dental help more complicated now occlusion it starts involving molar cross bites it starts involving anterior cross-bite it starts having some dental help components of recession and that fraction present she does have her wisdom teeth there.
So we had to make sure we captured them in the impression or at least the half of them to be able to prevent them from super erupting during the case so now we’d like to see .
How that tracks and follows so let’s go ahead and take a look some photographs and see what we were able to offer Veronica so the first micro stereo perforation technique at the beginning of the case involved .
All these red dots so if you take a look here you’ve got so I did perforations and by this time when we were treating the cases I was being a little more sophisticated and I drew bars across here these rows that you see are basically to show the the thirds of the route and so in the thirds of .
The route I was deciding OK the coronal third of the route versus the middle third versus the apical third you know where did I have opportunity so I started giving myself some so-called depth to give me an idea of where.
I could place my micro steel perforations the depth chart will show you they were all three to four millimeters deep the lower we did perforations on the lower on the upper total for the first round then we get to a liner and so she’s going to be wearing .
These aligners at about a day change again early in the treatment so at a you’re taking away about a third of the treatment time and so what we’re looking at here is a team and here’s the a liner in the upper arch so we’ve got.
A little bit of movement happening and by the time we get to a liner we’re ready for a second perforation and so having a moderate case will offer that to the upper teeth here so we have three and three we have six microns .
New perforations of three to four millimeters in depth the lower arch required less treatment it doesn’t require the extra micro SD or perforations by the time we get to a liner the lower arch is almost done the upper arch
