Aim: The aim of the presented study was to establish whether we can find differences in facial soft tissues morphology in patients with cleft palate compared to normal population using 3D facial scan, and to present a non-invasive examination method of 3D morphometrics. Material and method: The sample of patients included 22 men and 26 women. The most frequent in the patients was cleft hard and soft palate (83%), followed by submucous cleft palate (15%), and cleft soft palate (2%). The age of patients was within the interval 8 years and 1 months and 13 years and 11 months. The sample was subdivided into three groups according to the age. Measurements were performed with optical scanner 3dMDface System. The shape of cleft patient’s face was compared with physiologically average face of the controls of the given age and sex with SD score. Deviations between the scans were visualized with colour score in each patient. Results: In most patients the extent of cleft defect correlates with the extent of morphological changes of facial soft tissues. The mean deviation comparing facial maps of patients with cleft palate and the control group is 1.5 (SD). Conclusion: The results suggest that changes in facial soft tissues in patients with cleft palate are expressed.

Shade guide selection is one of the elementary procedures commonly performed prior to a tooth restorative or prosthodontic treatment. Natural tooth appearance is very complex. A dentist or a technician can easily misunderstand particular aspects of light behaviour, which lead to an inappropriate shade selection and unsatisfactory esthetic results. It is essential to understand the basics of color – HSV (Munsell) color system. This article emphasizes photography as a useful tool for precision selection of the most important parameters, Value, Hue and Chroma in a basic photoprotocol.

Článok prináša pohľad do oblasti skenovania tváre v ortodoncii ako aj fúzie takéhoto 3D záznamu s celohlavovým CBCT iCAT™ skenom. Autor popisuje vlastné skúsenosti s 3D tlačou takéhoto kombinovaného modelu a orientačne posudzuje presnosi reprodukcie medzi reálnym modelom, virtuálnym 3D modelom a vytlačeným modelom. Vysvetľuje tiež princípy a rozdiely medzi aktívnou a pasívnou stereofotogrametriou a tiež porovnáva skúsenosti medzi jednotlivými stereoskopickými kamerami: 3DMD TM, 3D-Shape™ a D/3D™. Článok tiež venuje pozornosí perspektívam klinického využitia uvedených technologických postupov.
The article reviews the face-scanning procedures and technologies in orthodontics, as well as the fusion of such face-scans with CBCT iCAT TM scans. The author gives his own experience with 3D print of the fused face-CBCT model, and evaluates in brief the accuracy of a reproduction in vivo, a virtual 3D model, and a printed 3D model. The basic principles and differences between active and passive stereophotogrammetry are explained, and the experience with different stereoscopic cameras 3DMD TM, 3D-Shape TM, and Dl3D TM is discussed. The article also gives the current view on perspectives and the use of the technologies described in clinical orthodontics.
