Introduction: Surgical crown lengthening is standard procedure for radicular rests usage and case series which include biologic width and ferrule effect being comprom ised. In the end o f this procedure a flap suturing is essential, with other words being said suturing may be the one who is going to make a difference between failure or success. This paper will analyze the type o f needle, type o f suture and technique o f suture and will contrast it to the present literature data. Purpose and Objectives: Materials and Methods: The present manuscript is presented as a retrospective study on the basis o f 63 consecutive patients. Considering the flap approximation as the main purpose o f flap suturing, different types o f sutures, needles, and suture materials were utilized. Types o f sutures used in periodontal surgery are mainly related to empirical background o f the surgeon. Results: Simple sutures was mainly used, all o f the 63 patients being treated by this mean. In a single case the 8 shape suture was used-due to bad access to the surgical wound. Mattress sutures were also mainly used because o f its maneuverability and secureness o f the flap stabilization. Vertical mattress sutures were used in 48 patients, and horizontal mattress sutures was used in 9 patients. Circumferential suture was used in 3 patients, mainly because the lack o f the papilla approximation following another type o f suture. Retromolar suture was used in 3 patients all o f this cases presented the need o f distal approximation due caries activity. Continuous suture was used for 23 patients. In all o f this cases different type o f sutures was used, mainly because flap suturing after surgical crown lengthening cannot be achieved by one suture alone. For 58 patients the suture material was polypropylene, for 5 silk, and in 9 cases vicril. polypropylene was the most suitable material because o f its nature which will not allow plaque accumulation. In the most cases 58 the thickness o f the material was 5-0. Conclusions: In surgical crown lengthening the most used suture material will be the polypropylene with the thickness o f 5-0. The most frequent technique for flap suturing will be the simple interrupted suture, the suture wich will be used not that often will be figure 8 suture.
