title: The multiple cantilever system: a solution for a failed precision attachment denture case.
abstract: Multiple-cantilevered pontic bridges can be a great alternative to dental implants and distal extension prostheses. Dental hygiene must be considered the most important factor in preserving the status quo of the permanent restoration. Traumatic occlusion, which can occur because of the widened periodontal space and greater mobility of a multiple-cantilever bridge, is not automatically a sign of failure. As long as the mobility of the fixed bridge does not increase and the patient can function and feel comfortable with it, a successful therapy can be concluded. If marginal periodontitis exists, destruction of the cervical ligaments, bone resorption, and apical migration of the epithelium will occur. Through loss of the supportive structures, hypermobility will increase. If the destructive factors of marginal periodontitis are not eliminated, the hypermobility can interfere with masticatory function. It is important that patients be made aware of this possibility. Regular recalls in the beginning of the maintenance program will emphasize the importance of the home-care system.
