Two variants of normal occlusion (bite) are distinguished according to the relations of the upper anterior teeth to the lower anterior teeth in the vestibule-oral direction. The first variant is called the scissor-like bite (paslidodontia) (Gk psalis scissors, odus tooth). It is encountered in most individuals (in 79.6 percent according to certain data). In this type of occlusion, the cutting edges of the upper teeth overlap the cutting edges of the lower anterior teeth and convert 1.5-3.0 mm of the labial surface of the lower teeth with their lingual surface.Medical Coding Services will help you to do collections and also the pending amounts from the patients.
