What is mandible Malunion?
Malunion is defined as bone healing of a non-reduced fracture. This is possible because a perfect reduction is not necessary for bony union to occur. It normally occurs as a consequence of inadequate reduction and/or fixation, or no treatment at all.
What is mandible symphysis?
The mandibular symphysis is the line of fusion of the lateral halves of the body of the mandible which splits inferiorly to form the mental protuberance. It may serve as a source for bone grafting.
What is the symphysis?

What is the function of the symphysis menti?
Symphysis Menti a.k.a. Mandibular Symphysis is a slight median rim which is located at the external surface of the body of mandible. The line which shows the fusion that appears at the age of 2 years of the two halves of the mandible is indicated by symphysis menti. The point of chin is created by symphysis menti;
Is the mental tubercle of the mandible a true symphysis?
It is not a true symphysis as there is no cartilage between the two sides of the mandible. This ridge divides below and encloses a triangular eminence, the mental protuberance, the base of which is depressed in the center but raised on either side to form the mental tubercle.
Do carnivores have a strong or weak mandibular symphysis?
Solitary mammalian carnivores that rely on a powerful canine bite to subdue their prey have a strong mandibular symphysis, while pack hunters delivering shallow bites have a weaker one. When filter feeding, the baleen whales, of the suborder Mysticeti, can dynamically expand their oral cavity in order to accommodate enormous volumes of sea water.
