Effect of Connective Tissue Graft Position

The Effects of Connective Tissue Graft Position on Clinical and Aesthetical Outcomes of Gingival Recession Treatment. A Controlled Randomized Clinical Trial

Aim: The aim of this study was to compare the root coverage and aesthetic results of CAF+ CTG positioned apical to the CEJ (CAF+CTG-ACEJ) with CAF+CTG positioned on the CEJ (CAF+CTG-CEJ) for treating isolated gingival recession defects.

Methods: Thirthy-eight patients with Miller class I and II gingival recessions were enrolled. 19 patients were randomly assigned to the CAF+CTG-ACEJ group or CAF+CTG-CEJ group. Clinical and aesthetical evaluations were made at 6 months.

Inclusion Criteria:

• 19 years of age,

  • Periodontally and systemically healthy,
  • FMPS and FMBS <15%,
  • Presence of Miller Class I/II GR defect (≥3 mm in depth) at the buccal aspect of incisors and canines,
  • Presence of identifiable CEJ (step ≤1 mm at CEJ level and/or presence of a root irregularity/abrasion with identifiable CEJ, was accepted),
  • No previous periodontal surgery.

Exclusion Criteria:

• Smoking,
• Contraindications for surgery,
• Presence of recession defects associated with caries, deep abrasion, restoration or pulpal pathology.
