The midpalatal suture of 18 children submitted to rapid palatal expansion with the Haas fixed expander and ranging in age from 5 years 2 months to 10 years 5 months was evaluated with computerized tomography. The posterior nasal spine undergoes the impact of RPE in patients in the primary and mixed dentition stages, similarly to the anterior nasal spine though to a lesser extent. The average opening of the midpalatal suture was 2.21 mm in the anterior nasal spine region and 0.95 mm in the posterior nasal spine region.

Introduction. Microimplant-assisted rapid palatal expansion (MARPE) has been considered an alternative to avoid extensive surgical procedures. In order to obtain skeletal results of MARPE, force should be enough to overcome areas of resistance and the first one that is required to be disrupted is the midpalatal suture, which becomes increasingly interdigitated after adolescence. Objective. The present study aimed at providing a novel approach using a minimally invasive method called corticopuncture (CP) in association with MARPE illustrated by a case report of a 35-year-old Brazilian female Caucasian patient presenting maxillary transverse deficiency. Method. Treatment plan started with an orthopedic correction of the transverse problem using a MARPE device. After many unsuccessful attempts to activate MARPE, corticopunctures were performed along the midpalatal suture. CP procedure at the midpalatal suture included 8 perforations (2 mm apart), performed after previous predrilling followed by miniscrew insertion (5 mm thread length and 1.8 mm diameter). Results. After CP and new activation protocol, the opening of the midpalatal suture was observed by CBCT images, showing skeletal results, suture split of 3.14 mm (premolar area) and 2.06 (molar area), an increase of 4.3 mm (premolar) and 3.03 mm (molar) in basal bone width, 4.43 mm (premolar) and 3.1 mm (molar) in cortical bone width, and minimal dental effects (mean of 1.2° of tooth tipping). Conclusion. The combination of MARPE and corticopuncture method was proved to be a nonsurgical treatment option to correct maxillary transverse deficiency in an adult patient. CP was able to weaken suture interdigitation thus facilitating the split.

The aim of this prospective study was to evaluate the midpalatal suture in children submitted to rapid palatal expansion, at the end of the retention stage, with CT scans. The sample was comprised of 17 children aged between 5 years 2 months and 10 years 5 months. The tomographic images showed that the midpalatal suture was completely ossified from the anterior nasal spine area to the posterior nasal spine area at the end of the retention phase, that is, 8 to 9 months postexpansion.

Abstract This study aimed at modifying the method for obtaining an axial cut of the maxilla, considering the palatine anatomy, for evaluation of the maturation stage of the midpalatal suture (MPS) and to compare this modified method with the original one.The sample consisted of 84 cone-beam computed tomography (CBCT) scans of 40 boys and 44 girls, aged 11 to 15 years. The files were exported to the Nemotec Dental Studio program, which was used to obtain axial cuts of the maxilla so as to follow the palatine anatomy, keeping the buccal and nasal cortical bones centralized and equidistant. Two previously calibrated evaluators classified the axial images of the MPS into 5 maturational stages (A, B, C, D, and E) according to suture morphology. Kappa test was used to test intra and inter-examiner agreement and the sign test was used to compare the results of this study with those from the original method. Statistical significance level was set at 0.05%. The kappa values for intra and inter-examiner agreement were 0.88 and 0.69, respectively. The modified method was able to evaluate the MPS maturation status and could demonstrate stages of maturation in more detail than the original method.  Classification of the MPS maturation with the curved suture axial cut of this method is similar to the original method, with the advantage of allowing evaluation of maturation in the midline of the palate, even when the palate was curved and/or thick. Keywords: Sutures. Maxilla. Palatal Expansion Technique. Resumo Este estudo visou modificar o método para a obtenção de um corte axial da maxila, considerando a anatomia do palato, para avaliação da maturação da sutura palatina (SPM) e para comparar este método modificado com o original.  A amostra foi composta de 84  tomografias computadorizadas (TCFC) de 40 meninos e 44 meninas, com idades entre 11 a 15 anos. Os arquivos foram exportados para o programa Nemotec Dental Studio, que foi usado para obter cortes axiais da maxila de modo a acompanhar a anatomia do palato, mantendo a cortical óssea  vestibular e nasal centralizada e equidistante. Dois avaliadores previamente calibrados, classificaram as imagens axiais da SPM em 5 fases de maturação (A, B, C, D, e E) de acordo com a morfologia da sutura. O Teste Kappa foi usado para testar concordância intra e inter-examinador e o teste do sinal foi utilizado para comparar os resultados deste estudo com os do método original. O nível de significância estatística foi de 0,05%. Os valores de kappa para concordância intra e inter-examinador foram 0,88 e 0,69, respectivamente. O método modificado foi capaz de avaliar o estágio de maturação da SPM e pode demonstrar estágios de maturação em mais detalhe do que o método original. A classificação da maturação  da SPM com o corte axial curvo deste método é semelhante ao método original, com a vantagem de permitir a avaliação da maturação na linha média do palato, mesmo quando o palato for curvo e/ou espesso.
