When the goal of restorative treatment is to maintain the patient's preexisting intercuspation and occlusal vertical dimension (OVD) following tooth preparation for crowns or fixed partial dentures (FPDs), casts must be mounted on an articulator in the same pretreatment tooth-to-tooth relationship. A simple technique is described that uses acrylic transfer copings over prepared teeth to record and preserve this relationship so that working and opposing casts can be mounted accurately. The technique may be used to recapture the lost third leg of the tripod after teeth have been prepared. To further reduce errors when mounting casts onto an articulator, a method is recommended that uses rigid connectors to join and stabilize casts in a manner that minimizes potential movement during placement and setting expansion of gypsum mounting materials.

UI	MeSH Term	Description	Entries
D007574	Jaw Relation Record	A registration of any positional relationship of the mandible in reference to the maxillae. These records may be any of the many vertical, horizontal, or orientation relations.

D003725	Dental Articulators	Mechanical devices that simulate the temporomandibular joints and jaws to which maxillary and mandibular casts are attached. The entire assembly attempts to reproduce the movements of the mandible and the various tooth-to-tooth relationships that accompany those movements.

D003761	Dental Impression Technique	Procedure of producing an imprint or negative likeness of the teeth and/or edentulous areas. Impressions are made in plastic material which becomes hardened or set while in contact with the tissue. They are later filled with plaster of Paris or artificial stone to produce a facsimile of the oral structures present. Impressions may be made of a full complement of teeth, of areas where some teeth have been removed, or in a mouth from which all teeth have been extracted.

D003766	Dental Occlusion	The relationship of all the components of the masticatory system in normal function. It has special reference to the position and contact of the maxillary and mandibular teeth for the highest efficiency during the excursive movements of the jaw that are essential for mastication.
