Reaproveitamento imediato da ação expansora em um caso de expansão rápida da maxila assistida cirurgicamente

Immediate reutilization of the expanding action in a case of rapid maxillary expansion surgically assisted. The orthopedic rapid maxillary expansion (RME) and rapid maxillary expansion surgically assisted (RMESA) are conducted with the aim of giving an appropriate jaw, capable of providing a normal occlusion. In extreme cases, where there is a severe atresia, it is necessary to perform an expansion beyond that allowed by the expander, followed by another conventional device or a butterfly expander, when the atresia is in the anterior maxillary region. In this situation, there are two options: wait about 90 days to allow intermaxillary suture restructuring and perform a new RME / RMESA or proceed immediately to the expansion process. Considering the biological cost, financial and clinical time, the procedure of reusing the immediate expander action becomes the technique of choice in these cases, been the operational procedure performed simplified and in just four steps. This work will show a case report where, after accomplishing the RMESA was observed that even after changing the shape of the maxillary arch, the severity of atresia could not be corrected, especially in the anterior region, and more expansion was needed. Aiming to correct the atresia in the anterior maxilla, the technique used was to reuse the immediate expander action through the change of an intraoral screw expander for a conventional butterfly type screw expander.

Efeitos esqueléticos e dentários decorrentes da expansão rápida maxilar

This study evaluated the maxillary transversal changes caused by the rapid maxillary expansion (RME) accomplished by Hyrax appliance. Sixteen children from both genders were selected and treated, with ages between 7.7 to 10.8 years, who presented unilateral or bilateral posterior crossbite. Postero-anterior radiographs were taken at the beginning of the treatment, end and post-retention period. The treatment promoted an average opening of 8.8 mm of IMD (intermolar distance), 2.33 mm of IAD (interapex distance) and none of IID (interincisal distance). At the end of retention period, relapse was observed, with a decrease of 4.3 mm of IMD, 1.23 mm of IAD, a non-significant enlargement of IID (0,38 mm).These results confirm the significant influence of Hyrax appliance on transverse dimensions, represented by enlargement of IMD and IAD and its effectiveness to solve posterior crossbites.

Matriz Bertholdo/Ricci/Barrotte (BRB): uma simplificação de técnica para obtenção de guia de estratificação com compósitos

Advanced Layering composite resins can be facilitated by a technique called "Lingual Matrix", where a guide is made of elastomer by molding a previously waxed tooth or sculped in an intraoral test drive restoration. This technique has many advantages to sophisticated layering, facilitation stratification, anatomic construcrion and the stages of finishing and polishing. However, in some clinical situations, the unfolding of the steps to obtains this matrix can be time consuming or even infeasible. To facilitate the achievement of this apparatus, a technique was idealized allowing significant reducrion in clinical time. This matrix, called the "BRB Matrix" is widly discussed in a didactic and clinical manner in this article, presenting its advantages in clinical cases where it is imperative to use a guide for conduction a controlled layering. The simplicity of this approach, as well as reduced clinical time and finacial costs turn it feasible in an everyday clinical practice.

Correção da deficiência transversa da maxila por meio da expansão rápida da maxila cirurgicamente assistida

Fundamentation: The correction of maxillary transverse deficiencies involves orthodontic and surgical procedures that can be performed before or after skeletal maturity. The surgically assisted rapid maxillary expansion (SAR ME) is performed by osteotomies through the lateral walls of the maxilla, zygomatic and canines buttresses, palatal and pterygomaxillary sutures, causing the maxillary disjunction. Followed by activation of the expander to the desired over-expansion in order to correct intercuspal later. Objective: The purpose of this study was to discuss the issues involved in the diagnosis of maxillary atresia, SAR ME indications, as well as surgical technique, through a case study. Methods: The male patient, 19 years old, had severe transverse maxillary deficiency with facial pattern III , Class III , with great lip incompetence. The patient underwent general anesthesia in a hospital environment, the osteotomies was done according to the technique described by Epker and Wolford (1980). Postoperatively, the patient underwent activations daily for 15 days and after 6 months, the orthodontist installed fixed orthodontic appliance to prepare the patient to orthognathic surgery later. Conclusion: The diagnosis by clinical evaluation and models study is essential for the indication of SAR ME and this procedure provides good predictability in the correction of transverse deficiency, with minimal morbidity.

Atresia maxilar em adultos: simplificação da técnica cirúrgica

A expansão rápida da maxila cirurgicamente assistida (ERMCA) é realizada por meio de osteotomias nos pilares da maxila e na sutura palatina mediana, promovendo a correção da deficiência transversa da maxila. Técnicas menos invasivas foram descritas, visando à realização desses procedimentos sob anestesia local, eliminando os custos de internação hospitalar e trazendo maior conforto aos pacientes. A proposta deste trabalho foi discutir os aspectos envolvidos na simplificação da técnica da ERMCA sob anestesia local por meio do relato de caso clínico-cirúrgico de paciente com 27 anos de idade. Conclui-se que o diagnóstico por meio da avaliação clínica e dos modelos de estudo é essencial para a indicação da ERMCA e esse procedimento proporciona boa previsibilidade na correção da deficiência transversal, com mínima morbidade. Além disso, a utilização de uma técnica minimamente invasiva é efetiva no tratamento de maxilas atrésicas, com índices de recidiva semelhantes aos das técnicas mais invasivas.

Complicações após expansão de maxila cirurgicamente assistida

Introduction: The treatment of adult transverse maxillary deficiency is the surgically assisted maxillary expansion. Several surgical techniques have been described for this and complications have been related to these procedures. Objective: the aim of this study was evaluate the incidence of complications associated with surgically assisted maxillary expansion. Material and method: 33 individuals undergone surgically assisted maxillary expansion by subtotal Le Fort I osteotomy with a step in the zygomatic-maxillary buttress and associated to pterigomaxillary disjunction and osteotomy of intermaxillary suture. Operative complications, post-operative complications and the distance between the upper teeth were recorded. Result: 12 men and 21 women with an average age of 24.64 years undergone the procedure. The interdental distances increased from preoperative to 2 months post?operative time. The prevalent complications were sinusitis (6%) and teeth displacement and inclination (6%). Conclusion: Surgically assisted maxillary expansion is an effective and low morbidity procedure to treat transverse maxillary deficiency in adults.

Rehabilitative treatment of cleft lip and palate: experience of the Hospital for Rehabilitation of Craniofacial Anomalies/USP (HRAC/USP) – part 4

Treatment of patients with cleft lip and palate is completed with fixed prostheses, removable, total, implants and aims to restore aesthetics, phonetics and function and should be guided by the basic principles of oral rehabilitation, such as physiology, stability, aesthetics, hygiene and the expectations of the patient. In order to obtain longevity of a prosthetic rehabilitation, the periodontal and dental tissue as well as the biomechanics of the prosthesis are to be respected. The purpose of this article is to describe the types of prosthetics treatment, which are performed at HRAC/USP for the rehabilitation of cleft area in adult patients.

Prevalence of enamel defects in permanent teeth of patients with complete cleft lip and palate

Objective: To evaluate the prevalence, types, location, and characteristics of enamel defects in anterior permanent teeth of patients with complete unilateral and bilateral cleft lip and palate, as well as the relation with the cleft. Setting: Hospital for Rehabilitation of Craniofacial Anomalies, Bauru, São Paulo, Brazil. Participants: Eighty patients of both genders, 12 years and older, with unilateral or bilateral cleft lip and palate. Methods: A single examiner carried out clinical examination under artificial light with a dental probe and mirror after drying teeth according to the modified DDE index. Results: Seventy-four of 80 patients presented with at least one tooth affected by enamel defects: 165 of 325 evaluated teeth (50.8%) presented enamel defects, with hypoplasia being the most prevalent (50.7%), followed by diffuse opacity (23.1%) and demarcated opacity (18.4%). The most affected tooth was 21 (36.5%), followed by 11 (34%), located at the middle (40%) and incisal (33%) thirds. Most defects occur at the buccal surface (47.7%), followed by the distal (22.7%), the mesial (19%), and the palatal (10.6%) surfaces. A significant relationship was found between the cleft side and enamel defects. Conclusion: Upper anterior teeth of patients with complete cleft lip and palate present a high prevalence of enamel defects; the highest percentage on the cleft side suggests that the cleft does influence the occurrence of enamel defects in permanent teeth.
