Herbst esplinte metálico fundido: novo modelo de confecção com Duralay

A má oclusão de Classe II é originária de vários fatores etiológicos e uma das características mais comum desta má oclusão é a retrusão mandibular3, por esse motivo, os aparelhos de avanço mandibular são eleitos para o tratamento e correção desta má oclusão. Um destes aparelhos é o Herbst, que apresenta várias formas de ancoragens na sua confecção10. Tradicionalmente, as bandas eram o sistema de ancoragem mais usado, no entanto, pela alta frequência de quebras as mesmas foram substituídas por esplinte metálico12. Esse aparelho quando confeccionado de cromo cobalto pelo método da prótese parcial removível, apresenta como desvantagens a quantidade de passos laboratoriais e a possível contração do metal, podendo ocasionar a má adaptação da estrutura metálica à boca do paciente. Dessa forma, este artigo apresenta um novo método de confecção do aparelho de Herbst esplinte metálico fundido com uso da Duralay e liga níquel cromo. Esse método diminui os passos laboratoriais, proporciona maior resistência à tração e minimiza a contração da estrutura metálica, pois a resina química Duralay proporciona menor expansão do que a cera2.

Tratamento ortodôntico da agenesia de incisivo lateral superior com envolvimento de fratura radicular de incisivo central superior

Patients with agenesis of maxillary lateral incisor must have in your planning functional and aesthetic considerations, important to the success of the treatment, regardless of whether the choice of treatment is closing or opening and maintenance of space for rehabilitation with prosthesis. This choice will depend on factors such as skeletal and tooth structure and profile. Children and adolescents are the group of individuals most exposed to trauma and fracture of the maxillary lateral incisor due to the activities they perform. Proper diagnosis and good treatment are essential to the success of the treatment. This article aims to report a case of agenesis of the maxillary lateral incisor along with the involvement of a root fracture of the maxillary central incisor. The orthodontic treatment was successfully finished with a favorable prognosis for the fractured incisor to stay in a esthetic and functional position.

Autopercepção e condições de saúde bucal em gestantes

This study ev aluated oral health indic ators by determining the pr evalence of dental c aries, periodontal diseases, prosthetic conditions and need in pr egnant women; identifi ed self-perceived oral health status and evaluated association bet ween variables. A clinical examination was performed in fi fty pregnant women assisted in the Preventive Dentistry Clinic-FOAr-UNESP using traditional oral health indicators: DMFT, C ommunity Periodontal Index ( CPI) and pr osthetic c onditions. A semi-struc tured questionnair e was applied to identify oral health perception and to collect sociodemographic variables. For data analysis, pregnant women were allocated in three groups according to their oral health perception (good, fair, poor) and compared according to clinical variables by the Kruskal-Wallis and Dunn tests. DMFT was high, all of them showed periodontal changes, most do not use and do not r equire any type of prosthesis; 36% considered their oral appearance as good. There was signifi cant diff erence between groups for the DMFT index and prosthetic need. It may be concluded that despite dental caries experience of pregnant women was found to be high, the prosthetic need have been detected in most of them and the presence of calculus was observed in all the volunteers, the majority considered their oral health status satisfactory.

Protese total fixa em função imediata confeccionada em resina composta indireta

Immediate functioning of osseointegrated implants has been widely employed in edentulous patients due to its safety and high predictability. However, viability and success of immediate-loaded implants is defined by factors such as number of implants, distribution and splinting, as well as reduction of oblique loads and excessive occlusal contacts. The indirect composite resin-modified glass enable building of a highly aesthetic prosthesis, combining satisfactory resistance and better force dissipation on occlusal loading. This article describes a resin composite, mandibular fixed prosthesis on osseointegrated implants in immediate function.

Protocolo mandibular com implantes curtos

Jaws atrophy represents a great challenge to Implantology regarding rehabilitation of edentulous areas. This paper reports an extreme mandibular atrophy with only 9mm of height between the mental foramina. In these situations, treatment options include bone augmentation techniques, transmandibular, or short dental implants. It is well accepted that bone grafts to improve height do not have good predictability. Besides, osteogenic distraction is associated with a great patient discomfort and transmandibular implants are related with high failure rates. Also, surgical-prosthetic rehabilitations with short dental implants had been associated to good success rates. The purpose of this clinical case is to report a severe mandibular atrophy, successfully treated with four short dental implants between mental foramina for implant-supported prosthesis.

Tratamento multidisciplinar: relato de casos clínicos

Introduction: Adult patients are more prone to periodontal disease mainly caused by poor plaque control. In these patients, orthodontic movement is not contraindicated, but it is necessary to evaluate their periodontal status so that we can establish the appropriate treatment plan. Objective: The objective of this article is to describe and discuss the clinical cases of severely periodontally compromised individuals in need of oral rehabilitation. Methods: The study consisted of orthodontic treatment of two cases with periodontal involvement. After clinical and radiographic examinations, the cases were analyzed by a multidisciplinary team of Orthodontics, Periodontics and Prosthodontics, in order to provide the patient with the best possible esthetic, functional and stability outcomes. Periodontal treatment consisted of supra and subgingival scaling prior to orthodontic treatment, and regular maintenance performed on a quarterly basis throughout orthodontic movement. Activation was carried out every 45 to 50 days, with light forces. Retention remains to the present day, even after completion of the rehabilitation. Conclusion: Multidisciplinary oral rehabilitation treatment yields satisfactory results. The interaction between Orthodontics and Periodontics reveals that patients with reduced, but healthy periodontium, can receive orthodontic treatment as long as the forces applied do not exceed patient's biological limits.

Efeito de um gel de peróxido de carbamida a 10% sobre a resistência de união de restaurações adesivas à dentina

The present study aimed to analyze the effects of tooth bleaching with 10% carbamide peroxide (CP) gel on the bond strength of resin composite restorations to dentin. Material and Methods: Twenty cavities were prepared on the buccal surface of bovine teeth. After acid etching and application of bonding agent on dentin and enamel, the cavities were restored with composite resin. The specimens were divided into groups according to treatment on the surface of enamel / restoration: G1 - control (no treatment) and G2 (10% PC gel application for 8h/day during 14 days). After this period, the teeth were cut to produce beams with 0.81 mm2 cross-sectional area, which were subjected to microtensile test. The fractures were examined with a stereomicroscope and classified as cohesive in resin or dentin, adhesive, or mixed. Results: The statistical analysis (ANOVA / χ2) revealed that the factor treatment interfered with the bond strength, which was significantly higher for specimens of G2 (p <0.05). Adhesive fractures occurred in most of specimens of both groups with values ranging from 48.3% to 75%. Mixed fractures were the second more frequent in G1 and cohesive resin failure in G2. Conclusion: It was concluded that tooth bleaching with 10% of PC increased the bond strength of adhesive restorations to dentin.
