Overview Flashcards
What are the characteristics of the partial edentulous patient population
increasing
patients are keeping teeth longer
71.5% of 65-74 year old patients are partially edentulous
By the year 2030, 26% of the US population is expected to be >65 years old, what is the trend of their life style
focusing on maintaining an active and productive life; oral health is expected to be more highly sought after, especially partially edentulous care
What is the Kennedy Class of a bilateral edentulous area located posterior to the remaining natural teeth
class I
What is the Kennedy class of an unilateral edentulous area located posterior to the remaining natural teeth
class II
What is the Kennedy class of an unilateral edentulous area with natural teeth remaining both anterior and posterior to it
class III
What is the Kennedy class of a single, but bilateral edentulous area located anterior to the remaining natural teeth
class IV
What is the first Applegate Rule
classification should follow, rather than precede any extractions of teeth that might alter the original classification
What is the second Applegate rule
if a third molar is missing and not to be replaces, it is not considered in the classification
What is the third Applegate rule
if a third molar is present and is to be used as an abutment, it is considered in the classification
What is the fourth Applegate rule
If a second molar is missing and is not to be replaced, it is not considered in the classification
What is the fifth Applegate rule
the most posterior edentulous area always determines the classification
What is the sixth Applegate rule
edentulous areas other than those determining the classification are referred to as modifications and are designated by their number
What is the seventh Applegate rule
The extent of the modification is not considered, only the number of additional edentulous areas
What is the eighth Applegate rule
There can be no modification areas in class IV arches
This connects the parts of an RPD located on one side of the arch with those on the opposite side
major connector
What are the maxillary major connectors
anterior-posterior palatal strap single palatal strap modified full palatal complete palatal coverage U-shaped or horseshoe
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
full palatal coverage
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
modified full palatal coverage
This is the least rigid maxillary connector and may be needed to avoid torus palitinus, unusual vault shape
U-shpaed or horseshoe shaped
What are the mandibular major connectors
lingual bar
lingual plate
labial bar; swinglock
This mandibular connector has the highest patient acceptance
lingual bar
What is the functional depth the lingual vestibule needed for the lingual bar
7-8mm
What are the measurements of the lingual bar
4mm in height
3-4mm from free gingival margin
When is the lingual plate indicated (3)
when the lingual vestibule is <7mm
may be used when additional loss of teeth is anticipated
may be used when lingual tori are present
