A Closed Surgical Technique vs Papilla Preservation Techniques

No results posted yet for this study

Summary

A pioneer periodontal surgical approach employing the closed surgical technique (CST) has been designed to gain access to isolated interdental periodontal defects and retain the soft-tissue architecture. This technique is based on a modified tunnelling technique to retract full-thickness gingival flaps from the osseous defect in a closed manner retaining intact the interproximal papilla thus, suturing is not required. A randomised controlled clinical trial will determine the efficacy of the CST versus the access flap employing papilla preservation techniques over a period of 6 months.

Conditions

  • Periodontitis

Interventions

PROCEDURE

Access Flap

Intrasulcular incisions at the teeth adjacent to the defect, using the simplified papilla preservation technique (SPPT) or modified papilla preservation technique (MPPT). Granulation tissue is excised and debridement via hand and power-driven instruments follows. Flaps are repositioned and papilla are sutured with horizontal internal mattress doubled by a single interrupted interdental suture.

PROCEDURE

Closed Surgical Technique

Strictly intrasulcular incisions are performed at the teeth adjacent to the defect (mid-buccal to mid-lingual) without incising the interdental papilla. Full thickness gingival flaps, at the base of the papilla, which is retained intact, are elevated in a "closed"-tunneling manner, granting access to the interdental osseous defect. Debridement is performed via power-driven tips and mini curettes, without intentionally excising the granulation tissue that lines the osseous defect. Flaps are repositioned by gentle pressure and suturing is not required.
