Rehabilitation of marginal mandibulectomy patients using immediately loaded basal implant-supported prostheses

Objectives: To evaluate the treatment outcomes and patient satisfaction following the use of fixed, immediately loaded, basal implant- reconstructive prostheses in a cohort of patients who underwent marginal mandibulectomy. Methods: Ninety-seven Basal Cortical Screw implants (BCS^®1; Dr. Ihde Dental AG, Gommiswald, Switzerland) were inserted in 15 marginal mandibulectomy patients. Clinical, radiographic, and prosthetic parameters, as well as patient satisfaction, were evaluated at 1 week and 3, 6, 9, 12, 18, 24, 36, 48, and 60- months after implant insertion. Clinical evaluations included measurement of the plaque (PI) and modified gingival indices (MGI), and the probable pocket depth (PPD). Implant survival and implant success were assessed using the James–Misch implant health quality scale and the Albrektsson criteria for implant success. Results: The implants showed optimum health with 100 % survival and success rates. None of the implants were mobile, lost, or fractured. There was a non-significant increase in the PI at 3, 6, 9, 12, 18 months, a significant difference at 24, 36, 48, 60-months follow-up visits, and a significant decrease in the MGI and PPD. Radiographic findings showed an increase in bone‒implant contact and peri-implant bone level. Evaluation of the prostheses revealed some manageable complications. All patients were satisfied and reported that they would choose the same treatment modality again. Conclusions: Basal implant- reconstructive prostheses provide optimum clinical and radiographic success, with 100 % implant survival and success rates, and patient satisfaction in marginal mandibulectomy cases.
