**Core Concept**
A fracture mandible requires immobilization to allow for healing of the bone and surrounding tissues. The duration of immobilization is crucial to prevent malunion, nonunion, or other complications.

**Why the Correct Answer is Right**
The American Association of Oral and Maxillofacial Surgeons recommends immobilization of mandible fractures for 4-6 weeks. This duration allows for sufficient time for the bone to heal and the surrounding tissues to recover. Immobilization with a splint or a maxillomandibular fixation (MMF) is typically used to maintain the fracture site in proper alignment.

**Why Each Wrong Option is Incorrect**
**Option A:** This duration is too short and may lead to malunion or nonunion of the fracture.
**Option B:** This duration is too long and may result in unnecessary prolonged immobilization and its associated complications.

**Clinical Pearl / High-Yield Fact**
A general rule of thumb for immobilization of mandible fractures is to immobilize for 4-6 weeks, with the specific duration depending on the location and severity of the fracture.

**Correct Answer: C. 4-6 weeks.**
