This type of regenerative surgery depends on guiding the proper tissue to heal the periodontal lesions. Once healed, the gum tissue migrates down into the bone pocket quickly. Unfortunately for the patient, this doesn’t allow time for the bone to refill the pocket, enabling the defect to persist. The predictability of guided tissue regeneration allows time for the bone to fill back in, yielding the best results.
