Summary

Introduction:

Gingival recession is a lesion characterized by the loss of attachment of root surface of the tooth, resulting in an apical migration of the gingival margin that occasionally generates aesthetic problems, hypersensitivity and difficulty in maintaining proper hygiene.

Several anatomical factors have been associated both with the incidence and progression of gingival recession and with the prognosis of the surgical treatments proposed for its correction. These factors include the absence of keratinized tissue, the gingival phenotype, root prominence and shallow vesrtibular depth.

Objectives:

The objective of the study is to evaluate, through a series of prospective cases, the influence of each of the anatomical factors on the success of root coverage.

Methods:

20 patients with gingival recession defects will be treated with CAF+CTG using various autogenous gingival graft. Three-dimensional analysis of superimposed preoperative and postoperative images will be performed. Linear and surface root coverage will be calculated and correlated to various anatomical parameters such as vestibular depth and root prominence. A multilevel statistical analysis will be conducted, adjusting for the correlation among multiple observations.

Conditions

  • Gingival Recession
  • Gingival Diseases
  • Periodontal Attachment Loss

Interventions

PROCEDURE

Coronally advanced flap and connective tissue graft

CAF+CTG treatment will be performed by starting with two vertical releasing incisions lateral to the teeth to be treated and split-full-split thickness flap will be raised beyond the MGJ. The periosteum will be cut, and a blunt dissection into the vestibular lining mucosa will be carried out to eliminate muscle tension so that the mucosal flap can be passively positioned above the level of CEJ on the tooth. The papillae adjacent to the involved teeth will be de-epithelialized. CTG of 1mm in thickness will be harvested from the posterior palate by means of disepithelization of a free gingival graft, cut to the exact size of the defect, and placed over the dehisced defect, sutured to the interdental papillae and subsequently covered with CAF. Sling sutures will be placed to stabilize the flap in a coronal position about 1-2 mm above the CEJ , followed by interrupted sutures to close the releasing incisions.
