title: Modified flasking technique for processing a maxillary resection obturator with continuous pressure injection.
abstract: It is not possible for the wax pattern of most large-volume maxillary resection obturators to be placed into a flask for conventional compression molding processing and positioning of the wax pattern. However, these wax patterns and their channel access design often can be modified and aligned in position for processing with the continuous pressure injection technique. This article describes the use of the continuous pressure injection technique to process the perpendicularly aligned wax pattern of a maxillary resection obturator. It also describes a modified channel design and a simple method to pull back the injection funnel to increase the volume of the flask.
