The Di-Lok system, a specially articulated tray is used for precise reassembly of a sectioned definitive cast. The impression is poured, and the cast is trimmed into a horseshoe configuration that fits in the special tray. The tray is filled with a second mix, and the cast is seated. When the stone has set, the tray is disassembled, saw cuts are made on each side of the preparation, and the resulting die is ______.

Articulators are mechanical devices that simulate mandibular movement to make an analysis of functional relationships. Small Nonadjustable Articulators do not have the capacity to reproduce the full range of mandibular movement. Occlusal interferences and associated neuromuscular disorders may ______.

result Signup and view all the answers

Semiadjustable Articulators are about the same size as the anatomic structures they represent. Therefore, the articulated casts can be positioned with sufficient accuracy so that arcing errors are minimal and usually of minimal clinical ______.

significance Signup and view all the answers

An advantage of the arcon design is that the condylar inclination of the mechanical fossae is at a fixed angle to the maxillary occlusal plane. With the nonarcon design, the angle changes as the articulator is opened, which can lead to errors when a protrusive record is being used to program the ______.

Direct fabrication of patterns for extracoronal restorations in the mouth is inconvenient, difficult, time consuming, and next to impossible, practically all wax patterns are made in the dental laboratory. This technique requires an accurate reproduction of the prepared tooth, the surrounding soft tissues, and the adjacent and opposing teeth. A solid cast-and-die system captures the necessary information so the laboratory has all necessary information to fabricate the prescribed restoration. A solid definitive cast (or master or working cast) is a replica of the prepared teeth, ridge areas, and other parts of the dental arch. The die is the positive reproduction of the prepared tooth and consists of a suitable hard substance of sufficient accuracy. The cast must meet certain requirements: It must be an exact reproduction of both prepared and unprepared tooth surfaces. The unprepared teeth immediately adjacent to the prepared tooth or teeth must be free of voids. All surfaces of any teeth involved in anterior guidance and the occlusal surfaces of all unprepared teeth must allow for precise articulation of the opposing casts.
