Lecture Description
Introduction : For satisfactory results of orthodontic treatment, practitioners require precise diagnosis not only on the dentition and occlusion of the patients, but also on the skeletal structures including bone and cartilage, and on the facial soft tissues including skins, connective tissues, fats and muscles.
Discussion : In the history of orthodontic and orthognathic treatment inherited from Angle¡¯s paradigm, accomplishing ideal hard tissue relations have always had priority. Therefore, the cephalometric radiographs and the dental models maintained their position as essential diagnostic tools, while the soft tissue relations were only limited to the 2-dimensional (2D) facial photos. In the meantime, 3-dimensional (3D) diagnostic tools as cone-beam computed tomography (CBCT) and intraoral scanners have developed and came into the general use in orthodontic treatment. Consequently, demands for 3D surface images of patient¡¯s soft tissue which can be integrated to the 3D hard tissue image are increasing and some commercialized products have been introduced for clinical usage.
Conclusion : With the appropriate use of 3D surface image, clinicians can establish an ideal treatment plan that contains extensive information and changes of patient¡¯s soft tissue. In this presentation, the understanding and application of 3D surface image to be integrated to the 3D hard tissue images will be discussed for the orthodontic/orthognathic treatment.
