Presenting |
| • |
Point out the condyle is not fully seated (is not in centric relation). |
| • |
Point out how opposite muscles have to be tense (contracted) to hold the condyle on the slope of the eminence (in a sense they are "at war"). |
| • |
Show that as the condyle goes to CR the lateral pterygoids release. |
| • |
Explain that this motion will lead to tooth sensitivity, wearing, looseness, fracturing and breaking. |
| • |
Click the Loop button down, then click the Play button to have the bruxing occur continually - just as it will when the client is asleep. |
