Final answer:
The average leeway space on the maxilla can vary, but newer research suggests it can be as much as 8 diameters side-to-side and 15 diameters deep.
Step-by-step explanation:
The leeway space on the maxilla, which is the upper jaw bone, can vary. The old rule of thumb used to be 5 side-to-side and 7-8 deep. However, newer research suggests that the average leeway space can be as much as 8 diameters side-to-side and 15 diameters deep.
The question pertains to the amount of leeway space per side in the maxilla, especially as it relates to orthodontics or dental anatomy. Traditionally, the rule of thumb for orthodontic leeway space was considered to be approximately 5 diameters side-to-side and 7-8 diameters deep on the maxilla. However, more recent research suggests that a greater leeway space may be necessary, proposing up to 8 diameters side-to-side and as much as 15 diameters deep to provide adequate room for proper dental alignment.
