Understanding Temporomandibular Joint and Disc Displacement
This video explains the temporomandibular joint and disc displacement, the most common alteration of the joint that can cause pain and clicking sounds during jaw movement.
00:00:03 ATM - Temporomandibular Joint and Disc Displacement. The joint responsible for jaw movement, consisting of the mandible and temporal bone, with a flexible disc providing cushioning between the bones.
🏥 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.
00:01:10 This video explains the temporomandibular joint and disc displacement, the most common alteration of the joint that can cause pain and clicking sounds during jaw movement.
🔑 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.
00:02:15 This video discusses temporomandibular joint dysfunction and disc displacement. It explains the stages of the condition and how it can be resolved naturally over time.
💡 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.
