Dr. Frank Spear has a course titled “Using Models to Evaluate and Treatment Plan Occlusal Issues”. This course focuses on utilizing dental models to assess and plan the treatment of occlusal issues.

Key Points:

Model Analysis:
Unmounted models: Provide a basic understanding of tooth position and alignment.
Mounted models: Allow for the evaluation of jaw relationships and occlusal contacts.
Facebow Transfer:
Transfers the spatial relationship between the maxillary teeth and the temporomandibular joints (TMJ) to the articulator.
Helps ensure accurate representation of the patient’s jaw position.
Centric Relation (CR) Records:
Record the position of the condyles in the most retruded position of the mandible.
Used to mount the models on the articulator and plan occlusal adjustments.
Muscle Deprogramming:
May be necessary to obtain accurate CR records, especially in patients with muscle tension or clenching habits.
Benefits of Using Models:

Visualize Occlusal Relationships: Models provide a clear 3D representation of the patient’s teeth and jaws.
Identify Occlusal Discrepancies: Models can help identify issues like premature contacts, excessive wear, and misaligned teeth.
Plan Treatment: Models allow dentists to simulate treatment options and predict outcomes.
Communicate with Patients: Models can be used to explain treatment plans and potential outcomes to patients.
Overall, Dr. Spear’s course provides valuable insights into using models as a diagnostic and treatment planning tool for occlusal issues.
