Enumerate the principles of suturing
Principles of Suturing are as follows:
- Sutures should always be inserted through the more mobile tissue flap first.
- A circular form of needle is used because of the restricted space in the mouth.
- Suture needles should be grasped only by needle holders and the suture needle should be inserted and pulled through the issue in line with the circle.
- Grab the suture needle in the center with the needle holder.
- Do not grab the needle at the junction of the needle and suture swaged.
- When penetrating through tissues, the needle should enter at right angles to the tissue.
- The goal during suturing multiple tissue levels is to suture periosteum to periosteum and tissue to tissue.
- Pull the suture just tight enough to secure the flap in place without restricting the flap's blood supply.
- The flaps should not be blanched when tying a suture.
- Sutures should be placed no closer than 2 mm to 3 mm from the edge of the flap to prevent tearing through the flap during postoperative swelling.
- Sutures are usually placed distal to the last tooth and in each interproximal space.
