This power point presentation is an half and hour presentation covering basic materials used, classfication and commonly used techniques, knot tying, and suture cutting. Very efficient for dental students.

1. SUTURE
MATERIALS
AND
SUTURING
TECHNIQUES
Dr. Amit Agrawal

2. What is a suture?
Suture is a stich or series of stiches made to secure apposition
Of the edges of a surgical or traumatic wound.
What is a suture material ?
It is an artificial fiber(s) used to keep wound together until they
hold themselves.

3. Goals of suturing
• Wound edge apposition
• Provide adequate tension
• Maintain hemostasis
• Aid in wound healing
• Avoid wound infection
• Produce aesthetically pleasing scar by approximating
wound edges.

21. Knot
Components of a knot.
1. LOOP: created by knot.
2. KNOT: itself, which is composed of a
number of tight throws.
3. EARS: which are the cut ends of the suture.

22. Types
Of
Knots

24. Suture Removal
All sutures being foreign bodies cause irritation to the
tissues and hence have the potential to cause scarring or infection.
Non-absorbable sutures are best removed after a period of 7-8 days.
The suture area is cleaned with saline and the suture thread is lifted above
The epithelium surface.
The suture is cut as close to the tissue as possible, to avoid dragging the
contaminated suture materials through tissues.
The suture is then pulled towards the incision line to prevent dehiscence.

25. Reasons for failure of sutures
Breakage
Cuts out
Knot slips
Extruded suture
Resorbs too rapidly
Removed too early.
