Periodontal Ligament Design and Function

• 1) Alveolar Crest - retain the tooth in alveolus,
  oppose lateral forces, and protect deeper
  periodontal ligament structures

• 2) Oblique - oppose axially directed forces

• 3) Transseptal - prevent teeth from losing contact

18
Periodontal Ligament Design and Function

• 4) Horizontal - oppose lateral forces

• 5) Interradicular - prevent tooth tipping and
  extrusion

• 6) Apical - prevent tooth
• tipping and extrusion,
• protect vessel and nerve
• supply to the tooth
