Abstract
Biomaterials are disclosed comprised of biodegradable, biocompatible, and bioabsorbable composite membranes for use in surgery for the guided regeneration of tissues. The composite membranes are comprised of threads embedded in a matrix, wherein both the matrix and the threads can be comprised of esters of hyaluronic acid, used singly or in combination, or esters of hyaluronic acid in combination with esters of alginic acid or other polymers.
