Upper study model with missing 21/-.

Upper & lower study models in occlusion.

The upper model may be surveyed and blocked out if necessary. However, this try-in was required immediately, therefore a wax base plate is laid on the partial upper study model, without the model been surveyed.

The 21/ - are positioned and gingival margins carved.
