Abstract: The odontogenic keratocyst (OKC) is the third most common cyst of the jaw. OKCs are benign developmental cysts that are often locally destructive and large at presentation. They are usually identified during radiographic examination and require appropriate treatment planning to ensure optimal care. We present a very challenging case of a 12-year-old boy with a large mandibular OKC. The roots of several teeth were displaced, with both LR3 and LR5 unerupted and severely malpositioned. A multidisciplinary approach was therefore essential in view of the complexity, with joint planning and close liaison of treatment between the surgeon, orthodontist and general dental practitioner (GDP). This was fundamental to ensure the best possible outcome was achieved for the patient.

Clinical relevance: This case report aims to increase awareness of OKCs to GDPs and outlines the surgical, orthodontic and restorative challenges faced in the management of such cases.

During this webinar Eoin O’Sullivan will take you through his personal journey with digital scanning, explaining how he found himself in a dilemma when he had to replace his first iTero, after he had assumed that the scanner’s capabilities would transition to focus on orthodontics when it was bought out by Align Technology in March 2011. He will share his thoughts about which scanner would best suit his restorative practice, and why he opted for the next generation of iTero over all the other scanners on the market.
