Multifilament silk thread

Silk Suture is produced from silkworm larvae and contains fibroin protein in its structure. Its advantages have set standards for other sutures. Silk is a natural, non-absorbable suture material widely used for wound closure. It is the most common natural suture, surpassing collagen, and has been used in the biomedical industry for over 100 years.

Silk is easy to handle, has excellent knot-tying properties, and has a very low risk of allergic reactions. Although silk sutures are considered non-absorbable, they gradually degrade and disappear within two years.

Its soft structure provides comfort for patients. One disadvantage of silk sutures is that they tend to become embedded in the cells around the sutured tissue, making removal difficult and painful. However, silicone-coated or specially waxed silk sutures are available to limit capillary penetration. They are often used for suturing mucosal tissues or closing areas between tissues. Silk is also useful as a temporary suture during surgery due to its easy handling.

Silk sutures are available in multifilament and monofilament forms and can be used for tissue closure in dentistry, gastrointestinal surgery, ophthalmology, oral surgery, and obstetrics.

Silk sutures can also be used as ligatures for permanent fixtures, removable fixtures, and cardiovascular surgery, including graft suturing. As a suture material, silk is non-absorbable and is not recommended for urological procedures because it may facilitate stone formation around the suture, a characteristic associated with non-absorbable materials. In addition, it should not be used in infected or infection-prone areas. One of the main disadvantages of silk sutures is their poor resistance to microbial activity.
