Dental Office Visit #3
Occlusal Registration
Contour the maxillary occlusion rim and mark the patient's midline
The maxillary occlusion rim should support the upper lip and the facial-incisal edge of the contoured occlusion rim should contact the vermillion border of the lower lip when the patient repeats fricative ("f") sounds.
Define occlusal plane using the mxillary occlusion rim.
The patient's vertical dimension and occlusal plane is established during these procedures. The Trubyte (Fox) Occlusal Plane Plate is an excellent aid in determining the most desirable occlusal plane for the patient. The relationship of the Trubyte (Fox) Occlusal Plane Plate should be used to confirm that the maxillary occlusal plane when viewed from the anterior parallels the plane which passes through the center of the patients pupils when the patient is standing or sitting erect. When viewed sagitally, the maxillary occlusal plane should parallel the plane which contains the patient's Ala-Tragus line when the patient is standing or sitting erect.
Establish preliminary centric relation
The preliminary centric relation registration should be as accurate as possible. The occlusion rims should index accurately to be secured together.
Determine closest speaking space and recording preliminary centic relation
Prior to recording the preliminary centric relation, contour the mandibular wax occlusion rim such that it is parallel to the maxillary occlusion rim when the patient speaks sibiliant ("s") sounds. The occlusion rims should closely approximate each other but should not contact even when the patient counts quickly from sixty to seventy. The contour of the mandibular occlusion rim should be such that it does not interfere with lip and cheek position during speaking or swallowing and does not interfere with the tongue during speaking.
Record the maxillo-mandibular relationship at the occlusal vertical dimension.
Index the posterior aspects of each wax occlusion rim and encourage the patient to close until the rims contact with their mandible retruded as far as possible. Record this closed position using wax or a polyvinyl siloxane registration material such as "Regisil.
Select Trubyte Teeth
A preliminary centric relation registration, along with complete information regarding moulds, color, and type of teeth, as well as a desired tooth arrangement is then transferred to the dental laboratory.
