This lecture examines why it is often necessary to mount models, but also goes into detail on when the extra effort is not worth the time.

  • Hand mounting doesn’t show what happens in all parts of occlusion
  • Mount in centric relation
  • Just because you mount in CR doesn’t mean that is where you will restore, but it will allow you to see all occlusal contacts
  • Only mount when occlusion is pathologic/ failing (wear, TMD), or significant amount of restorative dentistry, or if wax up is needed.
  • Mounting models shows what we can expect with different occlusal patterns
  • Can create a template for equilibration, tooth preparation, temporization
  • Helping to decide what is the best modality for treatment. Should orthodontics be involved? Does that patient need orthognathic surgery?
  • Replicate functional movements of the patient
  • Transfer esthetic information that can be useful for diagnosis and treatment
