Gauge, deflection and aspiration, why breakage happens, where the fragment goes, what to do in the chair, retrieval and prevention.

Anatomy, risk factors, prevention, small vs large fragments, splinting and timing, the sinus, complications and consent.

How the condyle gets stuck in front of the eminence, recognising it, every reduction method, aftercare and recurrent cases.

Symphysis plus both condylar necks: mechanism, the open bite, how much to fix the condyles, approaches, plate lines and children.

Why the clot dissolves, who is at risk, telling it from infection, step-by-step treatment and the prevention evidence.
