Abstract
Adult patients’ severe malocclusions, especially the skeletal ones, cannot be exclusively solved by the orthodontic treatment and therefore a combined orthodontic-surgical treatment is necessary. Today, numerous software allows to plane and to visualize the final treatment results simulating the best therapeutic option. This is a retrospective experimental study that aims to analyze the changes in the buccal cortical bone in patients undergoing orthodontics surgeries and to evaluate the correlation between the dental movement and the changes in the relative bone cortex. The study sample consists of 32 subjects. By applying the CBCT radiographic examinations, the measurements were made in well-defined points of reference. The 3D study of the dental changes of position and the cortical buccal bone related variation, suggests how the determined orthodontic movement of the dental element does not achieve an easily predictable bone variation. Therefore, it also suggests that there is no direct proportionality relationship between the extent of bone apposition/reabsorption and dental movement.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
