Fernrntgenaufnahme versus Computertomogramm: Vergleich von Referenzpunktreproduzierbarkeit und Przision sowie bereinstimmung kep,Used
Delivery time: 8-12 business days (International)
Die Fernrntgenanalyse stellt heutzutage einen unverzichtbaren Bestandteil der kieferorthopdischen Befunderhebung dar. Neben den Mglichkeiten, die die Analyse der seitlichen Fernrntgenaufnahme bietet, mssen auch ihre Einschrnkungen bedacht werden. So wird ein dreidimensionales "Objekt" auf eine Ebene projiziert und in den verbleibenden zwei Dimensionen untersucht, was die wahrheitsgetreue Erfassung wichtiger Strukturmerkmale und der tatschlichen Konfiguration skelettaler Fehlbildungen einschrnkt. Die dreidimensionale Bildgebung auf CTBasis ermglicht demgegenber eine berlagerungsfreie, anatomisch wahrheitsgetreue Darstellung ohne geometrische Fehler, eine Visualisierung innerer Strukturen des Schdels, eine virtuelle Entfernung von Knochenstrukturen zur Verbesserung der Ansicht sowie eine angemessene Weichgewebedarstellung. Zur Klrung der Frage, inwiefern die technischen Unterschiede beider Aufnahmemethoden zu Abweichungen in der kephalometrischen Analyse fhren, berprft der Autor Referenzpunkte im FRS und CT auf Ihre Reproduzierbarkeit, vergleicht die Przision kephalometrischer Strecken und Winkelmessungen und untersucht die bereinstimmung beider Messmethoden.
