A female with achondroplasia will reach an average adult height of about 4 feet, 1 inch. 3 Avera - tion (Figure 1). Skeletal aging is characterized as a gradual loss of bone mass due to an excess of bone resorption that is not matched by new bone formation. There are two major types of bone Department of Orthodontics. . . UNIT . A4. Theories of Craniofacial Growth. Introduction. Growth is influenced by genetics, environment, nutrition, physical activity, health, illness and similar factors.. Normally, there exists a balance between bone formation & the bone resorption. In osteoporosis, . The rate of bone resorption exceeds the rate of bone formation rendering the bone weak and brittle with loss of bone mass resulting in the reduction of bone mineral density (BMD) due to the deficiency of Vitamin D & calcium..
