Remount and occlusal corrections in complete dentures

remount procedures for complete dentures are described

1. Good morning….
Remount and occlusal
corrections

2. Specific Learning Objectives
•Understand the principles of occlusal correction
•Identify the indications and contraindications of
occlusal correction:
• techniques of occlusal correction
•Evaluate the outcomes of occlusal correction:

4. SLO

9. Causes of processing errors
1. Failure to close flask completely
2. Too much pressure while closing the flask
3. Dimensional changes during curing
4. Tooth movement during flasking, packing and processing
5. Failure to cool flask before deflasking
6. Distortion due to improper deflasking
7. Expansion of plaster, Shrinkage of acrylic

13. Methods to Correct
•1.Direct Correction
•2.Lab Remount
•3.Clinical remount

20. Lab remount
• Purpose:
•1. To correct errors in occlusion that have occurred
during processing
•2. To return dentures to the correct vertical
dimension of occlusion
•3. To restore centric and bilateral balanced occlusion

21. Laboratory Remount Instruments
and Materials
• Processed dentures intact on master casts
•Articulator and plaster mountings
•Straight handpiece and acrylic burrs
• Quick setting plaster
•Plaster bowl and spatula
•Articulating paper
•Wax spatula

45. Selective Grinding Procedures 
•The intentional alteration of the occlusal surfaces of the teeth
to change their form.
• • Articulating paper of minimum thickness is used for
marking the actual contacts of the teeth.(less than 21 µm thick)
• • The diagnostic adjustment was first made on the casts and
then on the patient using four differently colored ribbons:** 1.
Red: centric stops
•2. Black: protrusive interferences
•3. Green: working side interferences
•4. Blue: balancing side interferences

48. Rules of selective grinding:
•1- Vertical dimension is maintained by occlusion of the
functional cusps which are upper palatal cusps and lower
buccal cusps so never grind from them.
• 2- if it is necessary, we can grind from the inclines of
the cusps.
• 3- We must deepen the fossa rather than removing the
cusp unless, it interferes with the balancing and working
occlusion.
•4- For protrusive movement, we grind from the mesial
and distal surface of the artificial teeth.

50. Conclusion
• Correct occlusal  relationships are a part of the success
in prosthetic treatment for edentulous patients with
complete dentures.
• A clinical remount procedure of the finished dentures is
a constituent part of prosthetic patient treatment in
practice of complete dentures.
•• The laboratory and clinical remount procedures, along
with occlusal corrections, reduces the number of areas of
tissue irritation, post insertion visits, pain during
mastication and swallowing, and discomfort during
mastication, and enhanced the comfort of the patient .

•Have a lovely day and a
fabulous week ahead….
