What is Zirconium?
Due to its high tensile strength, tissue friendliness and low grain diameter, zirconia has started to be used as ceramic implant and abutment material in dentistry, core material in fixed restorations, post-core material and orthodontic brackets. The introduction of zirconium ceramics has paralleled the development of computer-aided design (CAD) and computer-aided manufacturing (CAM) technologies.
Where is Zirconium Teeth Used?
– Hereditary structure discoloration in advanced (antibiotic, fluorine, etc.) discolorations that do not yield results with methods such as bleaching,
– As an alternative to wire treatment in patients with orthodontic (crowding) problems,
– In teeth with excessive material loss that cannot be filled,
– People with metal-supported bridge-crowns (veneers) in their mouths,
– In fracture restorations that cannot be fixed with composite fillings,
– In the correction of old fillings whose color and structure have deteriorated,
Advantages of Zirconium Crowns
Zirconium porcelains are semi-light-permeable like natural tooth enamel. Therefore, they reflect some light and absorb others. Thanks to this light transmittance feature, the closest appearance to the natural tooth can be obtained.
– Since zirconium crowns have the light permeability characteristic of natural teeth, a depth and vitality emerges and an aesthetic appearance close to natural teeth is provided. However, metal-supported porcelain, even if it is very well made, reflects the dull and artificial appearance of metal metal and white covering material applied on metal, causing aesthetic problems.
– In gingival recessions, metal-supported restorations create a gray appearance in the parts that connect with the tooth, while such an appearance does not occur in full porcelain restorations even if the gingiva is removed.
– Since metal is not used in the infrastructure, dark lines do not occur at the junction of the gingiva and the restoration.
– The risk of allergy to some metals (nickel, etc.) in the metal alloy used in the infrastructure is eliminated.
– Since they are bonded with special cements, they adhere better to the tooth on which they are placed, and their colors appear more natural due to the properties of the cements.
