What are the 3 components of growth?
What are the 3 planes of growth?
What are the factors of growth?
What are the three variables of growth?
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
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
What do we use to correct a maxillary transverse deficiency?
Spacers/expanders to spread the posterior teeth out
What are the features we look to attain when correcting a maxillary AP deficiency?
Max/mandible in good position
Class I skeletal relationship
Ideal incisor angulation
How long do we have spacing throughout the dentition?
Until 4 years of age
Second molars drift mesially
What is early mesial shift?
Closing of the interproximal space of primary dentition on eruption of first permanent molars
What are the 3 anterior-posterior molar relationships?
What is the incisor eruption path?
From lingual to labial
Increased permanent incisor angulation
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
What are the differences in
permanent and primary incisors and intercanine distance?
Intercanine distance increases by
Primate space may close- Canines relocate
What are the differnces in
permanent incisors and primary? Intercanine distance?
Primate spaces may close
