Kerr Endo curettes are extremely sharp and capable of cutting adhered fibers with the efficacy of a scalpel. This allows doctors to provide their patients with the shortest possible recovery time. All curettes are sterilizable and made from the highest quality surgical stainless steel. Ruddle curettes are used to create a deep incision of the periosteal tissue, thereby preventing damage to the tissue. They take into account the undermining of the flap elevation, which, along with the microsurgical incision, constitutes the first two steps of the automatic flap treatment. The rounded or square tips are used to cut and elevate the gingival tissue.
