Study Notes

Premature Contact

Maximum reduction is necessary if the maximum is in premature contact in the central relation and also in equilibrium or working.
Premature contact in the central relation, equilibrium, or working indicates the need to reduce the maxima.

Centric Prematurity

If the cap is in premature contact in the central relation but not in equilibrium or working, adjustments are necessary.
Adjustments involve the corresponding fossa or the balance side if there is premature contact.
Adjust the buccal level inclined from the lingual edge of the first maxillary tooth or the level of lingual ingress of the buccal end of the mandible (tooth).
Avoid adjusting both the upper and lower teeth.
Preserve the central grasping cusps by not adjusting the tip of the rim.

Cantilever Walk

Premature contact in a cantilever walk (L-shape) requires adjustments to achieve the desired connection (M-shape).
Adjust the distal proximal slopes of the upper teeth to achieve the desired connection.
Alternatively, adjust the median slopes of the lower teeth to achieve the desired connection.
