<p>A dental implant system comprising a foundation fixture (11) to be embedded in the jaw bone; said system further comprising a hollow transmucosal abutment member (20) supporting a keeper for either a single tooth prosthesis or multiple teeth prostheses. The abutment comprises a plurality of inwardly curved resilient members (21) defining a hollow column extending from a series of external threads (23) which connect, in torus-like fashion, to a hollow pedestal section (25) for the abutment. The internal surfaces of the resilient members have configured protrusions (22) configured to interlock with the keeper. This configuration, in a no-load condition, allows the keeper to rest within the foundation fixture at sufficiently spaced-apart relationship between the keeper and the fixture to maintain a shock-absorbing fluid reservoir. An elastic seal (30) is fitted between the keeper base and the pedestal of the abutment for closure of the reservoir.</p> |
