Previous issue date: 2014-11-06 / Objective: This parallel RCT compared the efficacy of a CAD/CAM versus a conventional stabilization splint in patients with TMD.
Materials and Methods: 48 age-matched TMD patients from the Ludwig Maximilian University, Munich (LMU), Prosthodontic Department were randomly allocated into groups I (CAD/CAM splint) and II (conventional splint). The RDC/TMD was used for TMD Axis I (groups I, II and III) and Axis II (chronic pain grade - CPG) diagnoses. Numerical Scales (10 cm TMD/NS) were used to measure headaches, face pain, jaw joint pain, jaw joint noises, mastication pain, neck pain, face tension, limitation of mouth opening, complaints during mastication, and teeth sensitivity at baseline and then monthly during 9 months (T1 to T10). Optical axiography was used to measure both right and left condyle movements (mm) at baseline, at 3 months, and at 6 months (T1 to T3).
Results: 32 patients (drop-out rate=33%, 68.75% women, 28.51 ? 7.13 years old), or 16 per group, completed the study. RDC/TMD Axis I showed the following diagnoses: a) 93.75% muscle disorders, b) 37.75% disk displacement with reduction, c) 3.12% disk displacement without reduction, and d) 56.25% arthralgia. There was a significant reduction in 10 of the 13 items of the TMD/NS scales in the CAD/CAM splint versus 8 items in the conventional splint. However, no significant improvement in mandibular movements (i.e., increase in range of motion) and reduction in asymmetry between right and left condyles was observed.
Conclusion: Both treatments were equally efficacious and no difference was found between them. / Objetivo: Este ensaio cl?nico randomizado (RCT) paralelo comparou a efic?cia de uma placa CAD/CAM versus uma placa convencional de estabiliza??o em pacientes com desordem t?mporomandibular (TMD). Materiais e M?todos: 48 pacientes com DTM pareados por idade do Departamento de Pr?tese da Universidade Ludwig Maximilian (LMU), Munique, foram alocados aleatoriamente nos grupos I (placa CAD/CAM) e II (placa convencional). O RDC/TMD foi utilizado para os diagn?sticos de TMD Eixo I (grupos I, II e III) e Eixo II (grau de dor cr?nica CPG). Escalas num?ricas (10 cm TMD/NS) foram utilizadas para medir dor de cabe?a, dor facial, dor na ATM, ru?dos em ATM, dor a mastiga??o, dor no pesco?o, tens?o facial, limita??o de abertura bucal, reclama??es durante a mastiga??o e sensibilidade dent?ria antes do tratamento e ent?o mensalmente durante 9 meses (T1 a T10). Axiografia ?ptica foi utilizada para medir movimentos (mm) condilares direito e esquerdo durante a abertura maximal bucal antes do tratamento, em 3 meses e em 6 meses (T1 a T3). Resultados: 32 pacientes (taxa de drop-out = 33%, 68.75 mulheres, 28.51?7.13 anos de idade), 16 por grupo, conclu?ram o estudo. O Eixo I RDC/TMD mostrou os seguintes diagn?sticos: a) 93.75% desordens musculares, b) 37.75% deslocamento de disco com redu??o, 3.12% deslocamento de disco sem redu??o, e d) 56.25% artralgia. Houve uma redu??o significativa em 10 dos 13 itens nas TMD/NS no grupo placa CAD/CAM versus 8 itens no grupo placa convencional. Entretanto, n?o houve aumento significativo nos movimentos mandibulares (aumento na extens?o do movimento) e assim como n?o foi observado redu??o na assimetria de movimento entre c?ndilos direito e esquerdo. Conclus?o: Ambos os tratamentos foram igualmente eficazes e n?o houve diferen?a encontrada entre eles.
