What is the role of a periosteal elevator in periodontal surgery?

The role of a periosteal elevator in periodontal surgery is primarily to detach tissues from the bone and elevate flaps. This instrument is crucial during surgical procedures, as it allows the surgeon to reflect soft tissue away from the underlying bone, creating a clear view and access to the surgical site. By using a periosteal elevator, the clinician can carefully separate the periodontal tissues from the bone without causing significant damage to the surrounding structures, facilitating a successful surgical intervention.

The use of a periosteal elevator contributes to both the effectiveness of the surgery and the preservation of tissue health, which is critical for postoperative healing. Understanding this tool's specific function highlights its importance in techniques that require access to the root surfaces and alveolar bone for effective treatment of periodontal disease or for performing soft tissue grafts.
