MicroZr™ Pediatric Crowns
MicroZr™ pediatric crowns is a trademark of new customized zirconia dental pediatric crowns for anterior teeth with micrometric thickness (< 100 micrometers – equivalent to hair thickness). They fit teeth as a glove not requiring any tooth preparation.
Value Proposition
MicroZr™ pediatric crowns offer essentially the possibility to apply zirconia crowns in anterior teeth without any tooth preparation, e.g., no pre-treatment, no anesthesia, no pain.
Advantages
MicroZr™ pediatric crowns are customized to tooth geometry and so thin (thin as human hair) that fits tooth as a glove. This is the best choice for children anterior teeth.
Crown Thickness
MicroZr™ pediatric crowns are much thinner than all other crowns , including porcelain crowns . The thickness of MicroZr™ pediatric crowns is less than 100 micrometers (0,1 milimeters) the thickness of a human hair. This is much thinner than all other options available in the market, usually with thicknesses around 0,7 to 1,0 milimeters.
No pre-treatment
MicroZr™ pediatric crowns avoid preliminary tooth preparation. Avoid anesthesia and pain on children and time on clinical procedures. Save time, save money, and mainly avoid pain and anesthesia to children.
Wear and toothbrush resistance
Durability of porcelain crowns is at maximum 10 to 15 years (see article). Some of the main reasons for such low durability is wear against the opponent tooth and abrasion due to tooth brushing, among other factors during chewing. MicroZr™ pediatric crowns , due to exceptional wear and abrasion resistance of zirconia (see article and article) allow a lifetime duration of pediatric crowns . No need for successive investments in new crowns. No need for appointments for maintenance and polishing. Aesthetics is preserved over time. Moreover, it is well documented that polished zirconia also preserves the opponent tooth causing them less wear than porcelains (see article).
Excellent biological behaviour
Zirconia is documented (see article) to have excellent biological compatibility being used for several other applications namely hip implants due to its superior biological properties. Its reduced bacterial adhesion/colonization properties make this material excellent as regard to adverse effects on gingival health and gum recession.
Very accurate fitting to tooth geometry
MicroZr™ pediatric crowns are customized to each tooth and fit to tooth geometry with errors less than 20 micrometers thus allowing the crowns to fit perfectly to tooth surface and be nearly imperceptible in tooth volume. Intra-oral scan is needed to tooth geometry acquisition and a patented manufacturing technique* is used to obtain high strength and high translucent micrometric MicroZr™ pediatric crowns.

Natural tooth preservation
non invasive
MicroZr™ pediatric crowns allow preservation of natural tooth including total enamel structure. There is no need to remove, partially or totally, the enamel of the tooth with the eventual exposition of dentine. The natural tooth preservation avoids eventual hot/cold sensitivity due to tooth preparation.
Excellent aesthetics
The incredible small thickness of MicroZr™ pediatric crowns, along with new high translucent zirconia materials, result in the high translucency of zirconia crowns. Gradations of colour, with different natural shades and translucencies can be tailored in each crown for each tooth aesthetics customization and natural dental tooth appearance. See article and article.
Impact, mechanical and fatigue resistance
Durability of crowns also depends on the mechanical, impact and fatigue resistance. Low impact and fatigue resistance of porcelain crowns are one of the main causes of premature failure of porcelain crowns (see article, article and article). Despite all the care, the impacts of cutlery against teeth are an inevitability. Zirconia used in MicroZr™ pediatric crowns fracture toughness is on average 5 to 10 times higher than that of porcelain crowns (see article).The same order of magnitude is found for mechanical strength, 5 to 10 times more resistant than porcelain crowns. MicroZr™ pediatric crowns high fracture toughness and strength also allow the safe handling of crowns during treatment.
Dual and Light curing cements
Translucency of very thin MicroZr™ pediatric crowns improves transmittance of light in the range of light curing resins wavelength (300 to 500 nanometers) allowing versatility in the choice of using dual and/or light curing cements. See article.
Strong bonding to adhesives
MicroZr™ pediatric crowns are manufactured with an inner pre-treated surface that assures strong bonding to adhesives. Values of shear bonding strength of 60MPa are obtained which provides a strong adhesion to enamel.
MicroZr™ pediatric crowns is a safe and secure investment in your children's aesthetics.
Avoid anesthesia and pain. Do the work quickly and make your children's smile worth.

Thin as a human air (<100 micrometers)
Due to the high potential of zirconia as a biomedical material it has undergone large developments in the last years in order to overcome its biggest limitations namely optical properties and bonding to resins.
Due to these research investments, zirconia is becoming as the material of excellence for dental applications. This is due to the set of properties that this material has in terms of aesthetics, mechanical resistance, wear and abrasion resistance, biocompatibility, ease of manufacture, biological and mechanical stability, adhesion,
among others. Moreover, notwithstanding the previous properties zirconia has still a large margin for improvements either in terms of optical properties or mechanical and fatigue properties, among others.
Due to these circumstances zirconia is expected to increasingly become the material with the highest potential to fulfil the needs of many dental applications such as implants, veneers, bridges, crowns, and prostheses.
