Abstract
Abstract: A technique for obtaining maxillomandibular registration for complete denture patients is presented. The maxillary rim is formed with the use of conventional techniques. The mandibular rim is made from modeling plastic impression compound on a record base formed by the patient into the neutral zone. The mandibular rim then is reheated, and the patient determines the occlusal vertical dimension by swallowing. An imprint of the maxillary rim is made on the mandibular rim at the occlusal vertical dimension. The posterior extent of the mandibular rim is relieved 1 mm. Orientation notches are placed in both rims, and centric relation is recorded with a fast-setting vinyl polysiloxane material. (J Prosthet Dent 2001;85:621-3.)

The anterior stop, similar to that which Wright<ce:cross-ref refid="bib5"><ce:sup>5</ce:sup></ce:cross-ref> describes, allows the operator to concentrate on 1 step at a time.

Uniformly reheating the modeling plastic impression compound occlusion rim is critical for success. If this step is not completed successfully, an incorrect occlusal vertical dimension may result. The use of an anterior stop in the record may introduce error to the procedure because of possible displacement of the record base. When the operator observes that the anterior stop has just made contact with the maxillary wax rim, he or she should instruct the patient to stop closing.</ce:para></ce:section><ce:section id="s0020"><ce:section-title id="st0025">Summary</ce:section-title><ce:para id="p0120">A technique has been presented that allows the practitioner to accurately record the maxillomandibular relationship of a patient.

The maxillary rim is formed with the use of conventional techniques. The mandibular rim is made from modeling plastic impression compound on a record base formed by the patient into the neutral zone. The mandibular rim then is reheated, and the patient determines the occlusal vertical dimension by swallowing. An imprint of the maxillary rim is made on the mandibular rim at the occlusal vertical dimension. The posterior extent of the mandibular rim is relieved 1 mm. Orientation notches are placed in both rims, and centric relation is recorded with a fast-setting vinyl polysiloxane material.
