definitiondefinition
Prosthodontics is the dental specialty pertaining to the diagnosis,
treatment planning, rehabilitation and maintenance of the
oral function, comfort, appearance and health of patients with clinical
conditions associated with missing or deficient teeth and/or
maxillofacial tissues using biocompatible substitutes

Definition

“A partial denture that is luted or otherwise
securely retained to natural teeth, tooth roots
and/or dental implant abutments that furnish

11. INDICATIONS OF FIXED PROSTHESIS.
One or two adjacent teeth are missing in the same arch or
short span edentulous arches.
The supportive tissues are healthy.
Suitable abutment teeth are present.
The patient is in good health and wants to have the prosthesis
placed.
The patient has the skills and motivation to maintain good
oral hygiene.
Patient’s preference

12. Contraindications for a Fixed Prosthesis
oNecessary supportive tissues are diseased or missing.
oSuitable abutment teeth are not present.
oThe patient is in poor health.
oThe patient is not motivated to have the prosthesis
placed.
oThe patient has poor oral hygiene habits.
oThe patient cannot afford the treatment.

CROWCROW
NN
It is a cemented extracoronal restoration that covers or veneers the
outer surface of the clinical crown.
Primary function is to protect the underlying tooth structure &
restore the function, form and esthetics.
TYPES

15.  ( )
FullVeneerCrown castmetal
 ,
If it covers allof the crown the restoration is a full or

complete veneer crown

It may be fabricated entirely of a goldalloy or some other
, .
untarnishable metal a ceramic veneer fused to metal

16. INDICATIONS
• Teeth that have extensive coronal destructions by caries or trauma
•Restoration of choice whenever maximum retention is needed
•Indicated on endodontically treated teeth
•Correction of occlusal plane
CONTRAINDICATIONS
•If less than maximum retention and resistance is needed
•Wherever intact buccal or lingual wall exists
•Enameloplasty
•For high esthetic needed exists like anterior teeth

17. Advantages
•Strong
•High retentive qualities
•Can be modify form and occlusion
•Easy to obtain adequate resistance form
Disadvantages
•Removal of large amount of tooth structure
•Display of metal

18. METAL CERAMIC CROWNS
The restorations consists of a complete coverage cast metal crown that is
veneered with a fused porcelain to mimic the appearance of a natural tooth
Indications
•Esthetics
•Gingival involvement
•If porcelian jacket crowns is contraindicated
Contraindications
•Large pulp chamber
•Intact buccal wall

19. Advantages
•Superior esthetics
•Retentive qualities are excellent
Disadvantages
•Removal of substantial tooth structure
•Fracture can occur
•Difficult to obtain accurate occlusion in glazed porcelain
•expensive

20. Partial Veneer Crown
An extracoronal metal restorations that covers only part of the clinical
crown is considered to be a partial veneer crown
Partial Veneer
Crown
MOD Gold Onlay

21. Indications
•Clinical crown of average length or longer
•Intact buccal/labial surface
•Well supported by sound tooth structure
Contraindications
•Short teeth
•High caries index
•Extensive destruction
•Not used in endodontically treated teeth
•Poor alignment
•Bulbous teeth
•Thin teeth

22. Disadvantages
•Less retentive than full crown
•Limited adjustment of path of withdrawal
•Not indicated on vital teeth
Advantages
•Conservative of tooth structure
•Easy access to margins
•Less gingival involvement
•Verification of seating simple

23. Three-quarter crowns
This type of crowns restore the occlusal surfaces and the
three of the four axial surfaces but not including the
facial surfaces

24. Pinledge
Indications
•High esthetic requirement
•Undamaged anterior teeth
•When proximal grooves are impossible to prepare
•To alter lingual contour of maxillary anterior teeth
A partial veneer retainer preparation incorporating
pins holes to provide retention

25. Contraindications
•Large pulp
•Non vital teeth
•Thin teeth
• carious involvement
Advantages
•Minimal tooth reduction
•Minimal marginal length
•Minimal gingival involvement
•Adequate retention
•Excellent esthetics
Disadvantages
•Less retentive
•Techanically demanding

26. INLAY
A fixed intracoronal restoration; a dental
restoration made outside of a tooth to correspond to the form of
the prepared cavity, which is then luted into the tooth
Inlay may be used as a single tooth restorations for proximo-occlusal or
gingival lesions with minimal to moderate extensions.
They may be made up of gold alloy or ceramic material.
Inlays are similar to fillings but the entire work lies within the cusps on the
chewing surface of the tooth.

27. Indications
•Small carious lesion
•Adequate dentinal support
•Low caries rate
•Patient request for gold restorations
Contraindications
• high caries index
•Poor plaque control
•MODs
•Poor dentinal support require
wide preparation

28. ONLAY
A restoration that restores one or more cusps and
adjoining occlusal surfaces or the entire occlusal surface and is retained
by mechanical or adhesive mean
It is used for restoring more extensively damaged posterior teeth needing wide mesio-
occluso-distal restorations.

29. Indications
•Worn or carious teeth with intact buccal and lingual
cusps
•MOD amalgam requiring replacements
•Low caries rate
Contraindications
•High caries risk
• poor plaque control
•Short clinical crown/extruded tooth
•bruxism

30. Laminate Veneers/Facial Veneers

It consists of a thin layer of dentalporcelain

or cast ceramic that is bonded to the facial

surfaces of the tooth with an appropriate
resin

It is used in situations requiring an

improved cosmetic appearance on the
.
anterior tooth

31. PARTS OF FIXED PARTIAL DENTURE
RETAINER
ABUTMENT
PONTIC
CONNECTOR

32. RETAINER
Any type of device used for the stabilization
or retention of a prosthesis
Positioned at margin - less susceptible to caries or
recurrence of caries
Rigidity – withstand the requisite load
Functional adaptation and protect the tooth against
its fracture
Least destroys the cervical marginal ridge

33. Types of retainer
• Full veneer crowns
• Partial veneer crowns
• Conservative retainers
• All metal retainers
• Metal ceramic retainers
• All ceramic retainers
• All acrylic retainers

34. Pontics
An artificial tooth on a fixed dental prosthesis that
replaces a missing natural tooth, restores its function, and usually
fills the space previously occupied by the clinical crown
Pontics

35. Requirements of pontics
-restore function
-provide esthetics and comfort
-be biologically acceptable
-permit effective oral hygeine
-preserve underlying residual mucosa
Material used
•Metal-ceramic pontics
•Resin veneered
•All metal
•Facings

36. ABUTMENT
A tooth, a portion of a tooth, or that portion of a dental implant that serves to
support and/or retain a prosthesis

37. Connectors
Fixed dental prosthodontics, the portion of a fixed dental
prosthesis that unites the retainer(s) and pontics
Types-
-Rigid connectors
-Non rigid connectors
-tenon mortise connectors
-loop connectors
-split pontic connectors
-cross pin and wing connectors

38. Nonrigid connectors

39. Loop connectors
Loop connectors are used for when existing diastema is to be
maintained in the planned fixed prosthesis
T he connector consists of a loop on the lingual aspect of the prosthesis that
connects adjacent retainers and /or pontics
