Summary

Different surgical techniques have been proposed for root coverage, showing varying results especially in areas of deep recessions. The aim of this study is to evaluate the effectiveness of the newly forming bone technique (NFB)as an alternative treatment for Miller class I or II deep recessions, requiring regeneration of lost periodontal tissues. Sample should be comprised of patients aged 18-45 years, both genders, presenting at least one site with marginal tissue recession \>4mm. Patients will be randomly assigned to either one of the groups, based on treatment technique: newly forming bone (NFB) or subepithelial connective tissue graft (SCTG). Clinical examinations will be performed by a single blinded examiner at baseline, 1, 3, 6 and 9 months after surgery. Intra-group analysis will be performed by one way analysis of variance for repeated measures. Inter-group analysis will be performed by unpaired t-test for each of evaluation periods.

Conditions

  • Gingival Recession

Interventions

PROCEDURE

Newly forming bone technique for root coverage

A granulation tissue will be obtained 21-25 days after the creation of an alveolar socket and grafted to receptor site.

OTHER

Subepithelial connective tissue graft for root coverage.

A subepithelial connective tissue graft will be used for the treatment of Miller class I or II deep recessions.
