Int J Periodontics Restorative Dent.

The length and width of the DGU was measured using computer software. An excessive amount of gingiva covering in the occlusal direction of the anatomic crown can be noted. The purpose of the denrogingival was to further knowledge of the morphological features of APE at DGU level, with the following specific aims: Altered passive eruption APE: 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.

This clinical situation presents, on the buccal level, similarities to that described in Figand suggests treatment possibilities. Our own results support this notion. Pathogenesis of periodontal disease and its treatment.

From Coslet et al. The selection focused on ensuring the maximum inclusion of subjects with upper anterior teeth presenting clinical evidence of Denfogingival. Fig Subgingival root fracture. University of Amsterdam; Maintenance of gingival health is a key factor for longevity of the teeth as well as of restorations.

It has been demonstrated dentogingivap 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.

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

Table 2 presents the average dimensions for each variable examined in the PPRx study. This article has been cited by 1 Biologic width dimensions – a systematic review Julia C. Indian J Dent Res ; Two types of exploration were carried out in second sextant: Radiographic analysis of alveolar crest height and age. The precision of the technique was then evaluated by performing the radiographs in duplicate – each time completely dismounting and again mounting all the pieces of the paralleling system total: Walter Reed Army Medical Center; Related articles Dentogingival unit gingival thickness radiographs.


Esthetic Management of the Dentogingival Unit. The values obtained agree with the values obtained by transgingival probing, a technique considered standard so far. With the passive eruption phase, the gums migrate in the apical direction, with gradual exposure of the crown of the tooth and final stable localization of the DGU at cervical level.

Tooth maintenance does not leave any alternative for treatment other than lengthening the dental element to expose sufficient sound tooth structure coronally to the junctional epithelium for proper placement of the margin of the restoration. It may be that passive eruption or the apical shift of the gingivo-epithelial junction is not a physiologic process.

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

Many adults exhibit short anatomic crowns with gingival tissue located occlusally or incisally. The dimensions of the human dentogingival junction. Support Center Support Center. Healthy gingival tissue surrounding dental elements or dental restoration is part of structural beauty, and a protocol of treatment to maintain this state will be proposed in chapter Anatomical characteristics of gingivae – a clinical and microscopic study of free and attached gingivae.

The DGU is habitually located close to the cementoenamel junction, the gingival margin dfntogingival covering the limits of the dental crown 5. The mucogingival junction is located coronal or at the level of the alveolar crest.

The purpose of this study was to determine the dimensions of the DGU components for tooth 21 Fig. Thickness of gingival obtained by PPRx technique Click here to view. Please review our privacy policy. Fig Passive eruption describes the apical shift of the gingival attachment along the root surface. After demonstrating this correlation, an evaluation was dwntogingival of the percentage overlap that best distinguishes i.


From the statistical point of view, our series of patients presents these two dentoginngival patterns of APE. Clinical diagnostic criteria of altered passive eruption APE.

Upper lip height was measured as the distance from the base of the nose to the lower margin of the lip, with an evaluation of the amount dentogingivql gingival tissue exposed over the four upper incisors on smiling.

How to cite this article: Parallel profile radiography PPRx was used to this effect 4. A new exploration technique parallel profile radiograph.

The purpose of this division was to identify the variables related to APE and the particularities that may help differentiate the condition. Pathogenesis of Periodontal Disease and its Dentigingival. This article has been cited by other articles in PMC. And the length of the clinical crown was measured. A more precise classification, based on histologic findings of clinical situations in the adult exhibiting deviations from this normality, has been proposed. Material and Methods A total of individuals participated dentogingivak the study.

Relationships between alveolar bone levels measured at surgery estimated by transgingival probing and clinical attachment level measurements. This variation in habitual morphology involving a more coronal periodontium has been referred to as altered passive eruption APE or delayed passive eruption 6.

This could be explained by considering the fact that nearly all civilized dentogingigal have had a history of acute or chronic tissue inflammation, with a concomitant destruction of the connective fibrous attachment. Statistically significant differences were observed between the teeth with and without APE: Discussion The literature lacks references for calibrating the dentoginglval of gingival overlap characterizing APE.
