Long-term Outcomes of Tunnel Technique

The patient received 600 mg of ibuprofen (paracetamol 1 g in case of allergy) prior to surgery, and chlorhexidine mouthwash 0.2% was provided for 2 min. Patients received local anaesthesia at the donor and recession sites (articaine hydrochloride 7200 mg/1.8 ml, adrenalin 1800 mcg/1.8 ml). CTG harvesting was performed prior to the preparation of the reception site to avoid any bias. The graft dimension was calculated according to the recession dimensions; a minimum of 3 mm of the graft was submerged mesially, distally and apically. The CTG was harvested from the palate with single edge incision and sutured with 4.0 silk. The patient was subsequently assigned randomly to the control (CAF+CTG) or the test group (TUN+CTG).
