Summary
This case report demonstrates a fully digital workflow for oral cancer rehabilitation, enabling precise tumor resection, implant placement, and immediate prosthesis loading. The digital approach ensured accurate fit and satisfactory long-term aesthetic and functional outcomes.
Area of Science:
- Oral and Maxillofacial Surgery
- Digital Dentistry
- Oncology Rehabilitation
Background:
- Oral cancer rehabilitation presents complex challenges, often requiring extensive surgical resection and subsequent prosthetic reconstruction.
- Traditional methods can involve lengthy treatment times and potential inaccuracies in prosthetic fit.
- Advancements in digital technology offer new possibilities for streamlining and improving patient outcomes.
Purpose of the Study:
- To describe a comprehensive digital workflow for managing anterior maxilla squamous cell carcinoma.
- To detail the process from 3D virtual surgical planning to immediate loading of an implant-retained prosthesis.
- To evaluate the efficacy and outcomes of this digital workflow in a clinical case.
Main Methods:
- Preoperative digital planning utilizing intraoral scans and computed tomography (CT) data.
- 3D printing of surgical guides for tumor resection and implant placement.
- Fabrication of a custom prosthetic bridge designed for immediate functional and aesthetic restoration.
- Immediate loading of the implant-retained prosthesis following surgical resection and implant placement.
Main Results:
- The digital workflow facilitated accurate virtual surgical planning and precise execution.
- The designed and manufactured prosthesis demonstrated an accurate fit to the planned defect and implant positioning.
- Immediate loading of the prosthesis was successfully achieved.
- A 3-year follow-up revealed no locoregional recurrence, stable implants and framework, and satisfactory aesthetics.
Conclusions:
- A fully digital workflow is highly effective for oral cancer rehabilitation, optimizing surgical precision and prosthetic outcomes.
- Careful preoperative planning and the integration of digital technologies are crucial for successful immediate loading in complex cases.
- This approach offers significant potential for improving patient function, aesthetics, and overall quality of life after maxillectomy.
