CAN YOU IDENTIFY THE VARIOUS RPD COMPONENTS???

HERE ARE SOME REAL LIFE EXAMPLES


3/33

WHAT COMPONENTS CAN YOU SEE?


4/33

WHAT COMPONENTS CAN YOU SEE?

DENTURE BASE

RETENTION MAJOR CONNECTORA-P BAR

OCCLUSAL REST

DIRECT RETAINERINFRABULGE

CINGULUM RESTAS PART OF PLATING

RECIPROCATION VIALINGAUL PLATE

DENTURE TOOTH RETENTION VIA POST

ATING CAN ACT AS INDIRECT RETENTION


5/33


6/33

M.C. = PALATAL STRAP

CINGULUM RESTAS PART OF PLATINGAND ALSO ACTS AS INDIRECT RETENTI

NTURE BASETENTION

RECIPROCATION VIARECIPROCATING ARM

DOUBLEOCCLUSAL RE

RECIPROCATION VIARECIPROCATING ARM

DIRECT RETAINER

CIRCUMFERENTIAL WROUGHT WIRE

DENTURE BASE RETENTION

NOTE SPACE BETWEEN IT AND TISSUE


9/33


10/33

-DIRECT RETAINERS/CAST CIRCUMFERENTIAL

-CAN ALSO BE CONSIDERED EMBRASURE CLASP TYPE SINCE-THEY COME THROUGH AN EMBRASURE BETWEEN TWO TETH.-YOU WOULD EXPECT TO SEE RECIPROCATION OF SOME SORT -ON THE LINGUALS OF THESE TEETH.


11/33


12/33

M.C. = LINGUAL PLATE

-DIRECT RETAINER/SUPRA BULGE

-WROUGHT WIRE WHICH IS LASER WELDED TO THE DENTURE BASE RETENTION

GUIDE PLATEOVERLYING A GUIDE PLANE ON TOOTH.

PLATING AS INDIRECT RETENTION


13/33


14/33

M.C. = LINGUAL PLATE

DIRECT RETAINER/CAST CIRCUMFERENTIAL/SUPRABULGE-usually found on lingual of lower molarsand buccal of upper molars due to inclination of teeth

RECIPROCATING ARM

D.B.R.

INCISALREST


15/33


16/33

RECIPROCATING ARM

OCCLUSAL REST

STILL PART OF M.C.

DIRECT RETAINER/CAST/INFRABULDGE T

INCISAL REST

GUIDE PLATEOVERLYING A GUIDE PLANE ON TOOTH


17/33


18/33

INCISAL REST

DIRECT RETAINER/CAST CIRCUMFERENTIAL/SUPRABULDGE

RECIPROCATING ARM


19/33


20/33


CINGULUM REST

OCCLUSAL REST

DIRECT RETAINER

DIRECT RETAINER

RECIPROCATING ARM



21/33


22/33


DOUBLE OCCLUSAL REST

DIRECT RETAINECAST CIRCUMFE

-TRUE EMBRASU

DENTURE BASE RETENTION

RECIPROCATION IS LINGUAL PLATING


23/33


24/33

M.C. = LINGUAL BAR

THIS IS PART OF M.C. ALSO

OCCLUSAL REST

TRUE MINOR CONNECTOR-OFTEN BLEND IN WITH OTHER COMPONENTS

DENTURE BASE-MECHANICAL RETENTION TO D.B.R. ANDCHEMICAL BOND TO DENTURE TEETH


25/33


26/33

PART OF M.C.

GUIDE PLATE

DIRECT RETAINER/CAST/INFRABULGEI-BAR

DIRECT RETAINER/CAST CIRCUMFERENTIAL/SUPRABUL

TRUE MINOR CONNECTOR-OFTEN BLEND IN WITH OTHER COMPONENTS


27/33


28/33

M.C. = A.P. BAR

D.B.R.

D.R. = I-BAR

D.R. = CAST CIRCUMFERE

RECIPROCATION = LINGUAAL PLATING

CINGULUM REST ALSO ACTS AS INDIRECT RETENTIO


29/33


30/33

D.R. = I-BAR

GUIDE PLATE

D.B.R-NOTE SPACE BETWEEN IT AND RIDGE FOR PROCESSED ACRYLIC TO FILLAND MECHANICALLY ATTACH TO FRAMEWORK


31/33


32/33

M.C. = U-SHAPED (HORSESHOE)

D.B.R. = METAL WITH BEADS

GUIDE PLATE

D.R. = CIRCUM-NOTE WHERE

CINGULUM AND OCCLUSAL RESTS BOTH ACT AS I.R.


33/33

ANOTHER HORSESHOE BUT A CLASS I
