Supernumerary teeth are extra teeth that need to be extracted. Achieving an efficient, safe and minimally invasive extraction with rapid and precise intraoperative location determination has been a clinical challenge in extracting embedded supernumerary teeth. Advances in imaging, digital technology and materials science could realise the accurate and minimally invasive extraction of such teeth. Based on the patient’s cone beam computed tomography image and computerised 3D modelling, the digital template acts as a ‘bridge’ that helps in the application of a surgical design to the real surgery directly, which could greatly shorten the surgery time, reduce the trauma and decrease the risk. The aim of this review was to summarise the functional realization of the template-guided extraction of embedded supernumerary teeth and the current application of digital guides and explore its future development trend.

Key words: digital template, tooth extraction, embedded supernumerary tooth, location
