Orthognathic Surgery / Orthodontics / Cephalometrics
Participants will learn the practical aspects of cephalometric analysis and surgical treatment prediction for the following session. Participants will gain an understanding of surgical treatment planning in patient with maxillofacial deformity. The discussion will emphasize the surgical techniques (LeFort I, BSSO, and Genioplasty), the supportive orthodontic management and prosthodontic treatment (osseointegrated implants).

Laboratory Session #1:
The Use of Fracture Models and the taking of Dental Impressions

Discussion of alginate, dental stone, plaster, acrylic, wax bite, typodonts, and articulators.

First Exercise:
  1. Take dental impressions of each other with alginate.
  2. Use dental stone to make dental models of each other. Use the clear plastic molds when you pour these models, so they fit into the articulator. When you are finished with this exercise, do not throw these molds away as they will be reused for future courses.
  3. Make wax bite impressions, and mount your own dental models in the articulator with wax bite.
Second Exercise:
  1. Using your own dental models, make an occlusal splint.
  2. Using your own dental models, make a lingual and possible palatal splint, so that you are prepared for your next mandible and palatal fracture.
Third Exercise:
  1. A fracture model of a malunion of a mandible and the corresponding maxilla will be provided. Cut the mandible model to replicate the fracture.
  2. Use the maxillary model, mandibular pieces and modeling clay to reestablish the proper premorbid occlusion. You may need to cut or burr the edges of the model in order to remove corners that interfere with reestablishing the proper occlusion.
  3. Once the proper occlusion is established, stabilize the reduction mandible fracture with a glue gun, and then with plaster.
  4. Mount the maxilla and mandible in the articulator and recheck that you have properly established the premorbid occlusion. It should replicate the occlusion of your typodont, from which the models were originally casted.
  5. Make an acrylic splint.
Fourth Exercise:
  1. Clean up your mess. Remove your models from the articulator. Clean off the plaster from the articulator. Clean off your plastic mold.
