Summary:Fracture of the mental spine (genial tubercles, spina mandibularis) is comparatively rare entity of mandibular fracture. It can be assertained only by occlusal radiogram. This type of fracture is considered that normal occlusal stress is a main role, in the severely atrophied edentulous mandible and hypertrophied spines in the denture bearing elders. The pathogenesis of this fracture is proposed as one of the stress or spontaneous fractures, like a so-called pathologic fracture. In this sequence, the dental practitioners should keep in mind the possibility of this fracture, especially in denture construction. The authors reported three further cases treated conservatively and discussed the mechanism and treatment of this injury.
