Are Sprig crowns guaranteed?
Yes. All Sprig crowns are warranted against manufacturing defects. We will always replace damaged products—no questions asked. Failure to follow Sprig’s clinical technique instructions relating to pressure and/or seating forces may result in damage to the crowns. We ask that all products to be replaced be returned so that we can evaluate the problem to ensure it doesn’t happen again.
What shades of Sprig crowns are available?
Sprig crowns come in one esthetic polychromatic shade. Unlike the competitors monochromatic crowns, Sprig crowns are hand characterized by artisans. Adding this realistic color shading allows our crowns to visually blend in with surrounding natural teeth.
What are Sprig crowns made out of?
Sprig crowns are made of solid, monolithic Zirconia, a ceramic material time-tested for its strength and durability in adult dentistry. If you have been disappointed by other products in the past, you can trust that Sprig will deliver a crown that will exceed your highest expectations.
Are Sprig crowns biocompatible?
Our Sprig crowns are the most biocompatible crowns used in pediatric dentistry. Because today’s parents not only desire esthetic crowns but also have concerns about biocompatibility, Sprig has created a crown that is free of all metals–including nickel, commonly used in stainless steel crowns. You can assure your patients’ parents that there will be no adverse reactions or side effects associated with Sprig crowns.
Can I autoclave Sprig crowns?
Yes. Sprig crowns may be autoclaved for quick turnaround without color degradation or damage to the crowns. Completely rinse and dry off with air/water spray to remove any blood and debris. If blood is dried on, crowns may be placed in a small cup with 3% hydrogen peroxide for a couple of minutes. Place the dry crowns in a clear view sterilization pouch and steam autoclave as noted in the manufacturer’s directions. Please refer to our Youtube channel for more information.
Do Zirconia crowns cause excessive wear to the opposing dentition?
No. Our NEW patent-pending Zir-Plus™ hybrid surface technology offers beautifully glazed facial surfaces for maximum esthetics while providing mirror-polished, non-glazed functioning surfaces for ultra-low wear!

What sizes of Sprig crowns are available?
Sprig crowns come in the common sizes that pediatric dentists are used to using. The Anterior Collection comes in six sizes: 1-6, while the Posterior Collection comes in sizes 2-7, similar to the traditional SSC options. In addition to the standard sizes for first and second molars and upper cuspids, we also offer Prime SL™ sizes for space loss and back to back multi-unit cases. Please note that the upper Prime SL™ cuspid crowns fit the lower contralateral cuspids perfectly.
What are SL™ crowns?
Introduced in 2014, our improved space loss crown collection called SL™ is available for first and second molars, as well as upper cuspids to restore up to 3mm space loss for the ultimate in Zirconia restorative flexibility. Because of the difficulties associated with fitting crowns on primary molars where space loss has occurred, and the inability of Zirconia to be modified like SSC’s, our patent pending SL™ crowns are narrower mesiodistally while retaining the same buccolingual measurement as our standard posterior crowns. Each SL™ crown provides approximately 1mm of space loss accommodation, for up to 3mm of space loss per quadrant.
How do I get an additional storage tray?
Anterior and posterior collection trays are included with your purchase of anterior or posterior Starter or Pro Kits. Additional trays are also available in our store here.
How long have Sprig crowns been used?
Sprig crowns have been available for sale in the USA since the summer of 2010. However, Sprig crowns have been tested in the mouth since 2008.
What code do I use to bill insurance?
There is a new code for billing; it is D2929, prefabricated ceramic crown for primary tooth.
Are there any dentists in my area that use Sprig crowns?
Yes. Please contact our office at 888.539.7336 and one of our friendly staff members will assist you.
May I schedule a “lunch and learn” presentation/discussion session?
Currently, we can only provide “lunch and learn” sessions to dentists located near our headquarters in California. We are in the process of developing educational materials and CE courses, focusing on cosmetics in pediatric dentistry. Contact us for further details. Clinical technique videos are now available on our Web site, and a clinical technique DVD will be included in your first order.
Where are Sprig crowns manufactured?
Sprig crowns are manufactured in our ISO 13485 certified laboratory in Loomis, California in the heart of the Gold Country. Support the US economy by purchasing US made products! Many of our competitors crowns are made in Asia.
What is the quality of the Sprig Zirconia?
Sprig uses only the highest quality German made Zirconia material on the market. Quality is all about particle size and uniform density of the ISO pressing of the powder. Mean Linear Intercept (MLI) is the measure of the particle size after sintering. Sprig’s Zirconia has an MLI of .22 compared to other brands that are greater than .27. Our commitment to quality means years of worry-free performance.
May I return the crowns if I’m not happy with them?
Yes. Sprig guarantees your satisfaction. However, we would like the opportunity to discuss clinical technique with you before you mail them back. Most problems dentists have with the crowns can be remedied with the use of proper clinical technique.
Do you have any videos or instructional materials explaining clinical technique?
Can I crimp Sprig crowns?
No. Sprig crowns are made of solid Zirconia that does not flex. It is very important that Sprig crowns fit passively. Because they are solid Zirconia and DO NOT flex, pushing harder will not work. Do not attempt to force a crown to fit. Excessive seating pressure may fracture the crown. The appropriate size Sprig crown should fit passively and completely subgingivally without distorting the gingival tissue. Internal Zir-lock™ grooves will “bite” the facial and lingual walls of the prep, providing a proper snug fit.
Can I make adjustments to Sprig crowns?
Yes. It is possible to adjust an Sprig ceramic crown. However, because it is ceramic and cannot be trimmed with scissors like a traditional SSC, it is necessary to use a high-speed, fine diamond with lots of water because excessive heat could cause micro-fractures in the crown’s ceramic structure. Occlusal and interproximal adjustments are not recommended, as these will remove the crown’s polish and glaze and possibly create a weak area of thin ceramic.
What cement do you recommend for use with Sprig crowns?
Sprig’s patented Zir-Lock Ultra™ technology gives you the ultimate in flexibility by allowing you to choose any cement system. With over 2x the surface area compared to other crowns, Zir-Lock Ultra™ bonds without fail to any cement. However, to prevent loss of adhesion between the cement and the dentin where moisture control is difficult, we recommend using a non-resin containing GI cement like Ketac-Cem™ for its ability to bond predictably to dentin in a wet environment.
Do I need to purchase EZPREP Diamond Burs or can I use my own?
No. Any burs may be used to achieve the required preparation. However, EZPREP Diamond Burs are specifically designed to give you the perfect prep in the shortest amount of time. For those new to Zirconia crowns, our high quality German burs will significantly shorten the learning curve saving you time, money, and frustration.
Do I need a try-in crown?
No. Try-in Crowns were an attempt by other manufacturers that lack Sprig’s patented internal retention features of Zir-Lock Ultra™ to overcome scientifically proven retention issues common with zirconia crowns. Sprig crowns with Zir-Lock Ultra™ not only simplifies the cementation process by elimination of an extra try-in step, but retention will be much stronger than with any other crown system.
What is the best method for hemostasis?
Does placing Sprig Crowns require a pulp therapy?
No. Our tooth sparing Flat-fit™ design allows preparation and seating without the need for pulp therapy required by other brands of Zirconia crowns. This is one of many key features that sets Sprig apart from the rest. It is highly recommended that you follow the preparation instructions described on the website and our Youtube channel.
What if I need to do a pulp from decay? How do I maximize retention in these cases?
Restoring teeth with extensive caries and tooth structure loss with Sprig crowns can be predictable and long-lasting. Extra space must be provided in the pulp chamber for maximum cement retention to the tooth. It is highly recommended that you follow the pulp therapy instructions described on the website and our Youtube channel.
Can I cement a band to an Sprig Crown?
Yes! Sprig’s patent pending Zir-Plus™ surface treatment allows both mechanical and chemical adhesion to the cement and band on the OUTSIDE of the crown not possible with other brands of zirconia crowns. This is one of many key features that set Sprig™ apart from the rest. It is recommended that you follow the band placement instructions described on the website and our Youtube channel.
How do I “mix” SmartMTA?
In a small area on a glass slab or mixing pad, simply wet the powder by gently incorporating the powder into the liquid until all the powder has been hydrated, approximately 30-45 seconds. The “mix” should appear shiny. DO NOT OVERMIX SmartMTA.
How do I place SmartMTA?
Once the “mix” looses its shine, immediately place in an amalgam carrier or suitable alternative and place at the operative site.
After placing SmartMTA, how long do I have to wait before proceeding with the restorative procedure?
Setting time is 150 seconds and, because there is no washout, the restorative procedure can begin immediately after.
How much liquid do I use with 1 vial of SmartMTA.
2 free flowing drops.
What factors may affect setting time?
The amount of water will modify the setting time. More water will slow the set and less water will speed the set. It is important to dispense 2 free flowing drops of SmartMTA every time for consistent results.
How many teeth can be treated 1 vial of SmartMTA.
Normally, 1 vial (.2g) is enough for 2 pulpotomies on first molars, or one larger second molar.
What accessories do I need to apply the SmartMTA with?
An amalgam carrier will easily place the material at the operative site. We recommend using a glass slab, however a paper cement mixing pad is a disposable alternative.
If using as a base or pulp cap, do I need to cover SmartMTA with another base material?
Only if using a composite resin restorative material. In this situation, a LC RMGI such as Vitrebond or Limelight may be used. GI containing (RMGI or pure GI) restorative materials can be placed directly over Smart MTA.
Can I mix with local anesthetic.
Yes, local anesthetic can be used in lieu of the distilled water. However, since two drops of liquid is the perfect amount to wet the powder, it may be difficult to dispense the same amount of local anesthetic consistently.
Can I use a metal spatula to mix SmartMTA?
No. A plastic spatula is recommended.
How do I achieve hemostasis prior to placing SmartMTA?
HemeRX pellets may be used or Sodium Hypochlorite.
How many HemeRx pellets are used at a time for optimal hemostasis?
It depends on the procedure and how much bleeding is present:
- Zirconia crown placement: 2-4 per tooth
- Pulpotomy: 1-2 per tooth
- Strip crown/composite restoration: 1 -2 per tooth
Do I need to wet HemeRx pellets before use?
Quickly dipping them in water will activate the epinephrine faster.
How long do I leave HemeRx pellets in place?
Usually 1-2 minutes for water moistened pellets. Direct pressure with a moist 2×2 gauze during this time will improve hemostasis.
What is the best location to place HemeRx pellets?
Start with one pellet on each side interproximally. If the bleeding is diffuse, an extra pellet maybe added to the buccal and/or lingual.
What instruments work well to place HemeRx pellets?
For optimal placement, use cotton forceps to place the pellets. Then, use a composite instrument to push them subgingivally.
