When plaque and calculus are not removed the bacteria in plaque produce toxins (or poisons) that can destroy the supporting tissues and bone around the teeth. As the diseases progress, the gum around the tooth becomes loose and separates away from the tooth resulting in deep areas called pockets. As these pockets deepen, more gum tissue and bone are destroyed forming deep bone defects.
Are bone substitutes (powders/ gels/ sponges) etc., which are placed in the diseased areas to enhance new bone formation with application of regenerated techniques.
Various Bone Graft materials available in hospital are: Osteogen, Biogran, Perioglas, Fisiograft ( gel /sponge).
