Understanding Temporomandibular Joint and Disc Displacement

🏥 The temporomandibular joint (TMJ) is a crucial joint responsible for jaw movement.

🔘 The TMJ consists of the condyle of the jaw and the mandibular fossa, with a unique articular disc providing cushioning between the bones.

💪 The jaw is connected to the lateral pterygoid muscle, which plays a role in chewing, and the retrodiscal tissue behind the disc contains blood vessels and nerves.

😮 The opening of the mouth involves rotational movement of the condyle in the first 20mm.

🔑 The temporomandibular joint (TMJ) allows the mouth to open and close.

🔑 The most common TMJ disorder is disc displacement, where the disc moves forward and compresses the retrodiscal tissue.

🔑 When the jaw opens, the condyle jumps over the back of the disc, producing a clicking sound.

💡 Desplazamiento del disco con reducción: el cóndilo permanece detrás del disco y la boca se limita en su apertura.

💡 Desplazamiento del disco sin reducción: la mandíbula queda bloqueada sin poder abrirse ampliamente.

💡 La condición se resuelve por sí misma gracias a la adaptación natural del tejido retrodiscal.
