Mandibular/Maxillofacial Orthognathic Surgery
Orthognathic surgery cases following trauma or congenital disease can be more easily planned using models. Issues such as symmetry, projection, and volume can be better visualized using a model. Implants and reconstruction plates can be pre-bent before surgery, allowing for a better contour and shorter surgical procedure.
Three dimensional analysis of the temporomandibular joint using anatomical modeling has proven an invaluable aid for surgeons treating TMD. For cases of severe joint degeneration, stereolithography models can be used for the creation of custom-fit partial or total joint replacement.
Pre-surgical implant placement through the use of 3D modeling has proven to be an excellent tool and superior to using stone models. Giving you a clear and precise representation of the location of vital anatomy surrounding the implant, 3D modeling provides you with the information you need in the palms of your hands.
Use of a model in planning distraction osteogenesis procedures has proven to help answer questions relating to the type of distraction device used, the size of the device, and intraoral versus external device type. Additionally, the model can save operating time by allowing precise pre-bending before surgery, taking into account the vectors of distraction and vital structures, such as teeth buds and the inferior alveolar nerve.
Cases for reconstruction of congenital disease in pediatric patients have been a good indication for the use of models. Procedures such as cranial vault remodeling, resection/reconstruction of fibrous dysplasia, and midface advancement all benefit from the use of a model preoperatively for surgical time savings and enhancement of outcomes.
Frequently Asked Questions
Medical Modeling is a procedure during which a highly accurate physical model can be made from medical imaging modalities such as CBCT. Sophisticated software is used to view and extract information to create a virtual 3D model of a patient’s bone structure. After the virtual model is created, the digital file is then sent to a rapid prototyping machine to produce the final model in physical form. Complete models are then measured and checked for accuracy.
It has been our mandate since CBCT was first introduced to the dental community that every scan be read by our Oral and Maxillofacial Radiologists. This alleviates any chance of an abnormality or pathology going undetected.
Yes. Most medical models are clear, so areas of interest–such as a cyst or tumor, the TM joints, or the alveolar nerve–can all be indicated in the model with a different color as specified.
