16. Bruxing Sideways: Effect on Canine/Molars |
| • |
Grinding of cuspid (canine) developing to back tooth wear, recession and abfraction |
|
|
| |
|
| |
Purposes |
| • |
Show that canine bruxing breaks down anterior guidance, leading to problems with molars including recession, looseness, wear, cracks and abfractions. |
| • |
Illustrate that the recessions and abfractions we see at gum lines are not only from brushing teeth too hard but from flexure and repeated bending. |
| |
|
| |
Presenting |
| • |
State how the front teeth have longer roots in general than the back teeth, and experience smaller forces as they are further from the fulcrum. |
| • |
Explain that possibly when searching for a centric bite, nervous habits, or stress, we can also wear down our front teeth - shown in an accelerated manner in this animation. |
| • |
When the front teeth wear down, anterior guidance is lost. |
| • |
Back teeth can now experience sideways forces that they do not bear well, so they are loosened. |
| • |
Teeth can also bend slightly by these forces causing abfractions where the hard enamel of the crown meets the softer cementum of the root. |
| • |
Photos illustrate how abfractions can also occur in the front teeth when they are experiencing bruxing. |
