15. Bruxing: Effect on Molars |
| • |
Grinding motion causing tooth to be moved. |
|
|
| |
|
| |
Purposes |
| • |
Show that bruxing motion, applying offvertical forces that molars are not designed to withstand, will loosen, crack and wear teeth. |
| • |
Loosening can be front-to-back, side-to-side, and up-and-down. |
| • |
Provides opportunity to explain why bone loss can occur in the absence of pockets i.e. healthy sulcus, normal probing depth but class three mobility. |
| • |
This is why we observe the widened periodontal ligament space on x-rays. The bone is supposed to be in intimate contact with tooth roots and the pdl space should be microscopically thin. |
| |
|
| |
Presenting |
| • |
Show the teeth contacting laterally not vertically. |
| • |
Just as a fencepost would loosen if repeatedly hit by a pickup truck as opposed to having the kids sit on its top, so it is with the vertical bone loss we see in our clients' mouths. |
| • |
As with other bruxing animations, click the Loop button down, then click the Play button to have the bruxing occur continually.
|
| • |
The lateral movement softens the bone which then allows the tooth to move vertically. |
