DEEPBITE

Malocclusion can occur in three planes of space i.e. sagittal, transverse and vertical plane. Dental vertical relationships can be divided into four major categories: anterior open bite, anterior deep bite, posterior open bite and posterior collapsed bite with overclosure. Since the same occlusal relations can result from skeletal jaw proportions or from infraeruption or supraeruption of teeth, the descriptive terminology should be as precise as possible in indicating whether jaw or tooth positions are basically at fault in producing a vertical problem. The maxillary dental arch being larger than the mandibular dental arch allows the maxillary anteriors to overlap the mandibular anteriors. This overlapping of the mandibular teeth occurs in both the horizontal as well as vertical direction
