Modeling Techniques

Introduction•P

rocess involved a pliable material such as wax or clay.

•Forms are three dimensional and involve partial or complete construction of a feature

Feature, Location, Size, Form•S

ize and form must be accurate as well as location for an realistic restoration

•Size involves length, width, projection– Length is the vertical measurement– Width is horizontal measurement– Projection is the amount it extends from the surrounding area

•When beginning to model a feature, always measure desired width and length and mark them on modeling material or work surface

•Size can easily become distorted as you become engrossed in task

•Reproduction may be perfect, but if size is wrong the feature is incorrect.

Measurements•I

t is imperative that correct measurements be obtained.

•It is imperative that once correct measurements are derived that they are maintained.

•Measure frequently to ensure compliance.

Influence of Profile•P

rojection is typically hardest feature to reproduce.

•Shape of profile is noted by observing carefully

•Careful attention to profile will provide important information

•Prior to recreating profile, note the width.

•Appropriate thickness of wax can be selected for restoration

•Accurate measurements of the most prominent points of projection and depressions should be made

•Measurements are transferred to modeling medium.

Varied and Distance Viewing•R

eview recreation from different angles throughout restoration.

•Working from one view will easily result in distortion of feature or entire restoration

•Working only in close proximity will result in distortion

Roughness of Formative Work•E

arly on, do not be concerned with smoothing all the surfaces

•First, achieve accurate dimensions

•Smoothing early on wastes time (and stamina!)

•Smoothing is easily accomplished with brush and proper solvent.

Surface Detail and Contour•S

urface Detail and Contour make a feature more realistic

•Greatest fault to restoration is flatness. – Pores, wrinkles, furrows will reduce the flat

appearance

Wrinkles/Furrows•U

se a blunt edged instrument or ligature

•Cover area with plastic wrap

•Press into plastic wrap

•Plastic is carefully peeled away

•Softening can be accomplished with brush and solvent

Pores•S

tipple Brush, Citrus Peel, Dampened Paper Towel or Gauze

Rest Periods•T

ake breaks, this keeps you sharp and makes for a more accurate restoration.

Isolated Reproductions•P

lease review the Klicker Text from p.67-p.76 for detailed photographs of restorations.

•There is also a video produced by Professor Gary Sokoll that shows you step by step how to do wax reproductions.
