Abstract:
The use of patient specific prostheses in Oral and Maxillofacial Surgery
The use of Patient Specific Prostheses in Oral and Maxillofacial Surgery (OMS), along with Virtual Planning have become the standard of care in all fields of OMS, including Oncology,
Orthognathic surgery and TMJ Reconstructive Surgery. Implementation in facial trauma surgery, is the next challenge with in-house manufacturing to be implemented in the future.
Maxillofacial Oncological Surgery creates great challenges for patients, it is potentially mutilating and morbid, with the resection of both tumour tissues and normal tissues to create an adequate surgical margin to enable cure. Free tissue transfer is the standard for reconstruction, the bone flaps must be sculptured and fitted along with their soft tissue pedicles and adequate soft tissue to replace and repair the surgical defects. Modern radiology including Computed Tomography integrated with Angiography shows the tissues and their blood supply, enabling the design of more complex reconstructions. The reconstructions must be 3 dimensionally formed and fixed in situ to the residual bone stock. This is the role for patient specific implants, reconstruction plates that are virtually designed by surgeons and engineers working together. A new innovation is combining this planning with the use of conventional dental implants to reconstruct the dentition.
Congenital, acquired facial deformities and temporo-mandibular joint (TMJ) pathology cause significant functional and self-esteem issues for patients. Congenital facial deformities such as clefts can be managed with corrective jaw surgery (Orthognathic surgery). TMJ reconstruction has been greatly advanced in the last decade with total joint replacement / reconstruction with prosthetic replacement. Both orthognathic surgery and TMJ reconstruction are now being done with virtual surgical planning and patient specific implants. This has led to significant improvements in outcomes and reduction in morbidity. This part of the presentation will highlight the advantages and pathway of planning and delivery of the prosthesis using recent Melbourne cases.
