Fixed partial dentures transmit forces through the abutments to the periodontium. Failures are due to poor engineering, the use of improper materials, inadequate tooth preparation, and faulty fabrication. Of particular concern to prosthodontist is the selection of teeth for abutments. They must recognize the forces developed by the oral mechanism, and resistance.
Successful selection of abutments for fixed partial dentures requires sensitive diagnostic ability. Thorough knowledge of anatomy, ceramics, the chemistry and physics of dental materials, metallurgy, Periodontics, phonetics, physiology, radiology and the mechanics of oral function is fundamental.
The Indian Dental Academy is the Leader in continuing dental education , training dentists in all aspects of dentistry and offering a wide range of dental certified courses in different formats.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

A- Retention of Removable Partial Dentures
1. A- Retention of Removable Partial
Dentures

4.
5.
6. Is the resistance
of the partial
denture to vertical
displacement
away from the
tissues
Retention
7. 1. Have less surface area.
2. Are bathed in saliva.
3. Lower major connectors are
relieved.
The effect of physical forces is
less applicable to lower dentures
than upper because:
contrary to upper m. c. that are well adapted and their borders
are beaded against the underlying tissues.
4. Strong movements of the tongue
13. • Frictional fit
Indirect R.
Direct
retainers
Parts of the denture
engaging tooth and
tissue undercuts.
• Clasps
• Attachments
Mechanical means of
Retention
14. Components of a clasp
Clasp Retainers
A minor connector
A rest
A Reciprocal arm
A retentive clasp arm
19. Basic Principles of a Properly Designed Clasp
For a clasp to be
retentive its arm must
flex as it passes over
the height of contour
of tooth and engage
undercut in infrabulge
area of the teeth
2- Retention
21. 3- Support
1- Occlusal rest support prevents clasp from being
displaced in gingival direction. 2- lack of support
Basic Principles of a Properly Designed Clasp
22. 4- Reciprocation
Each retentive terminal should be opposed by a
reciprocal arm to resist any orthodontic pressure
exerted by the retentive arm during placement and
removal as it flexes about the height of contour
Basic Principles of a Properly Designed Clasp
23. 5- Bracing 6-Stabilization
All rigid parts of
clasps contribute
to this property
and resist
displacement of
clasp in horizontal
direction
Basic Principles of a Properly Designed Clasp
24. The clasp should not interfere with normal
gingival stimulation and its terminal should be
away from the gingival margin
7- The clasp should be designed on
biologic as well as mechanical bases.
X
3-4mm
25. 8- There should be a minimum of 5-mm space between
any two neighboring minor connectors
26. 9- Minor connector (or proximal plate)
must contact a definite guiding plane to
dictate path of insertion
27. What are the functions of guiding planes

28. 10- Undercut is better be found within the GINGIVAL1/3 for
better esthetics & mechanics
Post Is More Readily Removed by Application of Force Near Its Top
Than by Applying Same Force Nearer Ground Level
Bracing arm better located In the apical portion
of the Middle 1/3
29. The retentive clasp arm should
be passive and should not
exert any pressure against
the tooth until a dislodging
force is applied.
11- Passivity:
31. Factors Determining the
Retentive Force of a Clasp
1- Amount of undercut used
2- Angle of cervical convergence
3-Angle of approach
4- Flexibility of clasp arm
32. Amount of retention depends on
The greater the distance we go into the undercut the greater will
be the retention considering the same rigidity.
1-Depth of undercut
33. Undercut depth depends on cervical convergence of
the tooth rather than on distance below the survey line.
2- Angle of cervical convergence
34. 3-Angle of approach
According to the way of approaching the undercut
Gingivally approaching clasp Occlusally approaching clasp
35. 3-Angle of approach
Occ. approaching clasps are pulled up to
move occlusally. Ging. approaching
clasps are pushed up to move occlusally
(Trip action of the clasp)
36. 4- Flexibility of clasp arm
The more flexible the clasp
arm, the less will be the
retention (but don’t forget the trip
action of the clasp !!!!!)
More rigid clasps can be used
in tooth supported partial
dentures
37. a. The length of the clasp arm
b. The diameter of the retentive arm
c. Tapering
d. The cross sectional form
e. The material of alloy
f. The type of alloy
The degree of Flexibility of the clasp
arm depends on the following factors
38. Increasing arm length increases the
flexibility ,thus decreasing the retention
Factors affecting the Flexibility of clasp arm
a- The length of the clasp arm
39. The greater the length and tapering and
the less the diameter, the greater will
be the flexibility of the clasp arm
b. The diameter of the retentive arm
Flexibility of clasp arm:
40. Degree of taper , the retentive arm should be
uniformly tapered in such a way that the diameter at its
origin is twice that at its tip.
C- Tapering
Flexibility of clasp arm:
41. Round clasps are the
most flexible as they flex
in all direction thus
lowers the retention than
½ round and flat clasps
d- Cross sectional form
42. Flexibility of clasp arm:
f-The type of alloy
e- The material of alloy:
The wrought form is more resilient than
the same alloy of identical diameter in
cast form, because of its internal structure
Gold alloys are more flexible than
cobalt chrome alloys.
43. The wrought form is more
resilient than the same alloy of
identical diameter in cast form,
because of its internal structure
