8. Positioning of non-articulated occlusion models
You have various options for inserting an occlusion model into the scanner. The easiest method for non-articulated
occlusion is to fasten the occlusion model to the object holder with knurled screw using a rubber band.
The flexible object holder is not suitable for this purpose.
Alternatively you can use an occlusion clamp.
For articulated occlusions you require an articulator.
8.1. Fastening an occlusion model with a rubber band
OBSERVE THE SAFETY INSTRUCTIONS!
To fasten the upper and lower jaw in occlusion, you require a conventional rubber band of approx. 0.4 cm width and
approx. 8.5 cm diameter. Alternatively you can use a crossed band. The length and strength of the rubber band varies
depending on the jaw model. For this reason, always keep several different rubber bands available.
Rubber bands are not included in the optional scanner accessories. For safety reasons, use only new, robust rubber
bands and replace these regularly.
•
Place the upper jaw model on the lower jaw model in occlusion.
•
Place the rubber band in cross form so that the top part of the upper jaw model so that an equally long loop hangs
from each side.
•
Guide the end of each rubber loop around the hooks on the side of the object holder.
The fastening is adequate if the upper jaw model cannot be tipped or
shifted with slight pressure.
If necessary, shorten the rubber bands by coiling over the hooks
several times.
Alternatively, you can use two shorter rubber bands or a crossed
band. Depending on the length and strength of the rubber bands
used, alternative fastening methods are possible, e.g.:
•
Place two shorter rubber bands at an angle over the jaw model.
•
Guide one end each at the front and rear around one of the hooks
on the side of the object holder.
If you are using a crossed band, you can only secure the jaw
models to the object holder in occlusion.
•
Place the crossed band around the jaw models in occlusion such,
that one crossed part is on the top and one on the bottom and
that the two partial bands are stretched on the side.
•
Secure the connected jaw models on the object holder.
•
Guide the laterally stretched rubber bands around the hooks on
the object holder.
