Upper Study model with missing 1/12.

A Partial upper try-in is fabricated and the try-in and upper model duplicated in the usual method.

A 'blow down' (Duran 2mm or similar) on the duplicated model is performed and the stent trimmed and smoothed as shown.

N.B. An outline of the 'missing' teeth should be seen and if necessary / requested by the clinician, lines drawn vertically to show the desired implant angle.
