Navigation-guided autotransplantation: A novel technique for precise and predictable tooth placement

Year: 2025

Type: article

Abstract: Autotransplantation (AT) is a promising alternative for restoring failed teeth. However, the success rate varies due to technique sensitivity and absence of standardized protocol. We present the first documented AT protocol utilizing a dynamic navigation system, including three core innovations: (1) navigation-guided socket preparation, (2) extra-alveolar retrograde filling, and (3) digital lingual stent fixation with flowable resin. A 55-year-old Taiwanese female with a vertical root fracture in tooth 36 underwent dynamic navigation-guided AT of tooth 38. The recipient area was prepared using a 2.5 mm wide round bur under the X-Guide® navigation. The X-Mark® probe was used to detect underprepared areas, and once preparation was deemed optimal, a three-dimensional (3D) replica was used for final confirmation. Tooth 38 was extracted and underwent retrograde filling, then transplanted into the socket of tooth 36 and fixed with a lingual stent. Postoperative image demonstrated ideal tooth positioning and favorable bone remodeling.
