DISCUSSION

ADVANTAGES OF PROSTHETIC REHABILITATION IN
MANDIBULAR FRACTURES
While the initial management of mandibular fractures primarily
involves reduction and fixation (surgical or non-surgical),
prosthetic rehabilitation plays a crucial role in addressing
residual functional and aesthetic deficits—particularly in cases
involving malocclusion, malunion, or significant tooth loss.
The advantages of prosthetic rehabilitation include:
• Restoration of Occlusal Function: Prostheses such as crowns,
bridges, or removable partial dentures can re-establish
proper intercuspation and occlusal vertical dimension.
Studies have shown that a stable and functional occlusion is
critical for efficient mastication, with improvements in bite
