Applicability of Novel 3D classification system for maxillary canines in cleft lip and palate patients using KPG Index- A CBCT Study

Cleft lip and palate (CLCP) is the disorder which is characterized as opening or splits in upper lip or palate of the oral cavity or both. Studies have come to noticed the cause of CLCP among individuals is due to the interactions of genetic and environmental factors. Third molars are the frequent impacted teeth followed by upper arch cuspids. Recent development in 3D imaging has been gold standard method in dentistry especially in orthodontics. Evolution in development of Cone Beam Computed Technology has helped in localization of impacted tooth. The KPG index is the first-ever 3D classification system for locating impacted canines in patients with cleft lip and palate based on their distance from the normal. KPG index and 3D CBCT imaging along with further validation has become increasingly beneficial in determining the possibility of eruption of impacted canine.Cleft lip and palate (CLCP) is the disorder which is characterized as opening or splits in upper lip or palate of the oral cavity or both.
