Abstract(s)
O articulador é um dispositivo mecânico que simula as articulações temporomandibulares, a mandíbula e a maxila. Os modelos superiores e inferiores das arcadas dentárias do paciente são montados neste dispositivo para simular alguns ou todos os movimentos mandibulares.
Devido à impossibilidade de o paciente estar presente em todas as fases do estudo (diagnóstico, planeamento e execução laboratorial dos trabalhos), os articuladores foram criados com o objetivo de auxiliar os profissionais na pesquisa, no estudo, na análise funcional das relações estáticas e dinâmica, na oclusão dentária, na articulação temporomandibular e na confeção de próteses dentárias dentro da complexidade do aparelho estomatognático.
Vários modelos de articuladores foram criados para estas finalidades, sendo que esta variedade de modelos torna possível a seleção de um instrumento que satisfaça, dentro de limitações específicas, as necessidades clínicas de cada caso.
Com a atual tendência para medicina dentária digital, o “digital clinician” deve perceber como implementar e manusear um articulador digital na prática diária.
No campo da medicina dentária reabilitadora e restauradora, o articulador digital apresenta aplicações da realidade virtual no mundo da prática clínica para a análise do complexo estático e dinâmico das relações oclusais.
O articulador virtual tem a capacidade de simular movimentos específicos de mastigação do paciente. O programa prevê os locais onde os dentes oponentes vão estar em contato. É de referir que, sem os dados específicos do paciente inseridos no programa, um articulador digital vai ter o mesmo comportamento que um articulador tradicional.
Estudos feitos para verificar a veracidade do articulador virtual apresentam correspondência positiva na simulação do número e posições dos contactos dinâmicos dos dentes. É um instrumento preciso para a análise da oclusão em pacientes, podendo ajudar o profissional a estabelecer um diagnóstico e planear a melhor opção de tratamento.

Several articulator models have been created for these purposes, and this variety of models makes it possible to select an instrument that meets, within specific limitations, the clinical needs of each case. With the current trend towards digital dental medicine, the "digital clinician" should understand how to implement and handle a digital articulator in its daily practice. In the field of rehabilitative and restorative dental medicine, the digital articulator presents applications of virtual reality in the world of clinical practice for the analysis of the static and dynamic complex of occlusal relationships. The virtual articulator can simulate specific mastication movements of the patient. The program predicts the locations where the opposing teeth will be in contact. It should be noted that without the specific patient data inserted in the program, a digital articulator will have the same behavior as a traditional articulator. Several studies to verify the veracity of the virtual articulator show positive correspondence in the simulation of the number and positions of dynamic contacts of teeth. It is an accurate instrument for occlusion analysis in patients and can help the professional establish a diagnosis and plan the best treatment option.
