L.2 Development of the Dentition 2 Flashcards
Spacing is good yo: more than 6mm will mean a __% chance of crowding in the permanent dentition
0%
Spacing of __-__mm in the primary dentition yields a 205 chance of crowding in the permanent dentition
3-6mm
Spacing of less than 3mm in the primary dentition yields __% probability of crowding in the permanent arch.
50%
What is the % chance of crowding in the permanent teeth id there is no spacing in the primary teeth? crowding in the primary??
no spacing 66%, crowding 100%!
Where are the two primate spaces?
mesial to the maxillary canine and distal to the mandibular canine
What is the ideal occlusion for primary teeth? What permanent class occlusal relationship will it led to ?
mesial step…class I
an exaggerated mesial step occlusion in primary teeth is most likely to lead to which class occlusion in the permanent occlusion?
class III
a distal step occlusal relationship in primary teeth is most likely to lead to what class permanent occlusal relationship?
class II
What are the ideal overbites and over jets?
2mm for both
When is the greatest spacing for primary teeth?
3-4 years old
Your strong point lol….MIXED DENTITION!!! Early- __-__ years old = incisors and first molars
6-9 years old
Your strong point lol….MIXED DENTITION!!! Late- ___-___ years old = canines, 1st, 2nd PMs
9-12 y/o
SO covering both early and late mixed dentition it is from the ages of ___-___
6-12 yo
ERUPTION FOLLOWS EXFOLIATION BY HOW LONG?
6 months
Enamel of permanent tooth complete about ___ years prior to eruption
3 years
