A Closed Surgical Technique vs Papilla Preservation Techniques (CST)
Treatment of Residual Periodontal Pockets
About this trial
This is an interventional treatment trial for Treatment of Residual Periodontal Pockets focused on measuring interdental periodontal defect, periodontal surgery, papilla preservation, tunnelling technique, closed surgical technique
Eligibility Criteria
Inclusion Criteria: Systematically healthy subjects, not having consumed antibiotics 3 months before surgical periodontal treatment (baseline) Smokers <5 cig/day, former smokers or no smokers Periodontal patients fulfilling non surgical initial periodontal treatment at least 3 months before surgical periodontal treatment (baseline day) and presenting at least one residual pocket with PPD and CAL ≥6mm and bleeding on probing, located interproximally with intrerdental site ≥2mm. Compliant patients presenting high standards of oral hygiene (full mouth Plaque Index <20%) strictly susceptible in Supportive Periodontal Treatment Exclusion Criteria: Untreated active periodontal inflammation Poorly controlled systematic diseases Disorders compromise wound healing Bisphosphonate medications Patients under radiotherapy or chemotherapy Drug-indused gingival hyperplasia Pregnancy or lactation Poor compliance during steps 1 and 2 of cause-related periodontal treatment Compromised oral hygiene (full mouth Plaque Index >30%), circumferential bone defect or narrow intrerdental site ≤2mm.

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.
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 intentional excising the granulation tissue that lines the osseous defect. Flaps are repositioned by gentle pressure and suturing is not required.
