The average leeway space in the maxilla (both right and left sides) is
1. 1.8 mm
2. 2.7 mm
3. 3.6 mm
4. 0.9mm
Pedodontics
Answer: 1
The average leeway space in the maxilla (both right and left sides) is 1.8
mm.
Leeway space is the amount of space available for the movement of teeth in the
maxilla and mandible during orthodontic treatment. It is calculated by
subtracting the combined mesiodistal width of the mandibular incisors from that
of the maxillary incisors. This space is crucial in determining the potential
for tooth movement, particularly in cases where there is crowding. The answer of
1.8 mm is a commonly accepted average value in the field of orthodontics.
