Purpose: To study the morphology of temporomandibular joint (TMJ) elements and examin bility of a novel biofidelic articular disc casting technique. Methods: 18 formalin-fixed cadavers (77.8% female, 22.2% male) with mean (SD) death age o years were used for this study. In each specimen the masseter muscle, mandibular ramus, a disc were dissected bilaterally and measured for length, width, and thickness. All anatom

ESTUDIO Estudiaron la morfología de los elementos de la articulación temporomandibular (ATM) y examinar la factibilidad de una novedosa técnica de moldeado de disco articular biofidélico. Métodos: se utilizaron 18 cadáveres fijados con formalina (77,8% de mujeres, 22,2% de hombres) con una edad media (DE) de muerte de 71,9 (13,7) años para este estudio. En cada espécimen, el músculo masetero, la rama mandibular y el disco articular se disecaron bilateralmente y se midieron en cuanto a longitud, anchura y grosor.
