Edentulous Flashcards
dental prosthesis
artificial replacement of one or more teeth and/or associated structures
removable partial denture
dental prosthesis that is patient removable and supported by teeth and soft tissue or teeth alone
edentulous
having no teeth, toothless, complete loss of natural teeth: lower self image decreased quality of life reduced daily function
RPD treatment obj
restore full arch form and fxn provide a prosthesis that is comfortable, esthetically pleasing, functional and does not interfere with the patient’s speech
partially edentulous
dental arch in which one or more but not all of the natural teeth are missing. lower self image decreased quality of life reduce daily fxn
study casts
absolute necessity in considering any prothesis: accurate reproduction of the teeth and adjacent tissue
ideal treatment plan
the best, most preferred type of treatment for each of the patient’s problems. may not take into account patient modifiers or the patient’s treatment objectives
modified treatment plan
balanced w/ patient’s treatment objectives w/ those treatment objectives of the clinician need to explain the pros of the ideal and the cons of the less than ideal plan - this is necessary in order to obtain true informed consent from the patient overall need to convey: practical for this patient
abutment teeth
any tooth or dental implant that supports and/or retains a dental prosthesis
abutment teeth - “double duty”
function and maintain arch integrity support the removable partial denture
kennedy classification
allowed visualization of the type of partially edentulous arch being considered permitted differentiation between tooth-supported and tooth-tissue supported partial dentures serve as a guide to the type of design to be used universally accepted
kennedy classification I
bilateral edentulous areas located posterior to natural teeth
kennedy classification II
a unilateral edentulous area located posterior to remaining natural teeth
kennedy classification III
a unilateral edentulous area w/ natural teeth remaining both anterior and posterior to it
kennedy classification IV
a single, but bilateral (crossing the midline), edentulous area located anterior to the remaining natural teeth (tooth borne)
Rule 1 for applying kennedy’s classification
classification should follow not precede any extractions of teeth that might alter the original classification
Rule 2 for applying kennedy’s classification
if a third molar is missing and not to be replaced, it is not considered in the classification
Rule 3 for applying kennedy’s classification
if a third molar is present and is to be used as an abutment, it is considered in the classification
Rule 4 for applying Kennedy’s classification
if a second molar is missing, and is not to be replaced, it is not considered in the classification
Rule 5
the most posterior edentulous area (or areas) always determines the classification
Rule 6
edentulous areas other than those determining the classification are referred to as modifications and are designated by their number
Rule 7
the extent of the modification is not considered only the number of additional edentulous areas
Rule 8
there can be no modification areas in Class IV arches
Class II, Modifications 1
Record base purpose
correctly orient diagnostic casts and final casts for removable, fixed and complete denture cases
should be stable
rigid material
maximum contact with supporting tissues
accurately fit the casts and the patient’s mouth
smooth, rounded borders
Record Base Rationale
necessary to relate, articulate and mount casts on an articulator
Triad: Visible Light Cured resin: VLC
Air Barrier Coating: ABC
polymerization (curing) of the resin tray matieral is inhibited by O2
this O2 inhibited uncured layer is prevented from forming by ABC
Triad Curing Unit
Hanau Torch
instrument used to melt and control the shape and flow of wax and modeling compound in numerous lab and clinical procedures
function as an alcohol torch and torch with a needle point flame
15 scalpel blade
Instruments needed
WS2 waxing instrument
CVHL 357 (Hollenback)
Baseplate Wax
extra hard baseplate wax to be adapted to record base to use in mounting cast with facebow transfer and bite registration
