3. CAUSES OF FAILURE TO PROVIDE AND
MAINTAIN ADEQUATE OCCLUSION ON
THE REMOVABLE PARTIAL DENTURE
1. Lack of support for the denture
base.
2. Establishing occlusion in a single
static jaw relation record.
3. Unacceptable occlusal plane.

4. • The influence of the remaining
natural teeth is usually such that the
occlusal forms of the artificial teeth
must be made to conform to an
already established occlusal pattern.

10. RECORDS OF OCCLUSAL RELATIONSHIPS FOR
PARTIALLY EDENTULOUS PATIENTS
• Direct apposition of casts.
• Interocclusal records with posterior teeth
remaining.
• Occlusal relations using occlusion rims on
record bases.
• Jaw relation records made entirely on
occlusion rims.
