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.

Implication

Retrospective analysis reveals sufficient bone volume for miniscrew insertion in varied populations, implying effective anchorage options.

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.
