• Masticatory function of a muscle depends on
the skeletal muscle force and co-ordination of
orofunctional movements.
• Skeletal or biting force decreases with age.

• Chewing efficiency
decreases as the no. of
natural teeth reduces.
• CD patients- 7 times
more chewing stroke.

1. Evaluation of Intaglio surface
• For undercut areas and
accuracy of tissue
contact.
• Pressure disclosing
paste.
• Path of insertion.
company 1992.(Pg. no. 391)
86

• Severe bony undercut relieve – prevents
stripping.
• Exostosis or midpalatal raphe.
• Occlusal harmony
• Smoothen.
87

2. Evaluating the borders and
Cameo Surface
(i) The border extensions
and contour are
compatible with the
available space in
vestibules.
88

(ii) Frenum attachment
and hamular notch area.
(iii) Dentures are stable
during speech and
swallowing.
company 1992.(Pg. no. 393) 89

• Disclosing wax.
• Relieve overextension if
present.
company 1992.(Pg. no. 393) 90

3. Clinical errors
a. Errors in registering the Jaw Relation:
i. Inaccurately fitting record base.
ii. Shifting of record base over displaceable tissue.
iii. Excessive pressure by patient.
iv. Unequal distribution of stress.
v. Record base placed on deformed soft tissues.
vi. Patient not registering centric relation.
company 1992.(Pg. no. 394) 91

b. Errors in mounting cast:
i. Record base not properly secured to cast.
ii. Occlusion rims not definitely locked.
company 1992.(Pg. no. 395) 92

iii. Interference of cast in posterior region.
iv. Inaccurate articulator.
v. Inaccuracy by plaster.
company 1992.(Pg. no. 395) 93

4. Correcting the occlusal
disharmony
• Intraoral methods:

Checking the occlusal errors:
• Feather touch.
• Selective grinding intraorally - increases error.
• Accurate mounting in articulator – accurate.

a. Reduces patient participation.
b. Better vision.
c. Stable working foundation.
d. Absence of saliva – accurate marking.
e. Preventing occasional observation of patient.

(no displacement of mucosa) (Displacement of mucosa)

(i) Selective grinding of anatomic teeth:
To achieve balanced occlusion, uniform contact on;
1.Centric relation.
2.Eccentric
Working side- all posterior teeth and canine.
Balancing side- only posterior teeth.
3. Protrusive balance- incisal edge contact at the
same time posterior teeth contact.
102

Procedure:
104
Adjust horizontal and condylar
inclinations
Raise the incisal pin
Evaluate in centric and eccentric
position
Grinding
Refining the occlusal anatomy

Rules:
If cusp is higher in centric and eccentric – reduce.
If cusp is higher in centric only- deepen the
fossa/marginal ridge.
More contact in incisal and no contact in posterior:
labioincisal surface of mandibular teeth + palatal
surface of maxillary teeth.
105

Working side:
BULL
(non functional cusp)
Balancing side:

teeth together
Simultaneous bilateral posterior
contact
No anterior tooth contact
Distal of PM and 1st Molar and
mesial of 2nd molar
Mounting disc, Polishing

(iii) Occlusal equilibrium of Zero degree teeth:

Tissue conditioner
• Average displacement of soft tissue – 0.050 to

• Tissue conditioning is an effort to restore the
health of the tissues of the denture foundation
area before master impressions are made by
relining the dentures with temporary denture
reliners.

Conclusion
• The advanced age of average denture wearers,
and the nature of the denture bearing mucosa
appear to influence the nature of problems.
• Superimposed infections with candidal
organisms and traumatic lesions are the most
commonly encountered abnormalities.
• A thorough knowledge of factors involved in
construction of complete denture is essential
before attempting postinsertion check up.
