This document provides an introduction to fixed prosthodontics, including terminology, classifications of crowns and bridges, and types of prosthetics. It defines fixed prosthodontics as the replacement of missing teeth by artificial substitutes that are not removable. Crowns are described as restorations that replace the coronal portion of a tooth, and can be full or partial coverage. Bridges are fixed prostheses used to replace one or more missing teeth, consisting of retainers, pontics, and sometimes connectors. Bridges are classified based on retention, materials used, and location in the mouth.

Terminology & classification

4. *Terminology
*prothesis
Artificial replacement of any body part.
Dental prothesis
Removalble
prothesis
Fixed
prothesis

5. It is the field concerned with the restoration
or the replacement of missing teeth and
surrounding structure by artificial substitute
that are removable.
Removable prosthodontics

6. Fixed prosthodontics:
it is a branch of dentistry concerned with the
restoration or the replacement of the tooth or teeth
by artificial substitute that are not removable from
the tooth

7. Advantages of replacing missing teeth
-Function
-Esthetics
-Occlusal stability
Other Advantages
-Speech
-Periodontal splinting
-Orthodontic retention
-Restoring occlusal vertical dimension

9. Prothetic options for missing tooth
1- implant
2- fixed partial denture(bridge)
3- removable

10. Fixed prosthodontics:
Crown bridge
Crown : is an artificial
restoration of the coronal
portion of the natural
tooth.

11. Crown
1- clinical crown
2- anatomical crown
3- radiographic crown
4- artificial crown

13. A)Full coverage crown:
It is an extra coronal restoration
that covers all the surfaces of
the prepared clinical crown
Types of crowns:

14. *full veneer metal
crown: it is a full
metal cast crown
that covers all the
coronal tooth
surface.

15. *Jacket crown: it is a
non metallic, full
coverage restoration
(porcelain) that rebuilds
the prepared clinical
crown of the anterior
teeth and restores it
esthetically and
functionally.

16. * Veneered crown: it is
a full cast crown having
porcelain or acrylic facing
on the labial or buccal
surface.

18. * full veneered crown: it
is a full cast crown having
all surfaces covered with
porcelain.

20. Post crown: it is an artificial
restoration of the coronal
portion of the natural tooth
maintained in position mainly
by post inserted in the
prepared root canal.

23. •Temporary crown: it is a
crown made and used
temporally in the protection of
the prepared tooth until the
final restoration is completed
and cemented

24. B-partial coverage
crown
Partial-coverage crown is an
extracoronal restoration that
covers only part of the
clinical crown.

25. * Three-quarter
crown: it is a partial
veneer crown in
which the buccal
surface is left
uncovered.

26. * Reverse Three-quarter crown:
it is a modified type of Three-
quarter crown where the lingual
surface is unprepared instead of
buccal surface.

27. * One half crown: it is a
modified type of Three-quarter
crown involving one proximal
surface and nearly those half of
buccal and lingual surfaces
adjacent to it and most of /or all
the occlusal surface.

29. • Seven eight crown : it is a
partial coverage crown
covering all the surfaces of the
crown except the mesio –
buccal cast .

31. • * Mac Boyle retainer : it is a
modified type of Three-quarter
crown with retention derived
from grooves at the labial line
angles instead of the proximal
surfaces.

32. • * Pinledge retainer : it is a
modified form of partial
veneer crown using
dowel Pins in the coronal
portion of the tooth as
means of retention .

34. Other Types of Prosthetics fixed
to a single tooth :
• Laminates : are thin facings of
ceramic fixed directly to teeth
using resin cement.

36. * Inlay retainer : is a metallic or
ceramic retainer that restores the
proximal and occlusal surfaces but
does not protect or cover the cusps
entirely.

37. *Onlay retainer : It is a modified
MOD inlay with cusp overlays on the
occlusal surface protecting the integrity
of the remaining tooth structure .

40. Bridge: (fixed prosthesis)
(fixed partial denture): is a non
movable prosthesis which is
rigidly attached to one or more
abutment teeth to replace one or
more lost missing teeth.

42. Component Parts of bridge
Abutment tooth Retainer
Pontic
Connector

43. * Abutment tooth: is the
natural tooth which supports
and retain the bridge at one
or both teeth.

44. * Pier abutment: is an isolated
abutment tooth, where the anterior and
posterior adjacent teeth to it are missing.

45. * Pontic: is that part of the
bridge which act the actual
substitute for the lost tooth and
is suspended between the
retainers replacing the lost
natural tooth functionally and
esthetically.

46. * Retainer: The artificial
restoration rebuilding
prepared abutment tooth
and by which the pontic is
attached to the abutment.

47. * Connector: is that part of the
bridge uniting the pontic (s) with the
retainer(s), so that to join the component
parts of the bridge.
1-Rigid connector: soldered type
joint
2-Non Rigid connector: a Brocken-
stress or dove tialed occlusal or
subocclusal rest allowing for some
individual movement of the abutment
teeth.

48. * Fixed fixed bridge: is a
bridge where the retainer and
pontic s are all solder together
and the bridge is cemented at
both ends to the abutment teeth.
Types of bridges

50. * Fixed supported bridge :
is a bridge which is not actually joined
to one of the terminal abutment teeth
but is connected to it by means of a non
– rigid connector allowing some
individual movement of the abutment
teeth.

53. * Cantilever bridge ( fixed
free bridge ) : is a bridge
where the pontic is fixed to and
drives its support from one or
double retainers at one end only
while the other end
unsupported.

55. * Spring Cantilever bridge
: is Cantilever bridge where the
pontic is at the end of slightly
curved resilient arm driving its
support from an abutment
remote from the edentulous
space.

57. * Removable bridge , precision
attachment bridge : is a bridge
where each retainer consists of 2
parts , one fixed to the abutment
tooth and one soldered to the pontic
and the bridge can removed by the
patient for cleaning purpose.

59. * Temporary bridge: is a
bridge made and used for the
protection of the prepared teeth,
tissue control and maintenance of
the space till completion and
cementation of the bridge.

61. * Resin bonded retainer: is a
restoration consisting of one or two
pontics supported by thin metal or
ceramic retainers placed lingually and
proximally on the abutment teeth.
These prosthesis rely in part on
adhesive bonding between etched
enamel and the metal or ceramic
retainers.

63. * Implant supported fixed
prosthesis: are surgically placed
implant within bone and projected
though the mucosa, on which the
abutment are screw retained , fixed
partial denture the constructed on
the abutment

65. * Simple bridge: is a one single
type bridge which may be fixed ,fixed
free, cantilever or spring cantilever.

66. * Compound bridge: is a
combination type bridge composed
of two or more of the simple types

67. All ceramic bridge: is a bridge
made entirely of ceramics.

68. * Complex bridge: is a bridge that extends at
one of its terminal beyond the canine.
* Unilateral bridge: is a bridge consisting of 2 or
3 anterior teeth that doesn't cross the midline.
* Bilateral bridge: is a bridge consisting of 3 or 4
teeth which involves teeth on both sides of the
midline.
