Summary

This small, completed study looked at whether ultrasound can help check the bone around dental implants as well as cone-beam CT scans do. Researchers measured bone thickness and height in 4 patients using both methods and compared them to photos taken during surgery. The goal was to see if ultrasound could provide extra information without the drawbacks of CT scans, like image artifacts.
