Protein Membranes and Low Level Light Combination Therapy Dramatically Increases Bone Regeneration

Posted on 4 December 2019

The combination of collagen or elastin membranes and low level laser (light) therapy (LLLT) dramatically increases the rate of bone regeneration and healing process post-surgery.

The polymer membranes are promising alternatives in regenerative medicine studies because of their ability to stimulate and support cell proliferation. However, they have limitations that the laser seems to compensate in a significant way.

There was an increase of 20 to 25% in the volume of newly formed bone in the groups receiving the membranes combined with laser therapy compared with the group not treated with the laser. LLLT alone doubles the rate of bone formation post-surgery, compared to the control.

This is by an increase in cell metabolism and fibrin resorption, and a decrease in the release of inflammatory mediators. In addition, LLLT acts as a bio-stimulator by increasing mitochondrial functions and stimulating tissue regeneration.
