- 4. SIGNIFICANCE OF SIZES Sutures are numbered from sizes 1-0 to 9-0 Greater the number of sizes,the thinner the material Thick sutures are used for approximation of deeper layers, wounds in tension prone areas and for ligation of blood vessels. Thin sutures are used for closing delicate tissues like conjunctiva& skin incisions of the face. 5-0&6-0 generally used for skin closure in head & neck. 3-0&4-0 are used intraorally www.indiandentalacademy.com
- 5. PRINCIPLES OF SUTURING The needle should be grasped at approximately 1/3rd the distance from the eye& 2/3rds from the point. The needle should enter the tissues perpendicular to the tissue surface. The needle should be passed through the tissues along its curve. The suture should be passed at an equal depth&distance from the incision on both sides. The needle should always pass from the movable tissue to the fixed tissue. The needle should always pass through the thin tissue to the thick tissue. www.indiandentalacademy.com
- 6. Tissues must never be closed under tension,undermining the tissues must be done prior to suturing in such cases. The suture should be tied only to approximate the tissues,not to blanch. The knot should never lie on the incision line. Sutures should be placed at a greater depth than the distance from the incision so as to evert the wound margins. Skin sutures are removed in 5 days& intraoral sutures in 7 days. www.indiandentalacademy.com
