  1. What are the 3 components of growth?
    • Facial
    • Skeletal
    • Dental
  2. What are the 3 planes of growth?
    • Anterior-Posterior
    • Transverse
    • Vertical
  3. What are the factors of growth?
    • Space/Crowding
    • Alignment
    • Tooth Mass
  4. What are the three variables of growth?
    • Growth
    • Cooperation
    • Interdisciplinary
  5. What are the 4 categories that we need to consider with occlusal and cephalometric analysis?
    • 1. maxilla Vs. mandible
    • 2. Skeletal Vs. Dental
    • 3. Overgrowth Vs. Undergrowth
    • 4. Vertical vs. Horizontal (AP) vs. Transverse
  6. What is a maxillary transverse deficiency?
    • When teeth do not sit outside of the teeth in the mandibular arch
    • Caused by a descrepancy in growth
  7. What do we use to correct a maxillary transverse deficiency?
    Spacers/expanders to spread the posterior teeth out
  8. What are the features we look to attain when correcting a maxillary AP deficiency?
    • Max/mandible in good position
    • Class I skeletal relationship
    • Mesofacial pattern
    • Ideal incisor angulation
  9. How long do we have spacing throughout the dentition?
    • Until 4 years of age
    • Second molars drift mesially
  10. What is early mesial shift?
    Closing of the interproximal space of primary dentition on eruption of first permanent molars
  11. What are the 3 anterior-posterior molar relationships?
    Image Upload 1
  12. What is the incisor eruption path?
    • From lingual to labial
    • Increased permanent incisor angulationImage Upload 2
  13. What are some problems that we encounter with erupting incisor alignment?
    • Poor predictive relationsihp between sizes of primary and permanent teeth
    • mandibular and maxillary loss of primate spcae
    • Mandible: transitional crowding
    • Maxilla: diastema
  14. What are the differences in mandibular permanent and primary incisors and intercanine distance?
    • Permanent 6mm larger than primary
    • Intercanine distance increases by 2-3mm
    • Primate space may close- Canines relocate distolabially
  15. What are the differnces in maxillary permanent incisors and primary? Intercanine distance?
    • Maxillary permanent 7.6mm larger than primary
    • Primate spaces may close
    • Intercanine distance increases 4mm
