Aspects of Occlusion

  1. Occlusion
    • The relationship between maxillary and mandibular, when teeth are closed together in a static position. It is also about the adjacent relationship. 
    • Normal Relationship: Molar relationship: Mesiobuccal cusp of maxillary first perm molar occludes with the mesiobuccal groove of the mandibular first molar.
    •    Canine relationship: upper max canine sits in-between the mandibular canine and first premolar.
  2. Overbite
    situation in which the maxillary incisors overlap mandibular incisors.
  3. Overjet
    • (Class III)
    • Situation in which the maxillary dental arch overhangs the mandibular facially.
  4. Proclined
    • (class II) 
    • The condition of being inclined forward proclamation of the upper and lower incisors.
  5. Retroclined
    • (Class II, Division II)
    • Bite is deep and the upper front teeth are retroclined.
  6. Crowding
    Lack of room in the jaw for fall dentition to fit in normal alignment.
  7. Unilateral & Bilateral
    • Unilateral: effects only one side of the mouth- type of cross bite
    • Bilateral: Both sides
  8. Cross-bite
    Type of malocclusion in which mandibular tooth or teeth are placed facially to the maxillary teeth.
  9. Open Bite
    Lack of occlusion of the front teeth when jaw is closed normally (10-30%)
  10. Deep Bite
    Causes teeth line up improperly. Maxillary teeth overlap mandibular teeth and lower teeth make contact with gingiva tissue in upper arch.
