Answer: 3
In children, the healing process for fractures is faster due to the high vascularity and rapid bone turnover in growing tissues. Mandibular fractures in children are typically immobilized for a shorter duration compared to adults, as prolonged immobilization can interfere with the growth of the jaw. Immobilization for 3-4 weeks is generally sufficient to allow proper healing without compromising growth.
