Dental Office Visit #4
Try-In
Try-In for anterior esthetic evaluation and modification
When a desirable vertical relationship has been determined with the try-in tooth arrangement, the tracer assembly is opened (or closed) to that same dimension and then employed to record the patient's Gothic Arch Tracing.
An adhesive disc is positioned on the tracing and the top covering is removed to show the tracing .
The clear plastic centric lock disc is positioned with the hole over the apex of the tracing using the positioned needle or by "eye-balling" the hole over the apex.
Quick setting stone or plaster is placed on the buccal sides of the upper and lower assembly, engaging the notches in the wax and entering the open space between the upper and lower assembly. When the material forming the centric locks has set, the tracing assembly may be removed from the mouth.
The materials to be returned to the dental laboratory after these procedures are completed are: the tooth arrangement with any modifications which may have been necessary (tooth positions, vertical dimension opened or closed, etc.), the Gothic Arch tracer assembly with centric locks (the tracing should be made at the same vertical dimension as determined by the try-in tooth arrangement), along with additional specific instructions concerning the tooth arrangement, processing, finishing or another try-in if necessary.
OR....
Try-in for completed tooth arrangement, proper posterior occlusion, and wax contouring detail.
Esthetic considerations at Try-in time:
- Midline harmony with facial features
- Relation of anterior teeth to the lips
- Prominence of canines
- Antero-posterior of anterior teeth
- The occlusal plane (check with Trubyte (Fox) Occlusal Plane Plate)
- Consideration of overall esthetic and phonetic factors
- Vertical dimension
- Centric relation
- Overall patient comfort and acceptance.
