Delayed passive eruption: A predisposing factor to Vincent infection? J Dent Ass S Afr. Difficult to detect, most of these cases go undiagnosed or misdiagnosed. We recognize two Types (1 and 2) and two Sub-.types (A and B) depending on the position of the soft tissue and of the bone ridge in relation to the CEJ. In: Frontiers in dental and facial esthetics, JA McNamara, Ed., Craniofacial Growth Series, Center for Human Growth and Development, Needham Press, University of Michigan, Ann Arbor, Michigan 2001 Altered Passive Eruption (APE) When your permanent teeth come through, a process called 'passive eruption' occurs in which the bone retreats roughly 2mm below the area where the root meets the crown, and the gum moves with the bone to cover the tooth. Altered passive eruption is a condition in prominence rather than at the cementoenamel junction. Altered Passive Eruption is not a disease, but a condition subsequent to a relationship between the bone, the tooth and the soft tissue after teeth eruption that is today often considered aesthetically unpleasant. Treatment plan was elaborated to the patient, and a written informed consent was acquired. To correct excessive gingival display esthetic crown lengthening procedure by gingivectomy was planned along with gingival depigmentation. Maximizing anterior esthetics: An interdisciplinary approach. Altered passive eruption is the condition in which the gingival unit fails to migrate physiologically apical to CEJ. Dimensions and relations of the dento-gingival junction in humans. 2) showed that the incisor teeth were not fully erupted.While the short clinical crowns could be due to occlusal wear or delayed tooth eruption, another possibility was that altered passive eruption (APE) was present, which is a predisposing factor to NUG. Studies that estimate the prevalence of APE in adults are poor to date, possibly because of the lack of standard diagnostic criteria.
Diagnosis and classification of delayed passive eruption of the dentogingival junction in the adult. Figure 2: Altered passive eruption type 1A as diagnosis Discussion Altered passive eruption is an unesthetic short clinical crowns with gummy smile which affects the subjects psychologically.
