详细描述

Comparative Evaluation of laterally Closed Tunnel (LCT) Technique and Modified Coronally Advanced Tunnel (MCAT) Technique in the treatment of isolated gingival recession: Randomized controlled clinical trial.

Proposal Submitted in Partial Fulfillment of the Requirements of Doctor of philosophy Degree in Oral Medicine and Periodontology BY Ahmed Mohamed El-Bana B.D.S, MSC (Mansoura University, 2014) Assistant lecturer at Oral Medicine, Periodontology, Oral Diagnosis and Radiology Department 2021

Gingiva represents one of the important defense barriers of the periodontium and any alteration of its conditions may result in detrimental effects on the stability of the periodontium. Gingival recession is a common mucogingival problem that is associated with apical migration of the gingival margin and exposure of the root surface.Various factors are associated with increased incidence of gingival recession such as plaque-induced inflammation, violation of the biological width of the gingiva, aggressive teeth brushing and high frenulum attachment.

Various surgical techniques were described for the treatment of gingival recession from which, the coronally advanced flap (CAF) is one of the most commonly used techniques for root coverage of miller class I, II. Many modifications of CAF have been used to get the best treatment outcomes. The CAF can be used alone or in combination with connective tissue graft [CTG], platelet rich fibrin , enamel matrix derivative or any other regenerative materials. Various systematic reviews have reported the efficacy of CAF as the gold standard protocol for gingival recession treatment especially if used with CTG.

Tension free healing is the main goal to get the ideal results of gingival recession correction, which was difficult to achieve with a coronal displacement of the tunnel. In addition, the vestibular depth distortion was related to the procedures due to tissue tension. Therefore new clinical approaches are warranted to be more predictable and to minimize the post-operative complications.

研究组 & 干预措施

The Laterally Closed Tunnel Technique with SCTG

Experimental

An aseptic field was required for all surgical procedures using povidine iodine. Local anesthesia using 4% articane with 1:100.000 epinephrine was applied.•

  • Then specially designed tunneling instruments [devmed] were used through the sulcular incision to create a pouch.
  • A microsurgical blade was used at the inner surface of the pouch till sufficient tissue release was achieved.
  • Tissue forceps was used to approximate the mesial and distal margin of the gingiva at the pouch margin.
  • After harvesting the graft, it was placed at the prepared pouch after root surface biomodification using EDTA gel 24% for 2 minutes and copious rinsing with saline solution.
  • SCTG was pulled using single or mattress sutures and the graft was fixed mesial and distal at the inner part of the pouch using resorbable suture material [Vicryl suture], then the graft was sutured around the neck of the CEJ by sling suture 6/0 polypropylene.
