple of ECOHIS was 20 ± 5 with respect to the impact on the family 7 ± 1, impact on the child 13 ± 3.5. In the correlation an...
