Abstract
Objective
To assess the feasibility of the use of 3-dimensional (3-D) stereolithographic (SLA) technology in complex maxillofacial reconstructive surgery.
Materials and Methods
3-D SLA technology was used in the treatment planning of complex maxillofacial procedures performed by the Department of Oral and Maxillofacial Surgery at Boston University. Specialized 3-D models were ordered and utilized for surgical treatment of a variety of indications including trauma surgery, temporomandibular joint surgery, orthognathic surgery, secondary correction of facial and skull deformities, and extensive jaw pathology. This technology was also used in one patient for jaw reconstruction using novel bone and tissue engineering techniques.
Results
The use of 3-D models in Oral and Maxillofacial Surgery significantly improved predictability of clinical outcomes when compared to similar treatments without its use. Total operating time was reduced which had the benefit of decreasing the duration of general anesthesia and reducing wound exposure time. They allowed for assessment of extensive traumatic and pathologic defects in three-dimensions prior to surgical reconstruction. The models were also useful in the design and fabrication of custom prostheses, sizing of bone grafts and allowed for manufacturing of scaffolds for bone regeneration.
Conclusions
3-D SLA models can be very effectively used in oral and maxillofacial surgery for multiple indications and diverse clinical scenarios. Successful incorporation of this technology for jaw bone regeneration using tissue engineering techniques offers exciting new prospects for the future.
