1
Q

What are the characteristics of the partial edentulous patient population

A

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

2
Q

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

A

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

3
Q

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

A

class I

4
Q

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

A

class II

5
Q

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

A

class III

6
Q

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

A

class IV

7
Q

What is the first Applegate Rule

A

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

8
Q

What is the second Applegate rule

A

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

9
Q

What is the third Applegate rule

A

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

10
Q

What is the fourth Applegate rule

A

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

11
Q

What is the fifth Applegate rule

A

the most posterior edentulous area always determines the classification

12
Q

What is the sixth Applegate rule

A

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

13
Q

What is the seventh Applegate rule

A

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

14
Q

What is the eighth Applegate rule

A

There can be no modification areas in class IV arches

15
Q

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

A

major connector

16
Q

What are the maxillary major connectors

A
anterior-posterior palatal strap
single palatal strap
modified full palatal
complete palatal coverage
U-shaped or horseshoe
17
Q

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

A

full palatal coverage

18
Q

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

A

modified full palatal coverage

19
Q

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

A

U-shpaed or horseshoe shaped

20
Q

What are the mandibular major connectors

A

lingual bar
lingual plate
labial bar; swinglock

21
Q

This mandibular connector has the highest patient acceptance

A

lingual bar

22
Q

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

A

7-8mm

23
Q

What are the measurements of the lingual bar

A

4mm in height

3-4mm from free gingival margin

24
Q

When is the lingual plate indicated (3)

A

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

25
Q

This is sometimes used with a lingual plate

A

swinglock; hinged continuous labial bar

26
Q

When is the swing lock indicated (3)

A

missing key abutments
unfavorable tooth contours
labial inclination of teeth

27
Q

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

A

anterior-posterior palatal strap

28
Q

What are the dimensions of the anterior-posteiror palatal strap

A

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

29
Q

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

A

single palatal strap

30
Q

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

A

complete palatal coverage

31
Q

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

A

lingual bar

32
Q

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

A

lingual plate
