Chatsworth, CA, September 25, 2008—Dolphin 3D was used in a study at the University of North Carolina, Chapel Hill, in efforts to determine what statistical difference might exist between measurements taken from conventional cephalograms, and those synthesized from CBCT datasets. Published in Angle Orthodontist, Vol 78, No 5, 2008, the study revealed that both angular and linear measurements were not statistically different for either modality.
In addition to asserting that the Dolphin 3D software is “…much more user friendly than the scanner’s current software…”, the study’s authors made some other important conclusions that greatly impact our industry: First, “…synthesized cephalometric images from CBCT may be used to bridge the transition from 2D to 3D image analysis” and second, “…CBCT cephalometric image reconstruction can be recommended as an alternative to conventional cephalograms when a CBCT volume is already available, thus reducing the need for additional x-ray exposure and examination expense.” Further, in cases where landmarks are visually ambiguous (such as gonion and condylion), the CBCT-generated cephalograms may offer more accurate identification—and therefore more truthful anatomical measurements—than conventional cephalograms.
