Minor connectors

Question 1

Minor connectors function

Answer 1

1-connect all components (rests, clasps, denture base) to major connector
2-distribute load to all components, over ridge and abutment

Question 2

Minor connectors types

Answer 2

1-join clasp to major connector

2-join indirect retainer /axillary rest to major connector

3-join denture base to major connector

4-approach arm of gingivally approach clasp

Question 3

In (join clasp to major connector)

if clasp on abutment near to saddle so minor connector is….
And should be …

Answer 3

proximal plate

Should be: *rigid
*locate on guiding plane (bounded saddle contact 2/3 proximal surface in length, in free end saddle
contact 3mm in length)

Question 4

In (join clasp to major connector)

if clasp on abutment away from saddle Use…..
And should be

Answer 4

general minor connector ( lingual plate )

Should be
*cross section is half round *relief when cross free gingival margin to avoid trauma
*locate in embrasure ‘‘interdental ‘‘between teeth, never positioned on convex lingual surface of tooth

Question 5

join denture base to major connector
They are finish line:
Finish line → represent line of demarcation of acrylic or junction between 2 different materials,
(butt joint)
There are 2 finish :

Answer 5

1-internal finish line → obtained by relief on master cast modification.
2-external finish line → obtained by carving of wax pattern on refractory cast.
*in free end saddle → use combined base. so have internal and external finish line (where fitting,
polished surface is acrylic)

*in bounded saddle → use solid base where fitting surface is metallic and polished is acrylic. So
there is only external finish line.
→ saddle is lead wire or beaded or nail head.

Question 6

(approach arm of gingivally approach clasp)

Answer 6

only minor connector which is flexible due to increase length

Question 7

all types of minor connector are rigid except

Answer 7

approach arm of gingivally approach clasp is flexible
