Lecture 2 - Removable Prosthodontics

Question 1

What is a Removable Partial Denture

Answer 1

A dental prosthesis that replaces some teeth in a partially edentulous arch; the removable partial denture can be readily inserted and removed from the mouth by the patient

Question 2

How should a partial denture be described

Answer 2

a fixed partial denture, or a removable partial denture based on the patient’s capability to remove or not remove the prosthesis

Question 3

Kennedy Class I

Answer 3

Bilaterally located edentulous spaces posterior to natural teeth

Question 4

Kennedy Class II

Answer 4

Unilateral edentulous space that is posterior to natural teeth

Question 5

Kennedy Class III

Answer 5

A unilateral edentulous space with natural teeth anterior and posterior to it

Question 6

Kennedy Class IV

Answer 6

A single edentulous space located anterior to the remaining teeth ( but bilateral crossing the midline)

Question 7

What is Applegate’s modification to Kennedy’s Classification

Answer 7

should follow required extractions

considers 3rd molars

Question 8

What should determine the classification (Kennedy w/ Applegate modification)

Answer 8

the posterior area

Question 9

Endentulous areas other than classifications should be known as

Answer 9

modifications and are designated a letter(A or P) and number(how many spaces)

Question 10

can modifications be included in a class IV arch

Answer 10

no

Question 11

Kennedy Class V

Answer 11

An edentulous area bound by teeth anteriorly and posteriorly but where the anterior tooth is NOT suitable to be used as an abutment

Question 12

Kennedy Class VI

Answer 12

An edentulous situation where the bounded teeth are capable of supporting the prosthesis

Question 13

Major and minor connectors

Answer 13

Connect the parts of the prosthesis from one side to the other. It is the unit of the removable partial denture to which all other parts are directly or indirectly attached

location, shape, and thickness are important to remember

Question 14

Where should a major connector be located

Answer 14

free of movable tissue

should not impinge the gingival tissue

avoid bony prominence

relief is provided on areas of interference (such as tori)

relief provided to prevent impingement or irritation during function

Question 15

what are the main parts of a mandibular major connector

Answer 15

lingual bar
lingual plate
labial bar

Question 16

what are the other parts of a mandibular major connector

Answer 16

sublingual bar
lingual with cingulum bar
cingulum bar

Question 17

Lingual Bar

Answer 17

cross section half pear shaped with thickest part at inferior border. 4 mm in height . At least 3mm from the free gingival margin

Question 18

Lingual Plate

Answer 18

used when the free gingival margin to the floor of the mouth is less than 7 mm. OR when anterior teeth are mobile with questionable longevity. Superior border placed on the junction of the incisal and middle thirds of the tooth

Question 19

labial bar

Answer 19

Same as the Lingual Bar but placed buccally (facially) due to severe inclination of the remaining teeth
