Description
Khulood Ali Al-Taezi and co-authors chart the hidden hollow at the back of the lower jaw, a curve that can endanger dental implants. Using cone-beam scans from 406 adults, they sorted the jaw ridge into three shapes: undercut, parallel, and convex. They then measured the lingual concavity, the inward dip on the tongue side, against sex and tooth loss.
The undercut shape was by far the most common, at about sixty-four percent, and it clustered at the second molars. The convex shape grew more likely the longer a tooth had been gone. Men showed larger ridges and larger concavities across many measures. The dip most often sat at or above the level of the jaw's nerve canal. The authors say these patterns should guide implant planning tooth by tooth.
