Correction Of Excessive Gingival Display: Lip Repositioning With/ With. Lip Repositioning

      Аннотация: Tooth related factors that contribute to EGD include: dentoalveolar extrusion and altered passive eruption (APE). Dentoalveolar extrusion will present with anterior teeth that possess a curved or concave gingival line in relation to the horizon (Robbins, 1999). This condition can affect any teeth in the mouth and can be caused by: teeth supraeruption secondary to incisal wear, supraeruption secondary to lack of opposing teeth, anterior teeth without appropriate opposing contact, or due to a developmental cant. Treatment options for dentoalveolar extrusion include: functional crown lengthening surgery, orthodontic intrusion–via temporary anchorage devices or surgically facilitated orthodontics–and the teeth are then restored at an appropriate incisal edge position. To fully explain the definition of APE, first passive eruption must be defined.
