Examples of topographic relationships to the mandible border. From left to right: Figure 2A represents a defect continuous to the mandibular border with clear discontinuity of mandible cortex, Figure 2B represents a defect continuous to the mandibular border without discontinuity of mandible cortex, Figure 2C exhibits a defect continuous to the mandible base; Figure 2D shows a defect distant from the mandible base.
