What are dental waxes?
Dental wax is a substance most often made from paraffin, beeswax, or carnauba wax. Dental wax’s primary use is to protect the mouth’s sensitive areas such as the gums, lips, and cheeks’ lining. It is usually transparent and unnoticeable when used.
What are the components of dental waxes?
Composition of Dental Waxes
- The primary components of dental waxes are derived from synthetic waxes and natural waxes (hydrocarbons of the paraffin and the microcrystalline groups, carnauba wax, candelilla wax, and resins).
- Gum dammar, or dammar resin, is a natural resin.
What are the different types of dental wax?
CLASSIFICATION BY USE:
- PATTERN WAXES: Paraffin, micro-crystalline wax, ceresin, carnauba, candelilla, beeswax.
- CASTING WAXES. They are used to make:
- BASE WAX FOR THE PLATE. It is used for:
- WAX FOR BOXING.
- GENERAL USE WAX.
- MOUNTING WAX.
- CORRECTIVE WAX.
- WAX FOR RECORDING BITES.
What are the properties of wax are needed to meet the dental requirement?
The desirable properties of baseplate wax could be stated as follows:-
- High strength and rigidity at mouth temperature.
- Wide softening range above mouth temperature.
- Easily moldable in the softened state, without flaking, cracking or tearing.
- Low thermal contraction.
What are the properties of the wax used?
Scientists consider “wax” to be a generic term for classifying materials that have the following characteristics:
- Solid at room temperature; liquid at higher temperatures.
- Primarily hydrocarbon in structure.
- Water repellent; insoluble in water.
- Smooth texture; buffable under slight pressure.
- Low toxicity; low reactivity.
Why is wax pattern important?
The accuracy of wax pattern is of major importance for obtaining a well fitting casting. Dimensional changes in wax pattern occur on the die and during removal of pattern from the die.
What are the uses of dental waxes?
What Is Dental Wax Used For? Dental wax is used for tooth impressions, casting of teeth duplicates and tooth models. It is also used to protect braces. People with braces can take a bit of the wax, warm it up in their hands to make it soft and press it on sharp wires in their mouth.
What is the structure of waxes?
Essentially, waxes consist of a long-chain fatty acid linked through an ester oxygen to a long-chain alcohol. These molecules are completely water-insoluble and generally solid at biological temperatures.
What is the density of wax?
approximately 0.9 g/cm3
Paraffin wax is a white, odorless solid with a typical melting point between approximately 115 and 154 °F (46 and 68 °C) having a density of approximately 0.9 g/cm3. Wax has low thermal conductivity, a high heat capacity, and is insoluble in water.
Which processing waxes are soft?
Boxing wax: a soft, pliable wax used for forming a wax box around an impression before it is poured with gypsum.
What is wax elimination?
9 Wax elimination Wax elimination: it is a process of eliminating wax from a mold into which acrylic resin will be packed by placing the flask in hot water after setting of the flask plaster. Flush the mold with a clean hot water to remove all traces of detergent solution.
What is a dental wax impression?
It is a computer-generated process that will enable your dentist to capture a clear and accurate impression of the soft and hard tissues of your mouth with optical devices. With a digital scan, dentists can prepare a wax model for your dental restorations that will be accurate and fits well.
