Abstract
BACKGROUND: The timing of placement as well as the functional benefit of interforaminal implants in edentulous patients treated for oral cancer is unclear. METHODS: Fifty-six patients were recruited at 2 institutions. In 1 institution, interforaminal implants were placed during ablative surgery, the other institution used conventional prosthodontics with optional placement of implants postsurgery (postponed-placement). Masticatory performance, bite force, and subjective masticatory function were assessed before and 6 months, 1 year, and 5 years after surgery. RESULTS: Implant-retained overdentures (IODs) demonstrated the highest bite force and the least problems with solid food and food choice. Masticatory performance was equal for IODs and conventional dentures. After 5 years, IODs from patients in the during-ablative-surgery cohort tend to have higher bite force and masticatory performance than those from patients in the postponed-placement cohort. CONCLUSION: IODs produce the highest overall masticatory function. Implant placement during ablative surgery seems to be functionally beneficial.
