Anterior interocclusal relations. Part II.

Part I of this article pointed out that correction of discrepancies in anterior interocclusal dental arch length may be accomplished by increasing the lingual and distal inclination of the upper anterior teeth and/or by mesiodistal crown reduction of the lower anterior teeth. Part II will discuss three-mandibular-incisor cases in which it was possible to establish normal anterior interocclusal relation in treatment of the following problems: deficient upper anterior dental arch length, missing upper and/or lower anterior teeth. Class II maxillary protrusion nongrowers with procumbent or crowded lower anterior teeth, and Class I bimaxillary protrusion with crowding of the anterior teeth.
