Classified in Biology

Written on in English with a size of 4.17 KB

Cranial Synchondroses and Closure Times

Synchondroses are temporary cartilaginous joints crucial for craniofacial growth:

  1. Spheno-occipital: Located between the occipital and sphenoidal base. Closes at 18–20 years old.
  2. Inter-sphenoidal: Located between the anterior and posterior sphenoid. Closes before birth (prenatally).
  3. Spheno-ethmoidal: Located between the sphenoidal and ethmoidal bones. Closes at 5–7 years old.
  4. Intra-occipital: Located inside the occipital bone. Closes at 3–5 years old.

Etiology of Local Malocclusion

Local factors contributing to malocclusion are categorized as Hereditary, Acquired, or Other:

  • Hereditary Manifestations:
    • Skeletal manifestation
    • Soft tissue manifestation
    • Dental manifestations
  • Acquired Factors:
