Applegate’s rules - classification ———- removal of hopeless teeth
follows
Applegate’s rules - 3rd molars are
disregarded if missing/not to be replaced
Applegate’s rules - if 2nd molar is missing and not to be replaced,
disregard it.
Applegate’s rules - most ———— edentulous are determines classification
posterior
Applegate’s rules - other edentulous areas other than the class are called
mods.
Applegate’s rules - extent of mod is not
considered.
Applegate’s rules - no mod areas in
class IV
Major connector
connects parts of RPD located on one side of the arch with those on the opposite side.
Lingual bar
major mand connector - 4mm tall bar, 3mm from FGM to FOM with raised tongue.
For lingual bar, you need
7mm w/patient lifting tongue.
More missing teeth requires
more palate coverage.
—– is the workhorse of kennedy 3 mod 1
palatal strap
Anterior posterior palatal strap is the most
rigid for the amount of palate covered.
Full palatal coverage indicated when under or equal to
6 teeth
Modified full palatal coverage -
wide palatal strap indicated for distal extension when support of palate needed, but no desire to cover rugae area
U shaped or horseshoe shaped -
least rigid, flexes, may be needed to avoid torus palitinus
Lingual bar is the highest in
patient acceptance.
When anticipating loss of natural teeth, use
lingual plate - easier to add to
Lingual plate for when lingual vestibule is
under 7mm. Used when lingual tor are present.
Swinglock, hinged continuous labial bar indicated when
missing key abutments, unfavorable tooth contours, labially inclined teeth.
