Entfernung eines in die Weichgewebe luxierten Zahnkeimes

The displacement of the tooth into the adjacent soft tissue is a possible complication of a germectomy. This poster describes the management of a maxillary third molar germ that was forced into the retromolar aspect of the pterygomandibular space. Conventional radiographic techniques were inadequate in precisely locating the tooth. So we used a CT scan for its visualization and for the planning of the most careful access performing a virtual surgery. This plan was transferred into the intraoperative situs by the use of a maxillary splint added with CT-markers. Finally the tooth could be removed very simple and the adjacent soft tissue could be saved perfectly by using intraoperative navigation.
