In relation to the soft tissues, the subepithelial connective tissue graft practically doubled the values found in the contralateral tooth (8.2 mm versus 4.6 mm cervical, 11.2 mm versus 6.9 mm apical), being of paramount importance for maintaining a stable gingival margin and avoiding possible recessions that can affect the vestibular face of the immediate implants.
In the region of2.1, a small band of keratinized tissue (1 mm) was found apical to the gingival margin, and scars extending from the region of1.1 to 2.2 were found (Figure 1).
Even with complete root coverage; the incision scar, gingival color, and gingival margin contour also affect the esthetic appearance.
To achieve laser analgaesia, the laser was positioned at a distance of 2mm from the tooth surface on the gingival margin and slowly moved for 2min duration using 60 mJ energy and 20 Hz frequency power (low energy, high frequency).
He further said that that plaque is a complex biofilm containing various microorganisms form mainly on teeth and particularly between them, along the gingival margin, and in fissures and pits, adhering by a variety of mechanisms.
Natural teeth, with rare exceptions caused by individual variation, (9) present rectilinear contour in the gingival margin and an arched coronary contour from the cementoenamel line towards the occlusal aspect.
Remove and mark the gingival margin on the provisional restoration with a sharp lead pencil.
In addition to the loss of attached gingiva, observations in this case included ulcerations at the free gingival margin, tooth abrasion, deposits of dental plaque related to the affected area and an increase in dental hypersensitivity.
These include shallow probing depths [less than or equal to] 3mm, with the gingival margin located at, or slightly coronal to, the cementoenamel junction (CEJ); the absence of bleeding on probing or other indications of inflammation; and the normal appearance and location of the alveolar crest as viewed radiographically.
Sixty proximal boxes with the gingival margin below the CEJ were cut in extracted posterior teeth and cavities were divided into three equal groups.
This approach may result in a poor gingival margin, inadequate gingival tissue attachment, and a discrepancy of the gingival level between the exposed tooth and its neighboring teeth.
