Delayed eruption, malocclusion, poor oral hygiene, and formation of follicular cysts are some complications associated with an impacted supernumerary tooth (ST). Although surgical extraction is one of the methods to prevent these complications, it can also lead to fractured roots or has a risk of permanent injury to young teeth and gingiva. Recently, computer-assisted preoperative simulation has been helpful in planning the surgery for precise extraction of impacted ST guided with 3-dimensional images. Herein, we present 2 cases of extraction of severely impacted ST guided by preoperative computer-assisted simulation and intraoperative augmented reality. While being minimally invasive, the augmented reality-guided system can precisely highlight the tooth position. The therapeutic aspects of these procedures have also been discussed.
