Intaglio Retention Band System

AffixZr™ Mechanical Retention

What makes Zirconia Kinder Krowns® different is the intaglio. During the manufacturing process, we add screw-like threads to the crown walls, which mechanically bonds the restoration to the tooth.

These threads also significantly increase the surface area for the cement to chemically bond to the crown. The chemical bond to ceramics in general is weak, therefore it is imperative to incorporate mechanical retention. This key difference has been a part of our design since Zirconia Kinder Krowns® officially launched in 2012. This integral step of the manufacturing process allows you to use glass ionomer cement and the actual crown for intraoral try-ins. This saves you valuable inventory and chairside time.

Ambidextrous (Right or Left Option)

Universal Contour = 1/2 the Inventory

Kinder Krowns are available in two contour options: Contoured (Rights and Lefts) and Universal (Ambidextrous).

Universal crowns were precisely designed to be used as a left or a right. For example, tooth letters S and L will be restored with the same crown labeled DL (lower first primary molar). The biggest benefit this product brings to your practice is maintaining half the inventory, as well as half the initial investment.

Due to the overall contour of our universal design, you will also prep less tooth structure to achieve a passive fit over contoured zirconia pediatric crowns. Universal Kinder Krowns are our most popular option.

Length Preference

Regular or Short Length Option

Kinder Krowns are available in two length options: Regular and Short..

With Kinder Krowns, you have options. Anterior Kinder Krowns are available in two lengths, regular and short. Regular length is equivalent to regular length pre-veneered Kinder Krowns and short length is approximately one millimeter shorter. The majority of Kinder Krowns users prefer our short length.

Space-Loss / Back-to-Back

Mid-sized™ Crowns (Narrowed Mesiodistally)

Kinder Krowns Kits include regular and mid-sized Crowns.

Regular (full sized) posterior crowns were designed to be consistent in size with standard pediatric crowns. The mid-sized crowns mimic the shape of squeezed SSCs and are used when you are placing crowns back-to-back or if your patient has experienced space-loss. Mid-sized posteriors are available for both first and second molars. A mid-size option is also available for cuspids.

Unique Surface Treatment

Polished and Glazed Finish

Prior to applying the glaze layer on our crowns, we finely polish all areas that come into contact with the opposing dentition. This creates an incredibly wear-kind surface. In fact, in the most recent wear study featuring all the major pediatric crown brands, Zirconia Kinder Krowns we the least abrasive zirconia pediatric crown (by a long shot). Another, equally important reason to take a dual approach is aesthetics. Simply polishing zirconia creates a pearlescent, reflective and iridescent look, which is far from natural. In adult dentistry, we glaze zirconia crowns because it allows the restoration to adsorb colors and light (rather than reflect).
