Are NuSmile Signature crowns crimpable?
You can crimp slightly on the lingual, but it is very important to avoid a "snap fit" and seat the crown with finger pressure only. All NuSmile Signature crown performance and durability testing and studies have been done without any crimping.
How do I properly cement a NuSmile Signature crown?
For NuSmile Signature crowns use NuSmile BioCem® Universal BioActive Cement or a high quality glass ionomer cement. Completely load the crown with cement so there are no voids. The NuSmile Signature crown should have a passive fit and be held in position until the cement self-sets.
Is there something you can send me that will help me better understand the technique for using NuSmile Signature crowns? Do you have training videos available for your crowns?
Yes, we offer a technical video available on our YouTube Channel that demonstrates preparation and placement procedures (on actual patients), used for achieving the highest degree of success and efficiency when using both anterior and posterior NuSmile Signature crowns. You can access this video titled "NuSmile Signature Anterior Clinical Technique 1" from NuSmile’s YouTube channel at: www.youtube.com/channel/UCAsG3apKAwtgCPNikyXjOSQ With your first order, our DVD "NuSmile Signature Technique Essentials, Mastering Cosmetic Pediatric Crowns" will be sent to you. This DVD is also available on our web store.
Can you provide the research that has been done with NuSmile Signature crowns?
Our website contains information regarding research and studies that have been done with NuSmile Signature crowns. Stainless steel crowns have been used effectively for primary tooth restoration for many years. You can expect the same good results with NuSmile Signature crowns.
Is placing NuSmile Signature crowns the same as placing a SSC?
Similar, however NuSmile Signature crowns require more tooth reduction than for SSCs. NuSmile Signature crowns require about 20% more reduction than a SSC around the entire circumference of the tooth. The occlusal reduction is approximately 1.5mm more than for a SSC. When using NuSmile Signature crowns you will use one or two sizes smaller than for a traditional SSC. If you use the same size as you would for a traditional SSC, the restoration will look bulky and unnatural. Also, the gingival response will be poor overtime if the appropriate size is not used. Always prep the tooth to fit the crown and remember that a "snap fit" is contraindicated for NuSmile Signature crowns.
Is the technique different when placing adjacent and opposing posterior NuSmile Signature crowns compared to seating a single crown?
It’s a little different. You are going to remove approximately 2 mm off the buccal and 2 mm off the occlusal, with greater circumferential reduction as well, to get the crowns to passively seat. In all cases you will be using at least one or two crown sizes smaller than if you were using traditional SSCs. If necessary, you can remove some of the esthetic material in the interproximal/buccal and interproximal/occlusal areas on the crown with a rubber point or wheel to help with seating. You can try using a contralateral upper posterior crown for a lower restoration when there has been mesial-distal space loss. Some doctors will reduce the distal of the deciduous canine a little if necessary.
There is often space loss due to decay in the cases I treat. Can I use NuSmile Signature crowns in these cases?
Yes, but you will always need to use a crown size that fits in the space and prepare the tooth accordingly. It will usually be at least one or two crown sizes smaller than if traditional SSCs were being used, maybe more if there is space loss. This always requires preparation of the tooth to fit the crown. With lower posterior crowns, you might find that an upper contralateral crown may work best. NuSmile Signature Posterior crowns are also available in a size 1 (straight wall).
