Producing 3D surface models from cone beam computerized tomography (CBCT) datasets is still less accurate than the reality when using threshold based methods. Differences in the segmentation process resulted in significant clinical differences between the measurements. The commercially segmented surface models were more accurate than the experienced clinician’s segmented surface models. However, equal quality may also be reached by a clinician if sufficient training and time is taken to segment a CBCT surface model. Because CBCT images are often used for pre-surgical planning, the accuracy is of utmost importance. There are clear potential benefits of using 3D measurements as opposed to direct measurements in the assessment of facial deformities. Measurements recorded by 3D systems appeared to be both sufficiently accurate and reliable enough for research and clinical use. The soft tissue measurements on surface models derived from CBCT are reliable and accurate. Existing CBCT images can be used to derive accurate measurements for establishing soft tissue thickness databases of different populations.
