Eficiência do aparelho Herbst bandado na correção da Classe II divisão 1 -relato de caso

The current reports the case of a young patient with malocclusion Class II division 1 on permanent dentition treated in two stages, rthopedics and orthodontics, respectively. At first, the banded Herbst appliance was used duringa 7 months period, followed by a T4K appliance, Trainer for Kids used as retention, and on the second stage the corrective Orthodontics was performed. The results showed the acquirement of a Class I dental relationship, which was kept stable, with excellent intercuspation, even after 5 years of the removal of the Herbst appliance, as well as the correction of the overjet and the reduction of the facial profile convexity. It can be concluded that the Herbst appliance was very efficient in correcting the Class II malocclusion, long term, also providing a very favorable effect on the facial profile.

Análise tomográfica da articulação temporomandibular no tratamento com Herbst em adulto jovem

Class II malocclusion features a high prevalence in Brazil, being considered as a routine in orthodontic clinics. A number of appliances are shown in the literature in order to correct Class II malocclusion with mandibular retrusion. Herbst´s fixed functional appliance, idealized by Emil Herbst (1905) and reintroduced, in the 1980´s, by Hans Pancherz is highlighted for maintaining the mandible continuously advanced, showing a shorter active treament time, an immediate esthetic impact on the facial profile, as well as requiring no patient´s commitment. Recent researches indicate the use of this appliance in individuals after pubertal growth surge. The aim of the present study is to show the orthodontics practitioner the option to use this appliance so as to treat Class II in individuals after the growth surge, obtaining satisfactory outcomes and further Class II correction.

Aparelho de Herbst associado a aparelhos fixos: descrição de técnica

This paper aims at describeconstruction and installation sequences of a new design of appliance that allows continuously protraction of the mandible, using the telescopic mechanism of the Herbst appliance. This appliance has the advantage to be easily assembled by the orthodontist, without the necessity of molding and the assistance of a specialized laboratory, as well as the constant permanence in the mouth of the patient for being fixed.

Camuflagem ortodôntica com dispositivos de ancoragem temporários ou cirurgia ortognática: parâmetros para a decisão

The polemical discussion between orthodontic therapeutic and surgical approaches with relation to borderline cases receives a new impulse with the emergence of temporary anchorage devices. This branch of Orthodontics has brought new treatment perspectives, but it has still been applied empirically, while the various factors involved in determining and conducting the treatment planning are neglected. The objective of the present study is to identify the several factors to be considered in both forms of treatment in order to provide the orthodontist with information that may contribute for the correct decision.

Tratamento da má-oclusão de classe II divisão 1 de Angle, com aparelho de Herbst splint metálico seguido de aparelho fixo, na dentição permanente

The Herbst appliance is currently one of the most used appliances for the correction of Class II division 1 with mandibular retrusion. When used in peak, or just after the peak of growth it can result in some skeletal gain, which is favorable to the correction of anteroposterior discrepancy with effective and stable results. This article aims to report a case of a patient with malocclusion Class II division 1 with mandibular retrusion, associated with maxillary protusion, treated in two stages: with Herbst splint metallic appliance followed by fixed appliance orthodontic treatment.

Descrição do aparelho VABB (Vertically Activated Bite Block) para o tratamento da mordida aberta anterior

Nowadays, the correction of skeletal vertical dysplasia is considered a great challenge in Orthodontics. The skeletal open bite treatment presents limitations related to vertical growth pattern, the extension of open bite and especially the stability, which is very questioned. The treatment of skeletal open bite is mostly realized by the inhibition of vertical alveolar posterior development (relative intrusion) or absolute intrusion of posterior teeth, through vertical forces, generated by the action of masticatory muscles. The purpose of this article is to present a new appliance for the treatment of skeletal open bite, the VABB (Vertically Activated Bite Block) or modified Bite Block, whose action mechanism is to limit the vertical development of the molars, by the action of facial muscles and two bilateral expansion screws that provide a counterclockwise rotation of the mandible. It will also be presented a clinical case and the technical steps for the construction of this appliance.

Fenologia reprodutiva e distribuição espacial de Oeceoclades maculata (Lindl.) Lindl. (Orchidaceae) em Cerrado do município de Mogi Guaçu, São Paulo, Brasil

Oeceoclades aculate (Lindl.) Lindl., an invasive orchid, was analyzed as to its reproductive phenology and spatial distribution, correlation between abundance of mature and immature individuals, and verifying these with microclimate patterns in the Cerrado (savanna-like vegetation) of Mogi Guacu, Sao Paulo State, Brazil. For the reproductive phenology 100 plants were followed and the distribution pattern was identified by the Morisita Index (MI) and the Variance Ratio/Average (R) in 20 plots of 20x10m, reduced to 10x10m afterwards. The phenology presented seasonality, with flowering from November to February, fructification from February to June, and dehiscence from June to July. Mature and immature individuals aggregated and correlated to each other, indicating dependence between the ontogenetic stages. The luminosity was the preponderant microclimatic factor in the allocation of plants. Seasonal climatic changes and intensity of anthropogenic disturbances seem to be more important for the establishment of the species than microclimate.

Desenvolvimento radicular de híbridos de mamona submetidos à adubação potássica

A deficiency of potassium at the beginning of the season affects the nutritional balance implicating the proper development of plants. The objective of this study was to evaluate the effect of potassium (K) in the root system development and production of dry matter of shoots of hybrid castor. The experiment was a 5 x 2 factorial scheme in a completely randomized design with four replications. The treatments consisted of five doses of K: 0, 25, 50, 100 and 200 ppm and two hybrids of castor (Lyra and Savana). After 45 days after emergence, there was a collection of shoot and root system of plants. The evaluations were: length, area, diameter and dry root and shoot. The addition of potassium caused increased root diameter at the hybrid Savana and reduced at the Lyra. The production of root and shoot dry of the hybrid Savana decreased with doses from 78 and 116 ppm of potassium, respectively.
