What you love, just got bigger.
After more than 30 years as a leading manufacturer of esthetic pediatric dental crowns, Kinder Krowns® has leveraged its vast dental design knowledge and customer insight to create a crown that’s going to be big, literally. At the AAPD Annual Meeting in Chicago, Kinder Krowns® is launching : XL Posterior Zirconia Kinder Krowns®.
Since introducing Zirconia Kinder Krowns® several years ago, many of our customers have asked for a pre-formed posterior crown that can be used to restore 6 year molars. One resourceful customer restored number 30 with a large sized second molar on a patient with Dentinogenesis Imperfecta and it worked beautifully. After identifying this need, we developed XL Posterior Kinder Krowns®. Sized comparable to pre-formed adult first molars, XL Posterior Kinder Krowns® provide your patients a long-term temporary esthetic solution until a custom crown can be placed.
XL Posteriors are available in our universal contour, which was designed to be used as a left or a right (ambidextrous). For example, tooth numbers 30 and 19 will be restored with the same crown labeled “EL” with the corresponding size from 7.5 through 11. The biggest benefit universal contour brings to your practice is maintaining half the inventory, as well as half the initial investment.
The most appropriate code for billing XL Posteriors is D2740 – crown – porcelain/ceramic. In 2018 the code description was revised, removing the word “substrate” and is to be used for any porcelain or ceramic crown placed in the adult dentition. It took several years for the ADA to issue a code for preformed zirconia pediatric crowns. Until a code specific to preformed ceramic crowns for permanent teeth is issued, it seems as though D2740 is the most appropriate code choice.
As part of our commitment to innovation and customer satisfaction, we are constantly developing ways to improve our products for our clients. Much of our product development process incorporates customer feedback. Based upon user feedback, we’ve made several design changes since Zirconia Kinder Krowns® hit the market in 2012. We are currently on our 4th Generation Zirconia Posteriors and 3rd Generation Zirconia Anterior Kinder Krowns®.

You have a choice of which esthetic pediatric crowns you’re using in your office – once you give Kinder Krowns® a try, we know you’ll make the switch, if you haven’t already.
Patient Specific Kinder Krowns®:
Prefabricated pediatric crowns have come a long way. There are so many viable options on the market, and they make most cases easier to tackle than in days gone by. But the clientele that pediatric dental offices have can make things challenging even with all these options available.
Patients may have larger teeth than what many manufacturers offer (see the article on XL crowns in this newsletter)! They may have shades that the standard pediatric restorations won’t blend with. Maybe they have special needs, and you really just have one shot to get in and do the dentistry needed, and the off the shelf products won’t work.
Kinder Krowns® has options for all sorts of cases like this. Being a conventional restorative dental lab, we have solutions for anything you can throw at us. If you’re fortunate enough to have access to a digital impression system, that opens up the options even more.
We’re able to work with most of what you can supply us with, whether that’s a study model, digital x-ray, even just measurements of the existing teeth (or spaces). The most satisfying cases for us are the most challenging. Challenge us!
These patient specific crowns take many different work flows. But they’re all pretty simple! Much of that depends on what information you can give us.
With a little planning, and just a few dollars more than a regular Kinder Krown®, patient specific crowns can make you look like a rock star.
Zirconia Pediatric Crowns
Some of the most frustrating conversations we have are when we have to set the record straight with a dentist who has been misinformed by a competitor or colleague. It’s funny how word travels, and how things take on a life of their own. It shouldn’t surprise us considering the social media place we’re in right now.
The myths that are traveling the pediatric dental arena gain a foothold, much like the Loch Ness Monster tale. Like the old telephone game, exaggeration abounds as these stories ferment.
So, what are these tales to which we are referring? Here’s a few that we’ve seen spun in the marketplace.
Probably the most popular and also the one that is not thoroughly explained is that of the need to keep the zirconia bonding surface free of contamination. While this may be true with some of the smooth-walled restorations on the market, it’s not an issue with Kinder Krowns®. The screw-like threads on the internal surface of our crowns give you what you need for trouble free restorations – mechanical retention. When you injection mold a crown, mechanical retention is impossible. See related article “Get A Grip” in this newsletter.
Autoclaving. This is one of the funniest myths we’ve heard lately. There is actually a company selling zirconia pediatric dental restorations saying that you cannot autoclave zirconia. They are telling dentists that it can change color? Yikes, back up the trolley! A little education on the processing of zirconia. After milling (or injection molding for that matter), zirconia has to be sintered which shrinks it and hardens it to the durable material it becomes. The sintering process is done at temperatures from 1200 – 1600°C. Our glazing process brings the material once again up to over 900°C. How in the world is anyone supposed to believe that putting zirconia in an autoclave at 100°C could alter any characteristics of the zirconia material? Again, a bizarre, and definitely misleading statement.
Size matters. Another claim by a competitor is that milling creates crowns that are not the same size. What? Every puck has a shrinkage factor built into it that is extremely precise (a thousandth of a percentage point). The CAM software calculates that when it mills. This is the reason GP’s love the fit of zirconia. Precision!
Milling weakens the zirconia. This one is way out of outer space, Mars, Pluto maybe, or straight out of Uranus (sorry about the pun there). Strength studies have proven time and time again that if handled properly throughout the process, milling pediatric restorations are as strong or stronger than any manufacturing process. In fact, in a recent durability study Zirconia Kinder Krowns® outperformed all other brands tested in both controlled and artificially fatigued groups.
We have all been taken in, at some point or another, by a modern myth. Fortunately, we’re here to help set the record straight. If you are wondering about any other statements or claims that seem kind of fishy, feel free to contact us. The truth, as they say, shall set you free.
Get a Grip on Zirconia Pediatric Crowns:
The future without try-in crowns is NOW!
You have most likely seen aggressive propaganda over the past few years touting a pink crown, specifically used for intra-oral try-ins to combat “contamination”. First off, “contamination” leads the audience to believe that zirconia pediatric crowns cannot be disinfected. Which is false, they are 100% autoclavable. Zirconia can withstand incredibly high temperatures without affecting the structural integrity, shade or finish. To put things into perspective, after applying the ceramic glaze, we fire Zirconia Kinder Krowns® at a temperature of 900°C (considerably higher than the standard autoclave temperature of 212°F).
The truth behind the pink facade is that injection molded crowns lack mechanical retention. They cannot contain undercuts and rely purely on chemical adhesion. Since they lack this critical feature, you are required to use a separate crown for intraoral try-ins and a special cement. Even after following this recommended protocol, clinicians continue to have issues with debonding. The zirconia we use in dentistry is zirconium dioxide, and the oxide part is where bonding happens. It is the functional phosphate groups that bond to the zirconia. After a crown is tried into a patient’s mouth, the bonding sites on the zirconia crown become occupied by phosphate groups found in the saliva.
What makes Zirconia Kinder Krowns® different is the intaglio. During the manufacturing process, we add screw-like threads to crown walls, which mechanically locks 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.
One of the most common questions we are asked by new and potential customers is “After intra-oral try-ins, how do you clean Zirconia Kinder Krowns®?” For years our customers have simply been cleaning the intaglio with water spray to remove blood and debris. If they find dried blood that’s not easily removed, they use a cotton swab with alcohol to clean it. The mechanical retention eliminates the need for a second set of crowns that are only to be used for try-ins.
If you’d like to take things a step further, a recently discovered cleaning method is to wipe the intaglio of the crown with gauze that is soaked in 5% sodium hypochlorite. After wiping the inside of the crown, rinse with water, followed by air drying. The concept is that NaOCl breaks down the phosphate groups from saliva and blood, so they can no longer bond to the crown’s surface.
As Todd Mayclin, CDT, CEO best put it, “Our customers tell us that they want things simple. What’s simpler than using the actual crown you will be cementing?” If you’d like more information or a free sample kit, call 877-557-6967 or visit our booth at the 2019 AAPD Annual Session in Chicago.
