Restoring faces and changing lives


Patients who have suffered traumatic injuries to the facial area as a result of for example gunshot wounds, motor vehicle accidents or fires, often require prostheses to replace missing areas of bone or tissue. In the case of head and neck cancers, patients may require major surgery to remove tumours that would otherwise be life-threatening. Unfortunately this surgery can sometimes be so extreme that facial tissue or bone is lost in the process. Furthermore, owing to the nature of these tumours, chemotherapy and radiation can cause further damage to facial tissue, which may have an effect on the patient’s ability to function normally.


Maxillofacial prosthodontic surgery offers hope to these patients by restoring oral functions such as swallowing, speech and chewing, or by providing aesthetic restoration in cases where facial features such as ears or noses have been damaged.

The Department of Prosthodontics in the School of Dentistry at the University of Pretoria (UP) is one of only a few centres in the country where specialised maxillofacial prosthodontics services are offered to state patients. The Maxillofacial Prosthodontics Project, which is run by staff in the Department, is multidisciplinary in nature and includes the services of a team of specialists consisting of maxillofacial surgeons, plastic surgeons, ear, nose and throat specialists, and in cases involving patients suffering from cancer, oncologists and radiotherapists. As part of an extended rehabilitation programme after surgery, the services of a speech or language therapist may also be enlisted.


The restorative work undertaken by the team to date has included implanting jaw prostheses, manufacturing dental prostheses and obturators (which are dental prostheses used to seal openings in the palate, such as is needed in babies with cleft palates) and constructing extra-oral appliances such as prosthetic eyes, ears and noses. Regular follow-up treatments for maintenance or replacement of prostheses due to normal wear and tear, or in some cases due to the changing shapes of the defects after healing or following recurrences, are an integral part of the service offered by the team.

Current research in the Department includes investigations into advances in the use of computer-aided treatment planning. This technology will enable surgeons to better plan the best course of treatment and could potentially minimise the number of times a patient has to go under the knife for complex surgeries. Closely related to this is research in 3D framework design and fabrication of prostheses, rapid prototyping and 3D printing, as well as the design of new materials that can be used in the manufacturing of prostheses.

The work done by the team at the Department of Prosthodontics draws from many different academic disciplines, but the overarching goal of the surgical work they do and the research they undertake remains to effect a lasting change in the lives of the patients they treat.
