Periodontics is the branch of dentistry that deals with the treatment of periodontal disease, i.e., tooth-supporting appliance. Periodontal disease was once considered to be an incurable disease, but today it is accepted that the disease can be kept under the control by applying conservative and surgical treatment methods. Conservative treatment involves the removal of soft plaque, tartar and subgingival concretions and curettage of periodontal pockets.

The basis of surgical treatment of periodontal disease is the flap surgery. Periodontal bone pockets are subject to deep cleaning by surgical access, while the application of bone replacements (Geistlich Bio-Oss®), membranes (Geistlich Bio-Gide®) or enamel growth protein (Straumann Emdogain®) enables the regeneration of bone and soft tissue which results in new strengthening of dangling teeth and healing of tooth-supporting appliance.
