17
Q

A POOR MAXILLARY MAJOR CONNECTOR AND IS ONLY PRESCRIBED IF TORUS PALATINUS IS PRESENT AND PROHIBITS THE USE OF OTHER CONNECTOR

18
Q

IT IS THE ABILITY OF AN RPD TO RESIST DISLODGING FORCES DURING FUNCTION

A

Retention

19
Q

THIS RETENTION IS OBTAINED BY PLACING PORTIONS OF PARTIAL DENTURE INTO TOOTH OR SOFT TISSUE UNDERCUTS. USUALLY DERIVED FROM THE USE OF DIRECT RETAINERS

A

Mechanical retention

20

21
Q

A CLASS OF MECHANICAL RETENTION THAT ARE ARE MECHANICAL DEVICES SET INTO A CASTING OF A FULL CROWN. ALSO CALLED PRECISION ATTACHMENTS

A

Intracoronal Retainer

22
Q

A MECHANICAL RETENTION THAT ENGAGES AN EXTERNAL SURFACE OF AN ABUTMENT IN A NATURAL UNDERCUT OR PREPARED PREPARATION

A

Extracoronal retainer

23
Q

WHAT ARE THE TWO MAIN CLASSES OF CLASPS

A

Suprabulge retainer

Infrabulge retainer

24
Q

CLASP THAT APPROACH THE UNDERCUT FROM ABOVE THE HEIGHT OF CONTOUR

A

Suprabulge retainer

25
Q

CLASP THAT APPROACH THE UNDERCUT FROM BELOW THE HEIGHT OF CONTOUR

A

Infrabulge retainer

26
Q

THE MOST SIMPLE AND VERSATILE CLASP. CLASP OF CHOICE IN TOOTH BORNE CASES

A
