Evaluation of Subepithelial Connective Tissue Graft Versus Acellular Dermal Matrix With Tunnel Technique in Treatment of Multiple Gingival Recessions

Cairo University (CU)

Status: Unknown

Conditions: Gingival Recession

Treatments: Procedure: Tunnel technique with the subepithelial connective tissue graft; Biological: Acellular Dermal Matrix

Study type: Interventional

Funder types: Other

Identifiers

Details and patient eligibility

About

The goal of the present study is to compare the amount of root coverage resulting from subepithelial connective tissue graft and acellular dermal matrix associated with tunnel technique among patients suffering from multiple gingival recession.

Full description

Acellular dermal matrix with Tunnel technique will offers great advantages for patients with multiple gingival recession as regards decrease surgical time, Post-Operative pain and root coverage, clinical attachment level, width of Keratinized gingiva, gingival biotype compared to subepithelial connective tissue graft with Tunnel technique.

Enrollment: 68 estimated patients

Sex: All

Ages: 18 to 60 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Subjects with facial multiple gingival recession defects classified as either class I or II defects according to Miller's classification (Miller 1985).
• Subjects aged between 18 - 60 years old.
• Patients should be free from any systemic disease that may affect normal healing of tissue, and predictable outcome.
• Patients with good oral hygiene.

Exclusion criteria

• Current and former smokers.
• Pregnant females.
• Subjects received any periodontal therapy for minimum of 6 months prior to the study.
• Subjects taking drugs known to interfere with wound healing.
• Subjects with unacceptable oral hygiene with plaque index >2.
• Teeth with non-carious cervical lesions (NCCL), cervical caries and malalignment.

Tunnel technique with acellular dermal matrix

Experimental group

Description:

the tunnel technique involves separation of the gingiva, then acellular dermal matrix interposed between the flap and the root surface.

Treatment:

Biological: Acellular Dermal Matrix

Procedure: Tunnel technique with the subepithelial connective tissue graft

subepithelial connective tissue graft

Active Comparator group

Description:

Tunnel is prepared and sub-epithelial connective tissue graft is harvested from the palate and placed under the flap.

Treatment:

Biological: Acellular Dermal Matrix

Procedure: Tunnel technique with the subepithelial connective tissue graft
