Intro to Ortho Review

Front

What is the 'E' space in orthodontics?

Back

The 'E' space refers to the mesial distal width difference between the primary 'E' teeth (second primary molars) and their successors, the permanent premolars.

Front

In which arch is the space gained from the 'E' & Leeway Space more significant?

Back

Mandible

Front

What is the definition of leeway space?

Back

The leeway space is the difference in mesiodistal crown widths of the primary canines and molars compared to that of their successors, the permanent canines and premolars.

Front

What are primate spaces?

Back

Primate spaces refer to the space in the primary teeth mesial to the maxillary canine and distal to the mandibular canine.

Front

What is late mesial shift?

Back

Late mesial shift occurs when early exfoliation of the primary secondary molars leads the permanent first molars to shift mesially to utilize the 'leeway space'.

Front

What is the significance of the 'E' space in orthodontics?

Back

The 'E' space is crucial for maintaining space for the eruption of permanent teeth and preventing crowding.

Front

How does early loss of primary molars affect dental alignment?

Back

Early loss can lead to mesial drift of adjacent teeth, potentially causing crowding and misalignment of permanent teeth.

Front

What is the role of a lower lingual holding arch?

Back

A lower lingual holding arch is used to prevent early mesial drift of molars when primary second molars are lost prematurely.

Front

What is the difference between 'E' space and leeway space?

Back

The 'E' space specifically refers to the space related to the primary second molars and their successors, while leeway space encompasses the overall space difference between primary and permanent teeth.

Front

What happens during the mixed dentition period?

Back

During the mixed dentition period, both primary and permanent teeth are present, and significant changes in dental alignment occur.
