Description
Placing a dental implant right after pulling a front tooth is delicate, since drills tend to drift toward the thin outer bone. Ahmed Ibrahim Aboul Fettouh and six co-authors ran a clinical trial in 2026 to measure that drift under a new computer-guided drilling method.
Twenty-six patients with failing upper front teeth had implants planned virtually under a safe-angle rule, then placed with partial guidance and a plateau drilling protocol. After three months the team compared the real implant positions with the plan, measuring angle and depth errors at the top and tip. Implants that sit too far outward are known to triple gum recession risk, so small errors matter. The trial also tracked the bone that formed and early appearance outcomes.
