| 摘要 |
The reabsorbable hybrid device for guided tissue regeneration describes an absorbable, implantable synthetic membrane designed for use as a biological barrier in guided tissue regeneration (GTR) procedures in the treatment of periodontal and bone defects, which forms a biological barrier composed of poly(lactic-co-glycolic acid) copolymers that acts as a matrix, and a second phase that acts as filler and/or biological inducers; and the copolymers that form the matrix are completely diluted in organic solvent followed by the addition of the additional compounds of the second phase (filler), as required, in various concentrations in accordance with use, potentially ranging from 0.0001% to 99.9999%. |
