Fully Digital Workflow for an Immediate Implant-Retained Prosthesis Following Maxillectomy Resection Surgery

This case report aimed to describe a digital workflow from 3D virtual surgical planning for tumor resection, maxillary implant placement, and an implant-retained prosthesis to fit the planned defect for immediate loading. A 68-year-old male was diagnosed with squamous cell carcinoma of the anterior maxilla. Intraoral scans and computed tomographs were taken preoperatively to digitally design and print a surgical resection guide, an implant placement guide, and a prosthetic bridge for immediate placement. The preoperative designed and manufactured prosthesis accurately matched the virtual surgical plan resection and implant positioning. The prosthesis could be placed and fixated for immediate loading. A 3-year follow-up found no locoregional recurrence, stability of the maxillary framework, and implants and prosthesis with a satisfactory aesthetic outcome. This case documents the importance of careful preoperative surgical planning and the opportunities for a fully digital workflow for oral cancer rehabilitation.
