Description
Zhizheng Li and colleagues present their 2026 study on how far cone-beam CT placement of impacted lower wisdom teeth drifts from the true position found at surgery. Errors of a few millimeters matter near nerves.
For ten deep cases, printed surgical guides marked the crown edges predicted by scans, and gaps to the real crown were measured in surgery. Sixty more cases gave a horizontal measure only. Real crowns sat forward and lower than scans showed, with mean shifts near five millimeters. Deeper impactions drifted more. Surgeons should leave extra margin when planning cuts in the back jaw.
