ABSTRACT
ABSTRACT: In this study, we report the case of a patient presenting a severe atrophic mandible that was treated with short implants and stable internal fixation, without using bone grafts or biomaterials. The patient had a long history of failure of several previous consecutive treatments. Cone-bean tomography revealed a small amount of mandibular bone, suggesting a high risk of fracture of the mandible during drilling and installation of osseointegrated implants. We opted to place 5 implants (4.0 × 7.0 mm) between the mental foramens. Since the mandible presented a high risk of fracture, we inserted a titanium plate (2.3 mm) as bone reinforcement along the entire length of the mandible, including the bilateral mandibular angles. A Branemark type prosthesis was installed 5 days after the procedure. After 24 months, the patient continues to be satisfied and presents good masticatory functions without any complications.

Objetivo: Este trabalho teve como objetivo avaliar a capacidade do laser de baixa potência em reduzir a sensação dolorosa durante a injeção da substância anestésica. Metodologia: Para isso, foram selecionados sessenta pacientes que iriam receber anestesia na região do palato. Esses pacientes foram divididos em três grupos: o grupo I recebeu irradiação com laser de AsGaAl antes da anestesia; o grupo II recebeu irradiação com a luz do fotopolimerizador antes da anestesia (placebo), e o grupo III não recebeu nenhum tratamento. A sensibilidade foi registrada por meio de uma escala visual numérica (EVN). Resultados: Após a análise dos resultados, pôde-se concluir que o laser de baixa potência de Arseniato de Gálio-Alumínio, segundo protocolo utilizado, promoveu uma redução da dor resultante da aplicação do anestésico na região do palato, quando utilizado previamente ao ato anestésico.
Porpuse: The aim of this study was to evaluate the low level laser capacity in reducing the pain during the anesthetic injection. Metodology: Sixty patient that would receive anesthesia in palate area were selected. Those were divided in three groups: the group I received irradiation with Gallium/Aluminium/Arsenide (GaAlAs) laser before the anesthesia, the group II received irradiation with the light curing unit device before the anesthesia (placebo) and the group III didn't receive treatment. The sensibility was registered through a numeric visual scale (NVS). Results: After the analysis of the results it can be ended that the GaAlAs low level laser, according the parameters used, promoted a pain reduction resulting from the anesthetic application in palate area, when previously used to the anesthetic action.
