Mounting in Average Value

A: a. Attach the template holder with the magnetic plate (#46260) to the upper arm of the articulator, and add the flat template (#47740) to it. You can use a rubber band, wrapped around the articulator in the grooves on the legs an occlusal plane indicator for lining up the template vertically. Align the mid-line on the template with the incisal needle. Place the lower model on the template plate. Line up the incisal point of the lower incisals with the mid-line on the plate. Line up the horizontal line with the same place on both 1st molars, just to make sure the model is not twisted. Mount the lower model to the buffer plate with quick-setting plaster. Then bring the upper model into centric occlusion and mount it with plaster.

b. An alternative is to put the incisal needle into the incisal pin, and to place a rubber band around the articulator (in the grooves provided). Then place enough mounting plaster to reach the lower model, and fix the model by hand.

Q: How would you mount models in average value for partially-edentulous patients requiring dentures?

A: Begin the procedure as above, using the template holder and flat template. Set the lower teeth with the incisal edge in contact with the flat plate. Then change to one of the various curved templates (chosen based on the cusp inclination of the manufactured teeth), and mount the teeth to the cusp tip of the canine and lingual cusp of the first pre-molar.

Q: If you're mounting in average-value, what do you use as the condylar inclination on an adjustable articulator?

A: Mounting with the Bonwill Triangle is very close to the Camper Plane, so you use an average value condylar inclination of 30°.

Q: How can you mimic long-centric in the restoration without a centric relation registration (leaf wafer) from the doctor?

A: Choose an articulator that offers a protrusion and retrusion indicator, such as the Artex TR or AR model.
