1. RULES OF SELECTIVE GRINDING
FINISHING AND POLISHING OF DENTURE

2. Supporting or Centric Holding Cusps
* The vertical
dimension of occlusion
is maintained by
occlusion of the palatal
cusps of the maxillary
teeth & the buccal
cusps of the mand.
teeth.

3. Rules of adjustment a- If the cusp is high in centric & eccentric
positions. Reduce the cusp.
b- If the cusp is high in centric & not in eccentric
positions. Deepen the opposing fossa or
marginal ridge.

6. eliminated in the centric & eccentric positions:
* After all interceptive contacts have been
eliminated in the centric & eccentric positions:
a- Don’t reduce the maxillary palatal cusps or the mandibular buccal cusps.
b- Don’t deepen the fossa or marginal ridge

7. II- Occlusal Balance in Lateral Excursion
(B.U.L.L RULES)
* Rules of Adjustment
**** working side
**** balancing side

10. III- Selective Grinding for Protrusive Balance
* In protrusive balance, the anterior teeth
should make incisal edge contact at the
same time that the tips of the buccal &
lingual cusps of the posterior teeth contact.

12. Rules of Adjustment a- If the anterior teeth have heavy contact
with no posterior contact:
* Reduce the labio-incisal surfaces of the mandibular teeth & the palatal surfaces
of the maxillary teeth.

13. b- If the posterior teeth have heavy contact with no anterior teeth contact.

14. and selective grinding, the operator should check the following:
* After finishing the laboratory remounting
and selective grinding, the operator should
check the following:
1- Clearance at the heals.
2- Accuracy of reproduction of the vertical dimension of occlusion.

15. 3- Simultaneous contacts of posterior teeth
in centric occlusion.
4- Excursive clearance from centric
position ( bilateral balanced occlusion )

16. Clinical Remounting
* It consists of remounting the finished denture on an articulator by using
interocclusal records in the patient’s mouth
* The occlusion is then adjusted on the
articulator to remove discrepancies &
interferences.

20. Centric Interocclusal Record
* The centric interocclusal record is used to mount the
mandibular denture on the articulator as a part of the clinical remount & selective
grinding procedure.

22. Advantages of clinical Remounting
1- It reduces patient participation.
2- It permits the dentist to see better what
he is doing.
3- It provides a stable working foundation;
denture bases are not shifting .

23. 4- The absence of saliva makes possible
more accurate markings with the
articulating paper.
5- Corrections can be made away from
the patient .
