Study Notes

Occlusion of the Tooth - Flashcards Study Notes

Class II, division II malocclusion is linked to a deep overbite.
An open bite can occur even if anterior incisors are touching edge to edge.
Severe protrusion of maxillary incisors often results in increased overjet.
Retruded teeth are inclined towards the tongue (lingually).
The absence of permanent first molars complicates occlusion determination, but canines can still provide information.
In acromegaly, the mandible does not grow faster than the maxilla; rather, the maxilla grows more rapidly.
Alignment refers to the straight arrangement of teeth in a row, essential for proper occlusion.
Leeway space is the additional space taken by deciduous canines and molars, aiding the eruption of permanent teeth.
Primate space consists of diastemas located next to the deciduous canines.
Diastemas are the gaps found between individual teeth.
Occlusion denotes the relationship between maxillary and mandibular teeth when the jaws are closed.
Centric occlusion is characterized by optimal interdigitation of the teeth during jaw closure.
Class II, division II occlusion may exhibit features like a deep overbite, crowded maxillary incisors, a normal overjet, and distocclusion.
Class III occlusion is typically associated with a prognathic mandibular jaw.
Overbite can be described in terms of vertical overlap.
Class I occlusion occurs when the mesiobuccal cusp of the maxillary first molar aligns directly above the buccal groove of the mandibular first molar.
Class III occlusion is the least common type of occlusion.
In Class III occlusion, the distal surface of the permanent mandibular canine is mesial to the mesial surface of the permanent maxillary canine by at least the width of one tooth.
Crossbite occurs when permanent mandibular molars are positioned buccal to the maxillary molars.
Posteriors are the teeth that ideally occlude in centric occlusion.
Anteriors are the teeth that make contact during ideal protrusive movements.
Group function refers to the occlusion of the premolars during lateral excursions.
