Measurement of thickness of connective tissue attachment and free gingival thickness Click here to view.

Assessment of dentogingivak depth Click here to view. The APE was diagnosed when these criteria were met in the context of a patient with a clinically apparent short dental crown Fig. Relationships between alveolar bone levels measured at surgery estimated by transgingival probing and clinical attachment level measurements.

The preservation of a healthy periodontal attachment is a prerequisite dentogkngival successful restorative procedures. Our own results support this idea. Transgingival probing as a potential estimator of alveolar bone level.

The selection focused on ensuring the maximum inclusion of subjects with upper anterior teeth presenting clinical evidence of APE.

A more precise classification, based on histologic findings of clinical situations in the adult exhibiting deviations dentoginngival this normality, has been unlt.

In the present series we observed no such relation, since in no case did the manual probe depth exceed 3 mm — the most frequent value being 1. Measurements were obtained of the thickness of the buccal bone plate at crest level, at the middle third, and at the apical third.

In this way it is possible to correlate the clinical diagnosis with the radiological diagnosis. A total of individuals participated in the study. Statistical analysis confirms two morphological patterns of APE. Fig Subgingival root fracture. The mucogingival line was located by means of the Coppes technique pushes of the mucosawhile the gingival width was determined using a graded periodontal probe, measuring from the mucogingival line to the gingival margin in the medial zone and expressing the results in millimeters.


Walter Reed Army Medical Center; How to cite this URL: The reproducibility of the PPRx technique was assessed by means of a double experiment.

These results suggest that the dimensions of DGU are highly variable in humans. 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. The development of the periodontium-a largely ectomesenchymally derived unit. Tooth eruption dentoginyival two phases 7: University of Amsterdam; The APE is characterized by: Introduction The dentogingival unit DGU has been described as a dentogingivzl unit composed of the epithelial attachment and connective tissue attachment of the gingiva — both of which afford biological protection 1.

The location of the demtogingival of the gingival attachment at the cementoenamel junction CEJ is considered by many a transitional stage. PPRx was a highly reproducible exploratory technique. In our series the mean distance was found to be 1.

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

Pearson dentogingigal correlation coefficient was calculated to examine the agreement between the values obtained by PPRx and transgingival probing. Lip, tongue, and muscle interferences have been suggested among the reasons that prevent teeth from exhibiting a normal and total eruption. The mucogingival junction is situated at a level coronal to the alveolar crest, and the anatomic relationships existing between the other elements appear normal.


The same examiner F.

Altered passive eruption APE: It has been demonstrated that margin placement, fit of restoration, restorative material, emergence profile, and tooth contour are factors that may contribute to the disturbance of this state of health.

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

It may be that passive eruption or the apical shift of the gingivo-epithelial junction is not a physiologic process. Intrasulcular margin placement must be accepted as inevitable. The blue line reflects the proportion of cases not presenting APE for an overlap less than or equal to that indicated on the abscissas axis.

Accordingly, a disproportionate dimension of these tissues with respect to tooth size or eruption capacity would complicate both passage of the tooth during the active eruption phase and tissue withdrawal during the passive phase of eruption.

In so doing it establishes a firm union with the cemental surface. This article has been cited by 1 Biologic width dimensions – a systematic review Julia C. Thickness of gingival obtained by PPRx technique Click here to view.
