Centric interferences can cause erratic contacts on anterior teeth during chewing. Back to
front, front to back. ■

If you remove the premature contacts in posterior and get enough anterior space to restore
the anterior due to the AOB caused by CR, you probably won't have to restore the posterior. If
you increase the VDO first, you have to restore every tooth. ■

Turns out there is very little centric slide in this case (back), but what about the condylar
pathway? Nothing has been mentioned about that. Using check bites the condylar inclination
angle is 25° bilaterally.
So what does that mean for the linguals of the upper anteriors? A time-tested philosophy has
developed that suggests anterior guidance should be consistent with condylar guidance. (I can
post citations, if you want.) This will create a more ideal envelope of motion, and when coupled
with a stable seated centric, an ideal envelope of function.
Here's what her anterior angle of disclusion is:

Think of the mechanics at play here. So, what to do?
Start waxing in this case, rather than open the VDO.
And the lower anteriors needed to be restored for aesthetics, and from the gingival levels it did not appear
there was much dentoalveolar extrusion. I elected to
"reshape" them for now and see what I could accomplish
with wax. ■
