Abstract Background Keratocystic odontogenic tumor (KCOT) is one of the most common odontogenic neoplasms. There are many kinds of treatment modalities which can be a conservative method, such as enucleation or an aggressive method, such as enucleation followed by cryosurgery and radical surgical tactics with bone resection. In the literature a relatively high recurrence rate reported for KCOT with a range of 5-70 % depending on the method of treatment. Case presentation The aim of this case report is to present the prosthetic rehabilitation of an 18-year-old male patient who had previously been operated on for a KCOT. Enucleation was preferred due to the size of the lesion. Even though a recurrence was observed 1 year postoperatively, a less extensive procedure was sufficient for the treatment. The patient was successfully rehabilitated with an implant after a follow up period of 19 months following the second operation. Conclusion Prosthetic rehabilitation of a single tooth implant after enucleation of KCOT is an optimal treatment option. No temporization was needed due to the patient preferences. After waiting for a 3 month period of healing phase, the gingiva former was fixed. After 1 week an impression was made and the crown was cemented. The restoration was clinically successful in the 3 month, 6 month and 1 year of follow-up.

Introduction The term “odontogenic keratocyst” was introduced in 1956 by Philipsen [10]. Although being previously defined by the World Health Organization (WHO) as a cyst arising in the teeth-bearing areas of the jaws, its rapid growth potential and the propensity to recur gave rise to a controversy about its true pathological nature and terminology. In 2005 it was defined by the WHO as “keratocystic odontogenic tumor” (KCOT) and was described as a benign unicystic or multicystic intraosseous tumor originating from odontogenic epithelial remnants [3, 8, 17] with a characteristic lining of parakeratinized stratified squamous epithelium and an aggressive behavior with propensity to recur. It can be seen as a solitary lesion or multiple lesions which can be a symptom of inherited naevoid basal cell carcinoma syndrome (NBCCS). The orthokeratinizing variant of this tumor is not classified as a
