Set up

The set up is the best test for the diagnosis. It consists in divide and relocation the teeth of the models. 

There is a lot of ways to do it like for example by computer programs in 3D or the manual way. Here in school they prefer to do with our hands, it takes for 4 hours more or less. 

First of all we need to plan witch teeth we are going to remove for a good occlusion Class I. We want to remove all the first premolar so we can have space for all the teeth. 

We need to make two holes. The first one under the second premolar and first molar. The second hole is under the two central incisors. 

We introduce hacksaw between the holes. 

Finally we are going to have 5 teeth in total for the first part. We have to divide teeth by teeth without destroying the contact point. Then we start mounting the teeth with wax without the first premolar. That's very important.  

And like this, we continue.
