Final answer:
Traumatic intrusion is when a tooth is forcefully pushed into the jawbone, as opposed to extrusion, avulsion, or fracture which are different types of dental injuries.
Step-by-step explanation:
Traumatic intrusion occurs when the injured tooth has been forcibly pushed into the alveolar bone, typically as a result of an impact. When a tooth experiences intrusion, it is driven into the jawbone, which can lead to significant damage to the tooth's structure and surrounding tissues. It's important not to confuse this with extrusion (where the tooth is partially dislodged from the bone), avulsion (complete displacement of the tooth from its socket), or fracture (where the tooth or bone is cracked or broken).
