Accepted Answer

An open bite refers to open contact between the arches.While open bite can occur in the posterior areas,it is most common in anterior regions.A diastema is a space between two adjacent teeth;a contact area is lacking.Overjet is the amount of facial horizontal overlap of the maxillary teeth to the mandibular teeth.A premature contact is an occlusal interference where one tooth hits ever so slightly before the others.A crossbite occurs when one or more of the mandibular teeth are located facial to the maxillary counterparts.
