    TAKIjNTG PAKTIAL IMPEESSIOiS^S. (For the benefit of dentists who desire to take partial impressions the following skeleton of ]\Ir. Supplee's method is appended. Such impressions will be found valuable in making models for partial den- tures and for extensive bridgework. Lack of space forbids proper treatment of this subject. Those desiring detailed information are respectfully referred to Mr. Supplee's writings.) The buccal flange is trimmed away from the tray. The impression material is prepared as described for full impressions and is shaped to cover the surface of the hard palate, the lingual surfaces of the remaining teeth and all surfaces of the ridge where teeth are missing. Press the cup home and hold it until the compound has partly set. Remove the tray and compound from the mouth in the direction in which the finished denture is to be removed. Dip the surface of the compound into cold water to slightly chill it; then quickly insert the tray again in the mouth and drive it home with pressure. Cut the margins of comjDound about adjoining teeth to square edges. Shape a roll of compound as for a lower impression and lay it over the labial and buccal surfaces of the teeth. Pull the lip over it,. press the compound in place, allow it to cool. The above steps, if properly followed, obviate the taking of an impression of the bell-shaped necks of teeth, which cannot be used in the finished denture. They make it possible to produce a partial plate which can be inserted into the mouth without trimming.
