Conclusion :
Placing an implant in a site with COD comes with a high risk on
infection. Patients must be informed of all the therapeutic options and
a consent form must be signed beforehand.
If implant rehabilitation is requested, our main concern is to minimize
the risk of infection especially during and after the drilling sequence.
The three-stage protocol described in this paper proved to be successful
in terms of preventing contamination of the implant surface even when
infection occurs. Further clnical and histological studies must be
carried out to further assess the benefits of this protocol.
