Modeling Technique

Question 1

The process of constructing a solid three dimensional from by many additions of a pliable material such as restorative wax.

• The feature from a mass is impractical

Answer 1

Modeling

Question 2

The linear form of the head or features.

Answer 2

Silhouette

Question 3

Turn the model and the construction until a line is visible.

Answer 3

Use of the solhouette to accurately model surface form.

Question 4

• First learn the concepts of modeling as taught.
• As we progress each of us uses our own technique.
• A thorough knowledge of stuctural relationships and the norm of each feature will help us to recognize any variation and recreate it.
• Only when we have developed our own technique can we safely “borrow” from others.

Answer 4

Development of technique

Question 5

Any support or framework employed in a restorative treatment.

Answer 5

Armature

Question 6

• Splints
• Wire
• Certain sutures
• Cotton saturated with:
  
  • Plaster of paris
  • Liquid sealer
• Cardboard
• Pliable metal plates

Answer 6

Types of Armatures

Question 7

Never begin modeling without adequate preparation first.

• Analyze the situation
• Anticipate problems
• Determine a plan of operation

Answer 7

Analyzation Before Modeling

Question 8

When modeling, you determine this and stay within their limits.

• Involves three dimensions.

Answer 8

Size

Question 9

1. Length
2. Width
3. Projection (most difficult)

Answer 9

Dimensions of Size

Question 10

Correct spatial relationship of features.

Answer 10

Position

Question 11

• Bone structure
• Facial proportions (also determines size)

Answer 11

Useful in determining position

Question 12

The external shape

Answer 12

Form

Question 13

• Knowledge of structural relationships
• Object analyzation
• Manual coordination

Answer 13

Achievement of Form

Question 14

1. Exact measurements of length and width must be marked on the wax surfaces.
2. Long shallow lines are marked with a spatula.
3. These lines can be erased by rubbing a finger over them when the modeling is completed.

Answer 14

Landmarks of Size

Question 15

Whenever 2 or more measurements are made in the same direction, be sure they are made from the same point.

Answer 15

Measurements in one direction

Question 16

1. The model should be to the side or above the modeling.
2. Close one eye and model by sighting at arms length.
3. Profile viewing requires the parallel location of the model.
4. Refer to the model many times.
5. View the model and waxwork from the same point.

Answer 16

Position of The Model

Question 17

• Visualize the feature as a geometric form.
• Parts of the feature may resemble a form.

Answer 17

Configuration to a pattern.

Question 18

• Ear - Wedge
• Glabella- Triangle

Answer 18

Visualize the feature as a geometric form

Question 19

• Outer rim of the ear - ? (question mark)
• Closed eye- Almond
• Line of closure of the lips- Hunting bow

Answer 19

Parts of a feature may resemble a form

Question 20

Modeling speed will stay the same, the difference is:

• Fewer mistakes are made as we learn.
• Correction of errors is time consuming.

Answer 20

Progression

Question 21

The greatest amount of work is done with these.

Answer 21

The hands

Question 22

These are required for inexcesssible areas.

Answer 22

Instruments

Question 23

Use one of these at a time, supporting with the other when necessary.

Answer 23

Hand

Question 24

Try to work at this distance.

Answer 24

Arms length

Question 25

This can result from being heavy handed.

Answer 25

Distortion of the features

Question 26

* Construct each feature in its rough form. * Do the smoothing at one time- when the feature has its form.

Answer 26

Rough Modeling

Question 27

Correctly build the mass, then worry about small details, depressions, concave areas (Example: nares)

Answer 27

Construction of large masses

Question 28

* By additions * By reductions * May people prefer to just "start over" * You can slowly reduce the model- trim away the wax while maintaining the form.

Answer 28

Surface Corrections

Question 29

To observe the surface as a linear form.

Answer 29

Modeling by silhouette

Question 30

Example: Nose- get the correct profile first, then proceed.

Answer 30

Modeling first by profile.

Question 31

Importance: The form is seen when viewing the deceased.

Answer 31

Modeling the bilateral form second.

Question 32

* It is nearly impossible when the body is on the table. * Inverted position- reveals unnoticed details.

Answer 32

Modeling from Direct View

Question 33

* Keeps the eyes from becoming fatigued. * Modeling will be accurate. * Distance viewing is helpful. * Move the table to change light direction and create shadows.

Answer 33

Frequency of Changed Viewing

Question 34

* These are very important * Will reduce eye fatigue. * When returning to the work area study your subject from a distance.

Answer 34

Rest Periods
