Die digitale Volumentomografie (DVT) hat seit ihrer Einführung 1998 weite Verbreitung in der Zahn–, Mund–, und Kieferheilkunde gefunden. In Bereichen der Oralchirurgie und Implantologie gehört sie bereits zum etablierten Standard der 3–D–Bildgebung. Vorteile dieser Technologie sind die vergleichsweise geringe Strahlenbelastung sowie die hohe Auflösung in allen 3 Raumrichtungen. Die Anwendung in der Parodontologie ist bisher auf Ausnahmeindikationen beschränkt. Der folgende Artikel stellt aktuelle Studienergebnisse in der Literatur vor und setzt sich kritisch mit diesen sowie mit klinischen Erfahrungen auseinander. Dabei zeigen sich Hinweise auf eine erfolgreiche Anwendung dieser Röntgentechnologie in der Parodontologie. Insbesondere die Klassifikation von Furkationsdefekten im Molarenbereich, das Beurteilen von intraossären Defekten sowie die Detektion von Paro–Endo–Läsionen wird durch die DVT erleichtert.
Since introduction of cone beam computed tomography (CBCT) in 1998, a widespread appliance in dentistry has occurred. This method is already well established in oral surgery and implantology. The advantage of CBCT is the significantly lower effective radiation dose compared with conventional computed tomography and undistorted three–dimensional information of the maxillofacial skeleton as well as three–dimensional images of the teeth and their surrounding tissues. In periodontology, CBCT was up till now only used for some confined indications. The present contribution presents current study results and analyses these critically in respect to clinical experience. Hereby some successful applications of CBCT were shown in periodontolgy. Especially the graduation of furcation defects in molars and the evaluation of infrabony defects as well as the detection of perio–endodontic–lesions can be facilitated by CBCT technology.
