c) Tin-foil the model beneath the area of the fracture, and assemble the pieces on the model. Fill in the fractured and prepared areas with baseplate wax, and shape it to the form of the original denture. Half-flask the denture with plaster in the top, or deep, half of the flask, so that the occlusal surfaces of the teeth are about level with the rim. The plaster investment should cover all of the denture except the waxed areas and, when set, should be painted with a separating medium. Fill the shallow half over it, fill the depressed area mix; but, before inverting the deep half over it, fill the depressed area leading to the fracture with plaster to avoid flasking the case.
