Clinical evaluation of swinglock removable partial dentures

Fifty-three patients were recalled for clinical examination to determine oral changes which occurred during the time that they wore swinglock removable partial dentures. Pertinent findings were as follows: 1. The swinglock removable partial denture should be considered as a treatment alternative for patients with unfavorable periodontal support and for patients missing key abutments. 2. Patients who have worn swinglock removable partial dentures for periods of 13 to 75 months did not demonstrate a continued periodontal breakdown, even when there was unfavorable periodontal support. 3. The swinglock removable partial denture may aid in reducing tooth mobility when the patient can maintain good levels of oral hygiene to control inflammation and the dentist can provide a proper occlusion. 4. As evidenced by responses to a satisfaction questionnaire, patient acceptance of the swinglock design was good. 5. The high prevalence of patients reporting for recall examination with one or more decayed teeth (22.4%) and removable partial dentures requiring relines (28.3%) emphasizes the need for proper recall of patients. 6. The swinglock removable partial denture will function satisfactorily if the dentist follows basic principles of removable partial denture construction and if the patient maintains a good level of oral hygiene and returns for regular recall visits.
