The aim of this chapter is to review current knowledge concerning the physiological modifications that occur in the various components of the dentofacial complex from late adolescence through the sixth and seventh decades of life. The physiologic craniofacial changes due to aging can be divided into three categories: skeletal, occlusal and soft tissue. With regard to skeletal changes, female subjects present with an elongation of the skeletal anterior component of the face (2 to 3 mm) in association with an increase in the skeletal retrusion of the midface (1.5 mm). In male subjects, this same modification in the midface is associated with advancement at Pogonion (2 mm). Both genders experience a reduction in arch depth of both dental arches (1.5 mm) associated with a reduction in arch perimeter of both arches (2 to 3 mm) from late adolescence through late adulthood. In the associated soft tissue, both genders show a retrusion (1.5 to 3 mm) and elongation of the upper lip (3 to 4 mm) along with a reduction in the thickness of both upper and lower lips. A significant “droop” of the tip of the nose (3 to 4 mm) also can be observed. During aging, male subjects present with advancement of soft tissue Pogonion (3 mm). Along with the changes in the facial profile, the gingival tissue of the upper incisors shows a recession tendency. Based on information now available about the physiologic changes in the hard and soft dentofacial tissues from late adolescence through late adulthood, we can derive valuable recommendations in order to treat patients orthodontically, orthopedically and surgically, keeping in mind the perspective of the natural modifications due to aging.

Abstract

The aim of this chapter is to review current knowledge concerning the physiological modifications that occur in the various components of the dentofacial complex from late adolescence through the sixth and seventh decades of life. The physiologic craniofacial changes due to aging can be divided into three categories: skeletal, occlusal and soft tissue. With regard to skeletal changes, female subjects present with an elongation of the skeletal anterior component of the face (2 to 3 mm) in association with an increase in the skeletal retrusion of the midface (1.5 mm). In male subjects, this same modification in the midface is associated with advancement at Pogonion (2 mm). Both genders experience a reduction in arch depth of both dental arches (1.5 mm) associated with a reduction in arch perimeter of both arches (2 to 3 mm) from late adolescence through late adulthood. In the associated soft tissue, both genders show a retrusion (1.5 to 3 mm) and elongation of the upper lip (3 to 4 mm) along with a reduction in the thickness of both upper and lower lips. A significant “droop” of the tip of the nose (3 to 4 mm) also can be observed. During aging, male subjects present with advancement of soft tissue Pogonion (3 mm). Along with the changes in the facial profile, the gingival tissue of the upper incisors shows a recession tendency. Based on information now available about the physiologic changes in the hard and soft dentofacial tissues from late adolescence through late adulthood, we can derive valuable recommendations in order to treat patients orthodontically, orthopedically and surgically, keeping in mind the perspective of the natural modifications due to aging.
