CR

CR is:

• Physiologically correct

• Biomechanically correct

• Precisely repeatable

• ALWAYS comfortable

• Learnable!

• Only jaw position that reduces occlusal interferences

CR is positional relationship of condylar axis

• Jaw to Jaw relationship with or without teeth bc it's joint position

• Irrespective of vertical distance

  • However, once you open so much and it is more translation, you cut off airway

Most superior position that condyle disc assemblies are also braced medially, thus CR is also mid-most position

Properly aligned in CR can resist max loading by elevator muscle with NO signs of discomfort!

• • Diagnostic criteria for CR
