Condylography: recording and analysis
Condylography: recording and analysis
Course overview
This is a course on condylography in the concept of Rudolf Slavicek!
What you will learn
prepare a patient for the mandible movement recording
determine the hinge axis and the reference position of the patient
make a decision if the exact splint position works
follow the standard protocols for mandible movements recording
identify errors and artifacts during the recording
describe the data received from the condylography.
The course is for prosthodontists, orthodontists and functional dentists.
