Abstract:

Cemento-osseous dysplasia (COD) is a relatively common fibro-osseous lesion that occurs in the tooth-bea-ring areas of the jaw, occasionally found in the alveolar bone of edentulous areas, posing challenges for the selection and design of implant treatments. Radiological examinations are crucial for the diagnosis of COD and are the main means of follow-up. This paper summarizes the clinical, radiographic, and pathological features of COD and analyzes reported ca-ses of successful and failed implants, suggesting that COD is usually not a contraindication for dental implantation. On the basis of these analyses, treatment recommendations for implantation in this specific condition are proposed to increase the success rate of implant treatments of patients with COD.

Key words: cemento-osseous dysplasia, dental implantation, radiological examination, treatment recommendation
