By NuSmile Staff n Since its founding in 1991, NuSmile Crowns has sold more than 4 million preformed esthetic pediat- ric crowns worldwide. The company offers both Signature® pre-veneered, tooth-colored, stainless-steel crowns and NuSmile ZR zirconia crowns. NuSmile provides free zirconia try-in crowns to avoid saliva contamination and ensure proper bonding. In 2014, NuSmile innovated yet again, launching BioCem™ Univer- sal BioActive Cement, a biologically active cement designed for pediatric use. BioCem interacts with dentin, delivering a beneficial effect to the tooth structure while also exhibiting antibacterial properties. It enables bio-mineralization by releasing both calcium and phosphate. While glass ionomer (GI) and resin-modified glass ionomer (RMGI) cements deliver some bioactiv- ity through fluoride release, these cements have been known to cause sensitivity and exhibit washout at the margins over time. According to Dr. Ray Stewart, professor of pedi- atric dentistry, University of Cali- fornia San Francisco (UCSF) Medi- cal Center: “While fluoride is very effective in promoting the reminer- alization of enamel, its effects are less pronounced in carious dentin, where calcium and phosphate are both necessary for apatite formation and integration. Resin cements have the same limitations, and recent stud- ies have also linked resin cements to the role of MMP activation in car- ies progression and cement-to-dentin bond stability.”1 In contrast, according to the com- pany, NuSmile’s BioCem is the only cement — bioactive or otherwise — that releases calcium, phosphate and fluoride ions while also forming hydroxyapatite. A scientific study has documented BioCem’s ability to facilitate the formation of hydroxya- patite, which is available to integrate withandreplenishthedentin.Inaddi- tion to exhibiting bioactivity, BioCem is biocompatible with the oral envi- ronment, containing no HEMA, BPA or BisGMA. BioCem’s many biological benefits do not require compromise of per- formance, according to the company. Its bond strength to zirconia and stainless-steel crowns is superior to traditional GI cements,2 and it is also easy to handle, with a quick self-set time of two minutes. Excess cement at the margin can be tack cured with a curing light during the initial set- ting period and quickly cleaned up. Final cure can also be accelerated for zirconia crowns with a curing light, making BioCem well-suited for both zirconia and stainless-steel crowns. References 1.
