Age Related Changes In Mandible

Age Related Changes In Mandible

Write about age changes and clinical considerations of the mandible.
Answer:

Age changes:

1. In infants and children:

1. Two halves of mandible – fuses during 1st year of life.
2. Mental foramen – opens below the sockets for the two deciduous molar teeth.
3. Mandibular canal – runs near the lower border.
4. Angle-obtuse (140 degrees).
5. Coronoid process – large and projects upwards.

2. In adults:

• Mental foramen – opens midway between the upper and lower borders.
• Mandibular canal – runs parallel to the mylohyoid line.
• Angle – 110 or 120 degrees.
• Ramus – almost vertical.

3. In old age:

• Alveolar border- absorbed as teeth fall out.
• Height of body of mandible – reduced
• Mental foramen – close to the alveolar border.
• Mandibular canal – close to the alveolar border
• Angle – obtuse (140 degrees)
• Ramus – oblique.

Clinical Considerations:

• Commonly fracture site is a canine socket as it is weak.
• The next common fracture of the mandible occurs at the angle and neck of the mandible.
• Bone is resorbed on the side of pressure and apposed on the side of tension.
• On the pressure side, there is an increase in the level of cAMP in cells.
• At sites of tension, osteoblasts are activated to produce osteoid which mineralizes to form bone.
• During the healing of fractures or extraction wounds, an embryonic type of bone is formed which is replaced by mature bone.
