What is Polylactic Acid (PLA)?

1. It's a polymer known and used for many years in various medical fields such as Cranio Facial Surgery.
2. It is fully absorbable and bio-compatible with human tissues.
3. Well tolerated and no allergy tests needed.


How does PLA work?

It acts on the subcutaneous tissue and stimulates the activation of fibroblasts and collagen production.


What does the cones look like?

1. It has a 360 degree surface to resist suspension traction and immediately provides strong fixation in the subcutaneous tissue.


Except for suspension traction, what else does the cones do?

1. The fibrous reaction around the cones creates a solid support of the soft tissue, thus preventing risks of migration or extrusion.
2. The foreign body reaction stimulates inflammatory reaction.
3. The cones are slowly degraded by the inflammatory response.
4. A fibrous capsule forms around them in layers and functions as a scar around the knots of the suture.
