Proposta de um dispositivo para ajuste automático da altura de uma cama hospitalar

This paper proposes a mechanical device to adapt a simple model of hospital bed used in the Emergency Department at Santa Casa of Guaratinguetá, allowing the bed’s height adjustment with electromechanical drive. This adaptation aims to introduce improvements in the routine work of nurses and reduce ergonomic problems stemming from repetitive strain during the transfer of patients to stretchers and wheelchairs, as well as providing more comfort to the bedridden patient. The device is mainly composed of: an electric induction motor used to drive the engine, a steel spindle with square thread, which allows axial displacement of the bed, a transmission system with pulleys and belt, which transmits power supplied by the motor to the spindle. The mechanism allows the height of the bed is regulated between 400 and 800 mm. The estimated implementation cost of this proposal is lower than the acquisition cost of a commercial hospital bed with the same features, which confirms the feasibility of the proposed solution

Proposta de um dispositivo para adaptação em uma cama hospitalar para ajuste de altura

In hospitals, health professionals may face different situations and problems. By following them, it is remarkable that one of the difficulties is related to the support provided by the facilities to carry out their work. This also affects the quality of treatment offered to patients. One of the points of improvement that could be studied is hospital beds. The Fawler's simplest hospital bed type, used in most Brazilian public hospitals, is designed with an ergonomic average height that offers a default position for analysis and treatment of patients. There is no possibility of adjusting the height of those beds, and hence there is a limitation in this regard since that height is fixed, but the physical structures of the workers and patients may vary widely and there may be a conflict when there are people too large or small involved in this process. Beyond that, studies by experts show that beds with height adjustment decreases the muscular effort and improve the movement quality of the spine of nursing staff, reducing the force on certain vertebrae and also the ergonomic risk. Of course, patient comfort is also affected accordingly. As the beds made with height adjustment are very expensive, this study aims to design a device to adapt the not adjustable beds. The project must be viable from an economic and mechanic standpoint, being able to adapt both old and new simplest Fawler hospital bed models, since their dimensions are similar. The final result shows that it is possible to adapt such beds using the designed concept at a viable cost. Furthermore, this concept could be applied in other bed types or objects that have hollow feet

Estabilidade oclusal a longo prazo de Classe II, divisão 1, após tratamento com extração de pré-molares

Patients are looking for esthetic and functional changes when seeking orthodontic treatment and expect the remaining of a stable occlusion. Occlusion stability is one of the goals of the orthodontist; however, dental relationships changes in long-term can occur leading to a relapse of the treatment. Teeth and shape of arches tend to return to the original form, been the retention phase important after the appliance removal, even after several years of post-treatment. This article approaches a submission of a clinical case of Class II division 1 treated with extraction of premolars analyzing its long-term stability.

Estudo comparativo da inclinação do plano oclusal de modelos para cirurgia ortognática montados em dois tipos de articuladores semi-ajustáveis

Purpose: The aim of this study was to compare occlusal plane angulation measured in two different types of semi-adjustable articulators with that obtained on the lateral cephalometric radiograph. Materials and Methods: 20 patients due to undergo orthognathic surgery had dental casts mounted in two different types of semi-adjustable articulators through face bow transfer from the position of the maxilla and occlusal recording to the mandible. After mounting, the inclination of the occlusal plane in the articulators was measured and compared with the inclination measured at on both articulators and compared with the inclination measured on the lateral cephalometric radiographs and between the articulators themselves. The results obtained werestatistically analyzed. Results: Mean angulation values for the Bio Art (7.55º) and Kavo (-5.70º) articulators differ by 13.25º, which is statistically significant (p=0.00). When individually compared to the lateral cephalometric radiograph (5.075º), the Bio Art articulator showed more similar angulation values, with a difference of 2.475º, while the Kavo articulator presented a difference of 10.775º. Conclusion: Neither of the models of semi-adjustable articulators accurately reproduced the inclination of the maxillary occlusal plane of patients with dentofacial deformities; the difference between the two articulators tested and the lateral cephalometric radiograph was lower for the Bio Art than for the Kavo articulator.

Matriz oclusal para restauração com resina composta de baixa contração: simplificação eficiência

The composite resin is the material of election for direct restorations in posterior teeth currently. The restorative dentistry aims to improve each day the material and facilitate the restorative technique. This paper describes the technique of occlusal matrix made to speed up and preservation the occlusal surface of a first molar tooth affected by caries lesion. A new resin-based composite was used called Silorane, which may be placed in larger increments due the material has low shrinkage and polymerization stress. The use of occlusal matrix associated with a low shrinkage resin composite can simplify the clinical work, and result in a restoration with excellent reproduction of anatomical.

Influência do material oclusal na distribuição de tensões em próteses implantossuportadas unitárias

Objective: the aim of this study was to evaluate the influence of occlusal veneering material in single fixed implant-supported crowns through the 3-D finite element method. Material and methods: Four models were fabricated using the Rhinoceros 4.0, SolidWorks, and InVesalius softwares. Each model represented a block of mandibular bone with an external hexagon implant of 5 mm x 10 mm and different veneering materials including NiCr (1), porcelain (2), composite resin (3), and acrylic resin (4). An axial load of 200 N and an oblique load of 100 N were applied. Results: model (2) with porcelain veneering presented a lower stress concentration for the NiCr framework, followed by the composite resin and acrylic resin. The stress distribution to the implant and bone tissue was similar for all models. Conclusions: there is no difference of stress distribution to the implant and supporting structures by varying the veneering material of a single implant-supported prosthesis.
