The mean biologic width by the parallel profile radiography PPRx technique was 1.

University of Amsterdam; Fig Passive eruption describes the apical shift of the gingival attachment along the root surface.

The same examiner F. The molar and canine Angle occlusion class was recorded. Reproducibility of pocket depth and attachment level measurements using a flexible stent.

Morphology and dimensions of the dentogingival unit in the altered passive eruption

Altered passive eruption APE: Although width can also be assessed by transgingival probing or with an ultrasound device, they are either invasive or expensive Aims: Therefore, in our series of teeth, attrition was scantly relevant to crown length. Indian J Dent Res ; It should be impressed and visualized whenever clinical practice reaches the gingival level. The mucogingival junction is located coronal or at the level of the alveolar crest. Parallel profile radiography PPRx was used to this effect 4.

Assessment of sulcus depth Click here to view. A index for measuring the wear of teeth. Walter Reed Army Medical Center; The dentogingival unit The dentogingival unit is composed of two parts: The PPRx allows us to measure discrepancy and the degree of overlap 4. Galgali SR, Gontiya G.

Morphology and dimensions of the dentogingival unit in the altered passive eruption

The dimensions of human dentogingivak junction. Support Center Support Center. As age progresses the epithelium is apt to proliferate in an apical direction. A first analysis was made of the correlation between the clinical diagnosis of tooth teeth 21 i. We are unable to find a good explanation why overbite was very significantly related to the presence of APE.

Dentogingival unit, unot thickness, transgingival probing, radiographs. Statistical analysis confirms the presence of two morphological patterns of APE, respectively characterized by a longer and shorter distance from cementoenamel junction to bone crest.

Fig This diagrammatic representation has been progressively developed by the studies of a number of authors. Thus, the PPRx technique offers a simple, concise, dentogungival, and reproducible method that can be used in the clinical setup to measure both the length and thickness of the DGU with accuracy.

Measurements were obtained of the thickness of the buccal bone plate at crest level, at the middle third, and at the apical third. The biologic width appears to exist in any periodontium, and the importance of not violating this physiologic dimension was suggested by Ochsenbein and Ross 9 and stressed by other authors.


Transgingival probing trans-sulcular was done for these same patients and length of the DGU was measured. The ‘Biologic width’ a concept in periodntics and restorative dentistry. This procedure made possible margin placement without violating the biological width.

Dimensions and relations of the dentogingival junctions in humans. Please review our privacy policy. Maintenance of gingival health is a key factor for longevity of the teeth as well as of restorations. This article has been cited by. Relationships between alveolar bone levels measured at surgery estimated by transgingival probing and clinical attachment level measurements. Ultrasonic determination of gingival thickness.

In a healthy state, the gingival margin is generally located on the enamel and the junctional epithelium from the base of the sulcus to the CEJ, and the gingival fiber apparatus takes place between the osseous crest and the CEJ. Such space restrictions could be conditioned by the type of facial growth pattern involved, and which would ultimately regulate the vertical space relationship between the two basal maxillary and mandibular bones. Two subjective criteria were contemplated for the clinical diagnosis of APE: A total of individuals participated in the study.

The length and width of the DGU was measured using computer software.

Discussion The literature lacks references for calibrating the magnitude of gingival overlap characterizing APE.
