Introduction :
Cemento-Osseous Dysplasia is a benign fibro-osseous lesion affecting mainly African / African American female patients aged between 40 and 50 (1).
COD is classified into 3 categories according to its location;
Radiologically, the lesion is radiolucent at first but becomes progressively opaque as it matures with the deposition of a cementum-like non-vascularized tissue (3). For this reason, elective surgery such as periodontal surgery, extractions or implant placement is contraindicated (4).
In this case report, we will present a successful implant rehabilitation of a posterior mandibular edentulism in a patient presenting focal COD using a modified protocol.
