          Abstract

          RESUMEN Introducción: Evaluar la maduración de la sutura palatina mediana (SPM) es importante en ortodoncia y ortopedia dentofacial, para decidir el tipo de tratamiento para expansión palatina, en pacientes con compresión maxilar. Angelieri et al. el 2013, proponen un método de evaluación de maduración de la SPM con tomografía computarizada de haz cónico. No se encontraron publicaciones que analicen artículos que describen y aplican el método de Angelieri. El propósito de esta revisión es analizar el método de Angelieri, describiendo usos, ventajas y desventajas. Revisión: El método de Angelieri clasifica la maduración de la SPM en 5 etapas (A-E). Su uso complementa a estudios con radiografías convencionales cuando éstas indican que el paciente está en etapas circumpuberales y post peak puberal. La identificación de la etapa de maduración de la SPM permite determinar las alternativas de tratamiento -ortopédico o con enfoque quirúrgico-, de acuerdo a si la SPM está sin osificación o con osificación parcial/total, respectivamente. Algunas ventajas del método de Angelieri son ser un método no invasivo, y reproducible tras una adecuada formación. Una de sus desventajas es la falta de un gold standard que compruebe que la morfología imagenológica de la SPM propuesta por los autores no es solo teórica. Conclusiones: El método de Angelieri es útil para evaluar la maduración de la SPM, previa calibración. No existe acuerdo en que el método de Angelieri sea predictor de éxito del tratamiento para expansión palatina. Se requiere mayor investigación acerca de la contribución de este método para su uso clínico.

          ABSTRACT Introduction: Assessing the maturity of the midpalatal suture (MPS) is important in orthodontics and dentofacial orthopedics, to decide the type of treatment for palatal expansion, in patients with maxillary compression. Angelieri et al. in 2013, proposed a method for evaluating the maturation of MPS with cone-beam computed tomography. No publications were found which analyze articles describing and applying the Angelieri's method. The purpose of this review is to analyze the Angelieri's method, describing its uses, advantages and disadvantages. Review: Angelieri's method classifies MPS maturation into 5 stages (A-E). Its use complements studies with conventional bi-dimensional radiographs, when they indicate the patient is in circumpubertal and post-peak pubertal stages. The identification of the stage of maturation of MPS allows to determine the treatment alternatives -orthopedic or with a surgical approach-according to whether MPS is without ossification or with partial/total ossification, respectively. Some advantages of the Angelieri's method are being a non-invasive method, and reproducible after adequate training. One of its disadvantages is the lack of a gold standard that proves the imaging morphology of MPS proposed by the authors is not only theoretical. Conclusions: Angelieri's method is useful to evaluate the maturation of MPS, after calibration. There is no agreement that Angelieri's method is a predictor of treatment success for palatal expansion. Further research is required on the contribution of this method to its clinical use.

          Midpalatal suture maturation: classification method for individual assessment before rapid maxillary expansion.

          In this study, we present a novel classification method for individual assessment of midpalatal suture morphology. Cone-beam computed tomography images from 140 subjects (ages, 5.6-58.4 years) were examined to define the radiographic stages of midpalatal suture maturation. Five stages of maturation of the midpalatal suture were identified and defined: stage A, straight high-density sutural line, with no or little interdigitation; stage B, scalloped appearance of the high-density sutural line; stage C, 2 parallel, scalloped, high-density lines that were close to each other, separated in some areas by small low-density spaces; stage D, fusion completed in the palatine bone, with no evidence of a suture; and stage E, fusion anteriorly in the maxilla. Intraexaminer and interexaminer agreements were evaluated by weighted kappa tests. Stages A and B typically were observed up to 13 years of age, whereas stage C was noted primarily from 11 to 17 years but occasionally in younger and older age groups. Fusion of the palatine (stage D) and maxillary (stage E) regions of the midpalatal suture was completed after 11 years only in girls. From 14 to 17 years, 3 of 13 (23%) boys showed fusion only in the palatine bone (stage D). This new classification method has the potential to avoid the side effects of rapid maxillary expansion failure or unnecessary surgically assisted rapid maxillary expansion for late adolescents and young adults.

            Effects of rapid maxillary expansion on the cranial and circummaxillary sutures.

            The aim of this study was to determine whether the orthopedic forces of rapid maxillary expansion cause significant quantitative changes in the cranial and the circummaxillary sutures.

              Age-dependent three-dimensional microcomputed tomography analysis of the human midpalatal suture.

              The success of rapid maxillary expansion is hard to predict in patients from the age of 20. There are as yet no reliable parameters enabling us to define success or failure a priori. The aim of this study was thus to use micro-CT techniques to quantify suture morphology three-dimensionally, and investigate its relation to age. The morphology of the midpalatal suture was evaluated by documenting 28 human-palate specimens from individuals aged 14-71 using computed tomography. The software AMIRA 3.00 was used for 3D (three-dimensional) reconstruction of the datasets. Sutural morphology was quantified and examined for age-dependent morphological characteristics with the software Image Tool 3.00. To that end, the specimens were assigned to three age groups ( /= 30 years) and the following parameters were considered: obliteration index in the frontal plane, and suture length, linear sutural distance, and interdigitation index in the horizontal plane, as well as bone density (BV/TV [%]) in the sagittal plane. Significant differences between age groups were only found for bone density in sagittal dimension. The middle-aged group exhibited the highest bone density (53.2%). In comparison to that group, bone density was significantly lower in the youngest and the oldest age groups. The mean obliteration index exhibited substantial inter-individual variation, was generally low, and did not correlate with chronological age. The extent of interdigitation was independent of age. The necessity for surgical weakening can neither be explained by sutural interdigitation increasing with age nor by a higher obliteration index. Sutural bone density (hence the fracture resistance increasing with age) seems to be the parameter limiting conservative RME.
