After the loss of natural teeth, bony changes in  the jaws begin to take place immediately. Because the alveolar bone no longer responds to – stresses placed in this area’ by the teeth. and period on talligament, bone begins to resorb. The specific pattern of resorption is unpredictable in a given patient
because great variation exists among Indtviduals. In many patients this resorption process tends to stabilize after a period, whereas in others a continuation of the process eventually ·results in total loss of alveolar bone
a!’ld underlying bas al bone (Fig. 13-1). The results of this resorption are accelerated by wearing dentures and tend to affect the mandible more severely than the maxilla because of the decreased surface area and less favorable distribution of occlusal forces (see Fig: 13-1).1
