Favourable and Unfavourable Fracture Classification of fractures: W hen viewed from side: Horizontally Favourable Horizontally Unfavourable When viewed from oclusal surface: Vertically Favourable Vertically Unfavourable W hen viewed from side 1.Horizontally Favourable. Line starts at alveolar margin and extends forwards or anteriorly and downwards till lowest border of mandible. The horizontal direction of fracture line favours the unopposed action of masseter n medial pterygoid muscle in an upward direction. The depressor n elevator act in different direction. 2.Horizontally unfavourable. Fracture line starts at alveolar margin and extends backwards and posteriorly till lowest border of mandible. Fracture line starts at alveolar margin and extends forwards or anteriorly and downwards till lowest border of mandible.
