Placa miorrelaxante oclusal impressa 3D para controle do bruxismo do sono: relato de caso

RESUMO

O bruxismo é definido como o hábito de ranger, apertar, imobilizar ou projetar a mandíbula, com graves consequências ao sistema estomatognático, como desgaste dentário, dores musculares e articulares. Pode ser classificado em bruxismo do sono (BV) e bruxismo de vigília (BV). Sua etiologia é multifatorial e, para ser controlado, é necessária uma abordagem multidisciplinar. As placas oclusais são utilizadas como terapia de primeira linha para o bruxismo do sono, sendo tradicionalmente confeccionada com acrílico prensado. Com a introdução das ferramentas baseadas na era digital, as placas agora podem ser confeccionadas por sistemas assistidos por manufatura (computer aided design/computer aided manufacturing – CAD/ CAM), seja através de impressões ou por meio de fresagem. O objetivo deste trabalho foi descrever a confecção de uma placa oclusal pelo método híbrido, relatando a sua importância para o controle do bruxismo do sono e consequente alívio dos sinais e sintomas das desordens temporomandibulares.

ABSTRACT

Bruxism is defined as the habit of grinding, clenching, immobilizing, or projecting the jaw, with serious consequences to the stomatognathic system, such as dental wear, muscle, and articular pain. It is classified as sleep bruxism (SD) and wakefulness bruxism (WB). Its aetiology is multifactorial, and multidisciplinary approaches are required for its control. Occlusal splints are used as first-line therapy for sleep bruxism and are traditionally made of pressed acrylic. With the introduction of digitally based tools, these can now be made by computer aided design/computer aided manufacturing (CAD/CAM) systems, either by impressions or by milling. The aim of this paper is to describe the manufacture of an occlusal splint using the hybrid method and to report on its importance for the control of sleep bruxism and consequent relief of signs and symptoms of temporomandibular disorders.

Key words – Bruxism; Occlusal splints; CAD/CAM; 3D printing.
