Long-term results of endosteal implants following radical oral cancer surgery with and without adjuvant radiation therapy.

摘要: Purpose: The aim of this study was to analyze the long-term survival implants and implant-retained prostheses in patients after ablative surgery oral cancer with or without adjunctive radiation therapy. Materials Methods: Between 1997 2008, 66 who had undergone tumor cavity were treated dental (n = 262). Thirty-four received therapy daily fractions 2 Gy administered on 18 30 days. Implants inserted maxilla (49; 18.7%) mandible (213; 81.3%), non-irradiated residual (65; 24.8%) grafted bone (44; 16.8%) irradiated (15.6%) (39; 14.9%). Seventeen fixed protheses 53 removable dentures (34 bar attachments, 9 telescopic 10 ball retained dentures) inserted. Results: Mean follow-up implant insertion 47.99 (±34.31) months (range 12–140 months). overall 1-, 5-, 10-year rates all 96.6%, 86.9%, respectively. Fourteen lost nine (5.3% implants); eight primary losses, five secondary losses because an operation recurrence. There no significantly lower for into (p = .302), and/or soft-tissue grafts (p = .436), (p = .563). All prosthetic restorations recurrence could be maintained during observation period. Conclusions: Implant is not influenced by therapy, (bone soft tissue), location (maxilla mandible). However, placed exhibit a higher failure rate healing period than those bone. No superstructure particularly favorable. Osseointegrated can used successfully prior history additional therapy.
