16 Nov Dental veneers – Zirconium or E-max?
Dental veneers emerged in a world besieged by the image of endless youth and beauty, in order to fulfil people’s wish to have a perfect smile. The media stories in which a major aesthetic change is immediately followed by success and happiness amplify the wish to improve one’s appearance, to raise self-confidence and self-respect of patients that visit the aesthetician.
The expected results are attained only through customised solutions and thorough doctor/patient communication, since each case has its own peculiarities and each material has its advantages and disadvantages.
Here are several aspects that make the difference between the veneers with ceramics of zirconium oxide and veneers with ceramics on E-max (pressed lithium disilicate ceramics):
1. Zirconium – better for devitalized teeth with changes in colour, E-max – on vital teeth.
Drilled veneers made of zirconium oxide are opaquer and they do not allow the transfer of light and darkened colour of the support tooth. This way, a final lighter shade may be obtained more easily.
E-max veneers have a higher degree of translucence and brightness and they are recommended for vital teeth. If the tooth is devitalized and requires a crown reconstitution, this must be made of zirconium and may have an E-max ceramic crown added.
2. Zirconium is more indicated in the case of higher masticatory forces.
Dental veneers made of zirconium have the highest resistance to fractures, outranking both the feldspathic and E-max ones. The resistance to fractures and optical properties of ceramics are inversely proportional.
3. E-max is better for small, symmetrical preparations.
Dental veneers made of pressed E-max ceramics may be adhesively cemented on teeth, unlike the zirconium ones. They may be 0.3 mm to 0.8 mm thick, also bearing the name of “prepless veneers” in certain situations (small, microdontic, conical). This way, the lower resistance to fractures, by comparison to that of zirconium veneers, is compensated by a better level of adhesion.
4. Absolute contraindications, for dental veneers made of both zirconium oxide and E-max, are as follows:
-devitalized teeth with simultaneously present proximal (lateral) and root fillings.
-teeth with severe position changes, in the absence of orthodontic treatment.
In such cases, a dental crown must be used instead of a veneer, since the risk of fracture or detachment is extremely high.
