Syfte: Undersöka om skillnad föreligger mellan panorama- och CBCT-röntgen i avseende att bedöma den vertikala höjden av alveolarutskottet vid planering inför implantatbehandling i utvalda regioner. Metod och material: Totalt valdes 68 röntgenbilder, 34 panorama- respektive 34 CBCT-bilder, ut. I samtliga röntgenbilder utfördes mätningar av alveolarutskottets vertikala höjd, vid specifikt utvalda regioner. Observatörerna bestod av fem tandläkarstudenter. Resultat: Både med och utan hänsyn till outliers, visar resultatet en signifikant skillnad mellan de båda röntgenmetoderna. Generellt visas att mätningar i panoramaröntgenbilder återger ett kortare avstånd mellan alveolarutskottets högsta punkt och sinus maxillaris nedre begränsning/foramen mentales övre begränsning jämfört med mätningar i CBCT-röntgenbilderna. Konklusion: Det fanns en signifikant skillnad mellan de båda röntgenmetoderna, denna studie visade att en kortare vertikal benhöjd mättes i panorama- jämfört med i CBCT-röntgenbilder. Resultatet visade att det fanns försumbara interobservatörsskillnader. / Purpose: Investigate whether there is a difference between the panoramic and CBCT X-ray in terms of assessing the vertical height of the alveolar ridge when planning for implant treatment in selected regions. Methodology: A total of 68 X-ray images, 34 panoramic and 34 CBCT images, were selected. In all X-ray images, measurements of the vertical height of the alveolar ridge were performed at specifically selected regions. The observers consisted of five dental students. Results: The result of this study shows a significant difference between the two X-ray methodologies. The measurements made in the panoramic pictures shows a shorter distance between the highest point of the alveolar bone and the lowest point of the maxillary sinus (or the upper limitation of the mental foramen) compared to the same measurements made in the CBCT pictures. Conclusion: There was a significant difference between the two X-ray methods, this study shows that a lower vertical bone height was measured in panoramic compared to CBCT X-rays. The result showed that there were insignificant inter-observer differences.
