Abstract
Abstract Mastication force dampening dental implant has a cylindrical casing adapted to be implanted in a jawbone. A resilient insert is mounted in the casing and has a first shaftway. A nut is anchored in the insert coaxially with the first shaftway. A threaded shaft is mounted in the first shaftway, the shaft being threaded into the nut. The shaft has a second shaftway in its top portion. A head is fixedly connected to the first shaft at the top of the casing. A tooth or denture retention post is mounted on the head. The retention post is removably mounted in the top of the second shaftway.
