Evaluation of Quality of Life After Mandibular Reconstruction Using a Novel Fixed Implant-Supported Dental Prosthesis...

To evaluate the feasibility and efficacy of a novel concept of early loaded (ie, within 2 weeks) implant-supported fixed dental prostheses (ISFDP) for patients who underwent mandibular reconstruction.

All patients requiring mandibular reconstruction between July 2013 and March 2016 at AZ Sint-Jan Brugge-Oostende AV were screened for dental rehabilitation according to the proposed concept. Of 17 patients, 10 were eligible for inclusion. Clinical and radiologic assessments of implant integration and prosthetic survival were performed at 6, 12, 24, and 36 months. Patient satisfaction was assessed prior to and after prosthetic rehabilitation using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaires Core 30 and Head & Neck 35, as well as a visual analog scale.

Ten patients received mandibular reconstructive surgery for an oral cavity tumor (n = 6), osteoradionecrosis (n = 3), or medication-related osteonecrosis of the jaw (n = 1). Implants were placed within an average of 6 (2 to 21) months postsurgery in a one-stage procedure. Prosthetic rehabilitation was achieved within 2 weeks in 8 of the 10 patients. Two patients received their ISFDP delayed due to postoperative complications. Implant integration and prosthetic outcome at a maximum of 36 months of follow-up were successful in 7 of the 10 patients. At that time, two patients had passed away, while one patient had the ISFPD removed because of graft necrosis after radiotherapy. Patient satisfaction was high, with significant improvement after dental rehabilitation in comparison to mandibular reconstruction alone.

The present concept offers a feasible and fast prosthetic rehabilitation that improves patient quality of life.
