Components of CPD

2. Maxillary and mandibular Kennedy’s Class II modification 1
partially edentulous arch

5. Cast
• Prepared by casting procedure.
• Wax pattern fabricated is replaced
by metal (e.g. Co-Cr) by casting.
Partial
• Used for partially edentulous
arches
Denture
• Replaces one or more missing
teeth to enhance function and
esthetics

Made only of acrylic Only for temporary use

14. Direct Retainer:
"A clasp or attachment placed on an
abutment tooth for the purpose of holding
a removable denture in position."

15. Indirect Retainer:
“A part of a removable partial denture which
assists the direct retainers in preventing
displacement of distal extension denture bases
by functioning through lever action on the
opposite side of the fulcrum line"

16. Rest (as a part of direct retainer assembly):
" A rigid extension of a fixed or removable partial
denture which contacts a remaining tooth or teeth
to dissipate vertical or horizontal forces."

17. Major Connector:
“A part of a removable partial denture
which connects the components on one side
of the arch to the components on the
opposite side of the arch"

18. Minor Connector:
"The connecting link between the major connector
or base of a removable partial denture and other
units of the prosthesis, such as clasps, indirect
retainers and occlusal rests."

19. Denture teeth on acrylic denture base:
• Denture base is the part of the denture that
forms the tissue surface of the denture over the
edentulous area. It is usually made of acrylic
resin.
• It helps to distribute the forces acting on the
denture over the entire residual ridge.
• The denture base also functions to hold the
tooth replacements in position.
