Grinding guidelines
1 Verifying centric contacts:
In complete denture prosthetics, it is generally not
recommended to perform major occlusal adjustments
prior to processing the denture base.
Correct increases in vertical dimension prior to
removing the polymerized dentures from the model.
Make sure the centric lock is engaged.
Occlusal adjustments should be performed using the
following guidelines:
• Do not adjust the working cusps.
• Reduce premature contacts in the antagonist fossa.
After adjusting the occlusal height, re-establish all the
centric contacts as determined by the setup.
2 Adjusting functional movement:
Relatively large guiding contacts are desirable to ensure
a balanced occlusion within the functional range.
The following adjustment guidelines are recommended:
•
Centric contacts: do not adjust
• Working side (laterotrusion): adjust mesio-buccal
cusps in the maxilla and lingual cusps in the mandible
• Non-working side (mediotrusion): adjust mesio-
buccal cusps in the mandible
• Protrusion: adjust disto-buccal cusps in the maxilla
and mesio-buccal cusps in the mandible
• Retrusion: adjust mesio-buccal cusps in the maxilla
and disto-buccal cusps in the mandible
The incisal edges of anterior teeth should be ground
from the palatal side in the maxilla and from the labial
side in the mandible, in accordance with the wear pattern
occurring in the natural dentition.
