摘要
Background/purpose: The present study analyzed the subjective responses of patients to surgical placement of dental implants and the subsequent functioning of mandibular implant-retained overdentures as compared with the functioning of conventional dentures. This study sought to ascertain patient satisfaction and long-term effectiveness of tooth replacement with mandibular implant-retained overdentures. %26lt;br%26gt;Materials and methods: Patients (n = 86) unable to adapt to a conventional mandibular complete denture were treated with four one-stage titanium plasma sprayed or sandblasted, large-grit, and acid-etched threaded implants supporting an overdenture retained by a cast bar and extracoronal attachments. These patients were evaluated clinically during periods ranging from 6 months to 12 years. Eighty-three patients provided answers to queries regarding their impressions and feelings both prior to and after treatment for the implant-retained overdentures. %26lt;br%26gt;Results: During the study period, none of the implants or restorations failed. Ninety-eight percent of patients responding to the questionnaire were satisfied with their new overdentures. Retaining and supporting mandibular overdentures with implants yielded improvements in comfort, providing the patients with not only effective oral rehabilitation but also greater self-confidence in social situations. %26lt;br%26gt;Conclusion: The results indicate that mandibular arch rehabilitation by using implant-retained overdenture therapy serves as a predictable and effective treatment protocol.
