Key Points

This research aims to evaluate the available bone volume in the infrazygomatic crest for miniscrew insertion.
Conducted a retrospective analysis using cone-beam computed tomography (CBCT) imaging.
Measured the sagittal dimension of the infrazygomatic crest across different age groups.
Examined potential variations based on sex and side.
Identified sufficient bone volume at a 45° angle for effective miniscrew insertion.
Found no variations based on sex or side, except for older patients having a greater sagittal dimension on the right.
Established the relevance of age in the context of bone availability.

Abstract

Sufficient IZC bone volume is available at an angle of 45° for inserting a temporary skeletal anchorage device, with no sex or side variation, except for the significantly greater sagittal dimension of the right IZC in older patients.
