Many patients seeking dental care wish to improve facial and smile aesthetics to be accepted in modern day society. In denture wearers, the physiological resorption causes atrophy mainly in the maxilla, being necessary to carry out reconstruction techniques and sometimes orthognathic surgery to improve occlusal stability and facial harmony. The aim of this study is to discuss the features related to the rehabilitation of edentulous patients with indication for reconstruction of the maxilla using bone grafts and orthognathic surgery by means of a clinical case. In the present case, after the prosthetic rehabilitation, the patient was full satisfied with obtained results and dismissed the initially proposed surgical protocol. Therefore, professionals should provide therapeutic options but the patient’s opinion should prevail provided its clinical feasibility.

A large number of metal alloys are used in Dentistry for the manufacture of fixed and removable dentures. In the oral cavity, these structures are exposed to a chemically aggressive medium, like saliva and mechanical efforts, like mastication. In addition, acidic solutions containing fluoride ions are also frequently used in dental treatments to prevent dental plates and decays development. In this context, it was considered important to investigate the influence that a fourth element could exert when added to the ternary alloy Ni-Cr-Mo, largely used in Brazil. Therefore, electrochemical tests were done to evaluate the resistance to corrosion of quaternary alloy 65Ni-25Cr-5Mo-5Ta and 65Ni-25Cr-5Mo-5W in NaF solution 0,08mol / L, pH = 4.7. For greater understanding the microstructure and morphology of alloys were studied, through metallographic analysis, using optics microscopy and electron microscopy scanning. For the electrochemical tests were applied techniques traditionally used in corrosion researches, such as: potential measures in open circuit (OCP) and cyclic polarization (CP). It was found that both quaternary alloys showed very similar results. Comparing these quaternary alloys with the ternary 65Ni-25Cr-10Mo, it was found that the quaternary alloys exhibit greater resistance to corrosion, in other words, less passivation current density than the ternary alloy, showing that it is advantageous to add a fourth element in the alloy

The main objective of this paper was to discuss the importance of the reverse planning as guidance to surgical procedures on immediate loading implant-retained prosthesis, presenting a case report. Such design aims to define anchorage orientation after determination of prosthetic design. This is quite important because the possibility of success of cases with this kind of planning may achieve high levels of satisfaction. Another important aspect is the possibility of fast and definitive restoration of patients’ function and aesthetics

INTRODUÇÃO: O governo brasileiro atualmente credencia cerca de 140 centros especializados para adaptações de aparelhos de amplificação sonora individual via SUS. Adaptações à distância através da internet podem permitir maior eficiência na prestação deste serviço e com maiores chances de aceitação por parte do paciente do SUS. OBJETIVOS: Descrever o caso de adaptação à distância realizado entre duas cidades, com revisão da literatura. MÉTODO: Equipamentos de informática e de tecnologia da informação, programador universal, aparelhos de amplificação sonora individual. ESTUDO DE CASO: Uma fonoaudióloga lotada num centro especializado introduziu a um centro remoto (distância de 200 km) um novo aparelho de amplificação sonora individual e seu programa de adaptação. O centro remoto assistiu a adaptação de dois pacientes em sua clínica, realizando voluntariamente a adaptação do terceiro paciente. Todo o procedimento foi realizado através da internet, contando com recursos de áudio e vídeo em todos os procedimentos. RESULTADOS: Três pacientes foram adaptados à distância. Três fonoaudiólogas receberam treinamento à distância de como adaptar aparelhos auditivos. CONCLUSÃO: Foi possível adaptar AASI à distância, além de prover treinamento e habilitar um centro remoto na adaptação de um novo aparelho de amplificação sonora individual e de seu programa de adaptação. Tal procedimento pode ser útil ao governo na condução de políticas públicas da saúde auditiva.
