Space Management Flashcards
_______ quantifies the amount of needed space (crowding/ spacing)
within the arches estimating the severity of space discrepancy.
• requires a comparison between the amount of space available
for the alignment of the teeth and the amount of space required to align
them adequately.
•Comparison has 3 results:
• Excess
• OK
• Deficiency
Space analysis
______ is characterized by interdental spaces and lack of contact
points between the teeth.
Spaced dentition
Does spacing occur more in boys or girls?
Boys
Three treatment options are available for generalized spacing:
- Esthetic intervention using composite resin, Veneer, Crowns,…
- Orthodontic space closure.
- Closure of anterior spaces and opening posterior spaces
After orthodontic treatment, it is frequently necessary to apply _______
as these cases have a high risk of relapse.
fixed retention
•The midline diastema is a space (or gap) between the maxillary central
incisors.
•The space can be a normal growth characteristic during the primary and
mixed dentition.
•Prevalence in 10 to 12 years old children:
• More in maxilla. Between central incisors.
• African American 19%
• Caucasians 8%
Diastema
Is spacing more common in causcasians or african americans?
African americans
FOr a child, how do you treat an oversized frenum?
Frenectomy then close space naturally
For a teen or adult, how do you treat frenectomy?
Close the space then frenectomy; scar tissue
Diastemas more than __ mm require active intervention
2 mm
Is crowding caused by a specific factor?
No multifactorial
_______ is the lack of space for all the teeth to fit normally within
the jaws.
•could be as the result of:
• Twisted or displaced teeth.
• Disharmony in the tooth to jaw size relationship.
• Early or late loss of primary teeth
• Improper eruption of teeth.
Crowding
It determines the ratio of the MD widths of the Max teeth to Man teeth.
•It shows whether there is any tooth size discrepancy between the upper and lower teeth.
•It is recommended for permanent dentition, after eruption of all permanent teeth from 1st molar to 1st molar.
•determines:
• Overall ratio.
• Anterior ratio.
Bolton analysis
If the overall ratio is less than 91.3%, it indicates _____ teeth materials excess
Maxillary
If the overall ratio is more than 91.3%, it indicates _____ teeth materials excess
Mandibular
