Diagnostic Waxing and Provisional Restorations Flashcards
Diagnostic Waxing
Elements used as part of a Diagnostic Wax up:
(5)
-A full health history
-Intra-oral examination of patient
-Diagnostic Casts (mounted)
-Occlusal Evaluation
-Esthetic evaluation – Primarily for anterior
FPD work. However, should also be
considered for posterior work as well.

Diagnostic Waxing – Systemic Approach
8 (long) steps
STEP 1 –
Initial diagnostic casts are made along with discussion about patient
restorative and esthetic goals
STEP 2 –
Diagnostic wax up of these goals is made and includes:
-Pontic shape, size, contour, and relation to the ridge
-Incorporate any changes to the current esthetics and function
STEP 3 –
This wax up then can be used with a putty matrix to make a temporary
which incorporates these desired changes
STEP 4 –
Tooth preparation and temporization
STEP 5 –
Patient returns with temporaries in place and provides feedback on the
shape, length, and overall esthetics and function. Any changes to
the temporary desired by you or the patient can then be made at
this time.
Diagnostic Waxing-Systemic Approach
STEP 5 –
Patient returns with temporaries in place and provides feedback on the
shape, length, and overall esthetics and function. Any changes to
the temporary desired by you or the patient can then be made at
this time.
STEP 6 –
Once temporaries are representing desired results, a new impression is
made of the temporaries to provide to the lab. Photographs of the
temporaries with measurements are provided for the lab.
STEP 7 –
FPD created from a final impression, and using the models of your
temporaries. Definitive prosthesis is tried in and seated.
STEP 8 –
Evaulation of final product after patient has had prosthesis for a period of time
Using wax to create intended restorative contours on casts for the
purpose of
evaluation and planning the restorations. A wax replica of
proposed treatment.

Provisional Restorations
Definition:
A prosthesis designed to enhance esthetics, stabilization and/or function for a limited
period of time after which it is to be replaced by a definitive prosthesis.
Provisional Restorations
Used to assist in
determination of the effectiveness of a specific treatment plans form and
function.
Provisional Restorations – Diagnostic Potential
Provisional restorations are used in a variety of ways to
accomplish your
treatment planning as you progress
Your — can be used to verify reduction both visually,
or with small holes in the matrix to use a perio probe.
vacuum matrix
In addition to vacuum matrix viewing to assess reduction, – can be used as well with properly placed cuts and
removal to see visually or measure with a probe what your
reduction is based on your diagnostic wax up
Putty
matrixes
When significant change is occurring, — are of little use
to you. Therefore, these alternate methods of checking
reduction are helpful.

Patient is now sent home with provisionals to “test” them out.

Changes can be made in the temporary for any areas patient is not
satisfied with.
If provisionals are modified, a new impression of temps should be
taken to mount for the case when sent to the lab.
Definitive crowns will incorporate the adjustments made and the input of family and friends.
