Overview

Question 1

What are the characteristics of the partial edentulous patient population

Answer 1

increasing
patients are keeping teeth longer
71.5% of 65-74 year old patients are partially edentulous

Question 2

By the year 2030, 26% of the US population is expected to be >65 years old, what is the trend of their life style

Answer 2

focusing on maintaining an active and productive life; oral health is expected to be more highly sought after, especially partially edentulous care

Question 3

What is the Kennedy Class of a bilateral edentulous area located posterior to the remaining natural teeth

Answer 3

class I

Question 4

What is the Kennedy class of an unilateral edentulous area located posterior to the remaining natural teeth

Answer 4

class II

Question 5

What is the Kennedy class of an unilateral edentulous area with natural teeth remaining both anterior and posterior to it

Answer 5

class III

Question 6

What is the Kennedy class of a single, but bilateral edentulous area located anterior to the remaining natural teeth

Answer 6

class IV

Question 7

What is the first Applegate Rule

Answer 7

classification should follow, rather than precede any extractions of teeth that might alter the original classification

Question 8

What is the second Applegate rule

Answer 8

if a third molar is missing and not to be replaces, it is not considered in the classification

Question 9

What is the third Applegate rule

Answer 9

if a third molar is present and is to be used as an abutment, it is considered in the classification

Question 10

What is the fourth Applegate rule

Answer 10

If a second molar is missing and is not to be replaced, it is not considered in the classification

Question 11

What is the fifth Applegate rule

Answer 11

the most posterior edentulous area always determines the classification

Question 12

What is the sixth Applegate rule

Answer 12

edentulous areas other than those determining the classification are referred to as modifications and are designated by their number

Question 13

What is the seventh Applegate rule

Answer 13

The extent of the modification is not considered, only the number of additional edentulous areas

Question 14

What is the eighth Applegate rule

Answer 14

There can be no modification areas in class IV arches

Question 15

This connects the parts of an RPD located on one side of the arch with those on the opposite side

Answer 15

major connector

Question 16

What are the maxillary major connectors

Answer 16

anterior-posterior palatal strap
single palatal strap
modified full palatal
complete palatal coverage
U-shaped or horseshoe

Question 17

This is indicated when there is ≤ 6 teeth, shallow vault; very small mouth or flat or flabby ridges, when all posterior teeth are to be replaced bilaterally

Answer 17

full palatal coverage

Question 18

This is a wide palatal strap; indicated for distal extension when support of palate needed; but there is desire to not cover the rugae area

Answer 18

modified full palatal coverage

Question 19

This is the least rigid maxillary connector and may be needed to avoid torus palitinus, unusual vault shape

Answer 19

U-shpaed or horseshoe shaped

Question 20

What are the mandibular major connectors

Answer 20

lingual bar
lingual plate
labial bar; swinglock

Question 21

This mandibular connector has the highest patient acceptance

Answer 21

lingual bar

Question 22

What is the functional depth the lingual vestibule needed for the lingual bar

Answer 22

7-8mm

Question 23

What are the measurements of the lingual bar

Answer 23

4mm in height

3-4mm from free gingival margin

Question 24

When is the lingual plate indicated (3)

Answer 24

when the lingual vestibule is <7mm
may be used when additional loss of teeth is anticipated
may be used when lingual tori are present

Question 25

This is sometimes used with a lingual plate

Answer 25

swinglock; hinged continuous labial bar

Question 26

When is the swing lock indicated (3)

Answer 26

missing key abutments
unfavorable tooth contours
labial inclination of teeth

Question 27

This is the most rigid maxillary major connector, may be used to circumvent tori, or for a Kennedy class IV

Answer 27

anterior-posterior palatal strap

Question 28

What are the dimensions of the anterior-posteiror palatal strap

Answer 28

anterior strap should be no further anterior than the most anterior rests, following the valleys of the rugae and runs perpendicular to the mid palatine suture
posterior strap should be as far posterior as possible but remain anterior to the soft palatal or vibrating line

Question 29

This maxillary major connector is indicated primarily for Kennedy III of which the width is a wide as the edentulous space, the anterior border should be posterior to rugae area

Answer 29

single palatal strap

Question 30

This maxillary major connector provides the most rigidity and support but also has the most soft tissue coverage, may alter taste and tactile sensation, phonetic problems

Answer 30

complete palatal coverage

Question 31

This mandibular major connector may be used when depth on the vestibule exceeded 7-8mm; simplest, high patient acceptance, half pear shaped, 4mm in height

Answer 31

lingual bar

Question 32

This mandibular major connector is indicated when the vestibule is less than 7mm, may be used when additional loss of teeth is anticipated, may be used when lingual tori are present, indicated when all posterior teeth are to be replaces bilaterally because it offers indirect retention

Answer 32

lingual plate
