Zirconium oxide has emerged as a revolutionary material in the field of dentistry, offering exceptional strength, durability, and natural aesthetics. To further enhance the visual appeal of zirconium oxide restorations, dental technicians employ the technique of coloring with liquids.
This article explores the process of coloring zirconium oxide restorations using liquids, highlighting its benefits and significance in achieving superior dental aesthetics.
Zirconium oxide, also known as zirconia, is a ceramic material widely used in dental restorations due to its remarkable mechanical properties and biocompatibility.
It is a preferred choice for dental crowns, bridges, and implant abutments, providing patients with long-lasting and aesthetically pleasing dental solutions.
While zirconium oxide exhibits excellent strength and durability, its natural color is often not an ideal match for natural teeth. bandar togel online This discrepancy in color can result in restorations that appear unnatural and stand out, compromising the overall aesthetic outcome.
To address this issue, dental technicians utilize coloring techniques to achieve a seamless blend between zirconium oxide restorations and the patient’s existing dentition.
Coloring zirconium oxide with liquids involves the application of specially formulated coloring agents to achieve desired shade variations. These coloring liquids are composed of pigments and dyes suspended in a solvent base, allowing for precise customization of the restoration’s color.
The process begins by preparing the zirconium oxide surface for coloring. This involves cleaning the restoration and ensuring its surface is free from any contaminants. The restoration is then placed in an oven to ensure proper adhesion of the coloring liquids.
Next, the dental technician carefully selects the appropriate coloring liquid based on the desired shade and characterization required for the restoration. The liquid is applied evenly to the surface of the zirconium oxide using a brush or spray. Multiple layers may be applied, with each layer being cured in an oven to ensure optimal color stability.
Coloring zirconium oxide restorations with liquids offers several advantages:
— In addition to the DD Basic Shade System, which is applicable to all types of zirconia, there are the specially adapted liquid series Pro Shade C and Pro Shade Z.
Since the materials differ in their chemical composition, the liquids are specially tuned to an optimal color effect. Dyeing zirconia with coloring liquids is a patented process, therefore only coloring white blanks is allowed.
– Dental Direkt coloring liquids should be stored in a tightly closed container, ideally the original container, at max. 25 °C are stored. With open storage of the liquids, aqueous parts could evaporate. The higher the ambient temperature, the faster this process goes.
By reducing the aqueous liquid base, the coloring ingredients increase in proportion. This can lead to darker color results in the colored restorations.
If open vessels, such as the DD Color Box, are used to process the liquids, they should be kept as cool as possible and covered in between. After use, the dyeing solutions must be replenished as quickly as possible in the tightly sealable storage container.
— The different coloring liquid series are specially adapted to the chemical composition of the other DD medical zirconia. Various amounts of the elements, like Al2O3, contained in the microstructure cause a different color formation.
The composition and amount of coloring oxides in the other series are adapted to this chemical composition. The coloring oxides used are identical in all series.
— A mandatory indication of the immersion time is not possible because the color perception is very individual. Dental Direkt only gives a recommendation for the immersion time of 20 seconds.
The color development also depends on the construction, the longer I dive the work, the greater the difference in color between massive Pontix and thinner copings. One way to influence the color effect on the Pontix is to block the base. For the individual optimal result, trying is necessary.
— The pre-drying should be done in a separate oven and serves to fix the color on the white constructure. By using a separate oven, such as a fan-assisted comestic oven, the contamination of the sintering furnace and thus discoloration of later sintered constructions should be avoided.
