4 Types of consistencies of wax used for restorative art
i. Firm wax (wound filler)
ii. Medium wax (derma surgery)
iii. Soft wax (surface restorer)
iv. Lip wax
used to fill large cavities or model features
Firm wax (wound filler)
– used as a restorative wax
Medium wax (derma surgery)
soft, pliable wax used to fill shallow depressions
Soft wax (surface restorer)
soft wax usually tinted, used to correct lip separations and surface the mucous membrane
Lip wax
Firm Wax
- Used to recreate facial features such as the nose or ear.
- Used to fill large cavities and model features
- Will hold its shape once molded
- Least adhesive of any of the waxes
- Basket weave suture is quite often used as a base for firm wax reconstruction
- When restoring deep cavity excisions, its used to fill the cavity to within approximately one-quarter inch from the surface where a soft wax is then used
Medium Wax
- Softer than firm wax and often substituted for firm wax
- Adheres to tissue and will hold its shape once molded
- Easily softened by manipulation in the hand or with a blow dryer
- When warmed can be smoothed to a very fine layer which makes it suitable for shallow surface restoration
Soft Wax
- Can be applied in a very thin layer, suitable for the repair of minor abrasions/razor burns/suture incisions/surface layer of wax in a deep cavity repair
- Quite often used as a lip wax
- Can readily accept cosmetics and the pore effect can be recreated without the wax being damaged
- Used to seal puncture sites due to hypodermic building
- Manufactured in various skin colors
Lip Wax
- Most adhesive of the waxes
- Usually rather translucent but is tinted in various warm hues
- Can be mixed with cosmetics to recreate the surface contours on the mucous membrane
- Used to correct lip separation that has occurred due to dehydration
- Applying a small amount of lip wax to corners of the mouth can create the illusion of a shortened line of lip closure
- Primary among them is that the underlying tissue must be thoroughly embalmed making it firm and dry
Lip Wax (cont)
- Ideal waiting time before applying wax is between 8 and 10 hours after the embalming procedure
- Small areas such as abrasions, fever blisters, skin slip areas, and 2nd degree burns, the tissue can be injected hypodermically using a cavity fluid or phenol solution
- Moist surface areas should be covered with phenol or a cavity pack to dry up the moisture
- Quick drying liquid sealer, such as super glue is preferred although such sealing agents as hobby cement, clear nail polish, or rubber cement can be used
- Pore effect can be created in the wax by using a damp paper towel, damp gauze, or damp terry cloth
- Some restorative artists prefer stippling
3 Most Common Methods of Wax
- Cosmetics under wax
- Cosmetics mixed with wax
- Cosmetics over wax
Cosmetics Under Wax
- If cosmetics are to be applied under wax they must be liquid, spray or water-based cream.
- Choice of which cosmetic to use should be determined by judging which will cover any discolorations
- Spray or water-based cream will usually cover discolorations better than the liquid
- Liquids, sprays, and water-based creams will dry sufficiently to allow wax to be applied over the cosmetic whereas an oil-based cream will not
Cosmetics Mixed Wax
- Liquid or cream cosmetics can be mixed with wax to match a person’s complexion color
- Sufficient amount of wax is softened and cream or liquid cosmetic is worked into the wax in order to match skin tones
- Prudent to begin with lighter color first and add more cosmetics (small amount at a time) until desired color is obtained
Cosmetics Over Wax
- Most common technique used to apply a cream cosmetic over the wax
- Restorative wax is applied to the traumatized area
- Simulated skin texture pores wrinkles should be completed before cosmetics are applied
- Lightly brush cosmetic over the wax and stipple blend to surrounding complexion color
Softening Wax
o Manipulation by kneading in hand
o Adding cream cosmetic or massage cream
o Place in warm water
o Hold under blow dryer
Firming Wax
o Place in refrigerator
o Mix with cornstarch
o Mix with talcum powder
Wax Restoration
o Tissue must be firm and dry prior to wax
o Moist tissue not thoroughly embalmed will inhibit the ability of wax to adhere to surface and impair the effectiveness of restoration
Methods of Firming Tissues
o Hypodermic injection or surface compress of cavity fluid or phenol cauterizing solution may be used then firmer wax is desired
___ is least adhesive of any of the waxes whereas ___ is most adhesive of the waxes
