Oxford Zircore NANO Core Build-up Material
Oxford Zircore NANO Core Build-up Material
Oxford Scientific Dental
Oxford Zircore NANO is a dual-cure, resin core build-up material reinforced with zirconia nanoparticles for outstanding physical properties, without affecting the material's ability to stack and flow.
Reinforced with zirconia nanoparticles, Oxford Zircore NANO offers high flexural and compressive strengths in both light- and self-cure mode. This dual-cure, resin core build-up material cuts like dentin, and the nanoparticles help enhance the radiopacity when it is used as a post cement. Oxford ZIRCore NANO is available in 5 mL automix syringes for simple placement onto the tooth's surface or into a post space when used as a cement. The product is available in both tooth-colored and contrast shades to help achieve optimal esthetics.
Twelve dentists, with a combined 218 years in dental practice, signed on with Dental Product Shopper to evaluate Oxford Zircore NANO. The product was tested and evaluated on its performance and convenience, including its handling and its similarity to dentin when cutting.
Performance in Action
Many dental materials claim to cut like dentin, and our evaluators put this claim to the test. In this respect, Oxford Zircore NANO performed well, scoring higher on its ability to cut like dentin than any other feature with a 4.3. A New Jersey-based dentist said, 'Great product. The 'cuts like dentin' phrase is overused in regards to buildup material, but this product truly lives up to its meaning.' Another evaluator, with 14 years of experience, said Zircore NANO 'cut very well immediately, similar to dentin.'
The automix syringe dispensing of Oxford Zircore NANO offers void-free mixing and excellent visibility within the oral cavity. Evaluators rated this delivery system, with 4 calling it excellent, 5 very good, 1 good, and 2 fair. A dentist who rated overall satisfaction as very good called it a 'great product,' to which he added, 'Fix the delivery and you will have a home run.' Another evaluator added, 'The biggest positive is the delivery system.'
Handling earned a 4.2 rating, with 3 calling it excellent, 8 very good, and 1 good. An evaluator with 16 years of experience in dentistry called 'flowability' his favorite feature, and another evaluator said Zircore NANO was 'easy to handle, cut like dentin, and was easy to place.' When asked what he would like to see improved, a dentist from California cited 'stacking.'
Oxford Zircore NANO is formulated with zirconia nanoparticles that lend the material a high flexural and compressive strength, ensuring a reliable restoration for the patient.
Three of the 12 evaluators cited immediate hardness as their favorite feature, with 1 evaluator saying this core build-up material was 'harder than most buildup materials out there.' Another evaluator added that he liked the 'ease of use immediate hardness for prepping.'
Regarding the material's depth of cure, 3 evaluators rated it as excellent, 5 rated it as very good, and 3 rated it as good. An evaluator from Washington state, with 14 years of experience in dentistry, stated 'The depth of cure seemed adequate.'
Oxford Zircore NANO's formulation results in a versatile material, which means that it can also be used as a post cement when needed, and the zirconia nanoparticles allow it to be radiopaque on x-ray.
The ability to be used as a post cement was rated by 9 of the 12 evaluators and earned a 3.7, with 1 evaluator commenting, 'If you market this as a product to cement posts, include the corresponding bonding agent in the packaging.' This same evaluator rated his overall satisfaction as excellent.
Two evaluators called the radiopacity of Zircore NANO excellent, 9 called it very good, and 1 called it good. An evaluator who rated his overall satisfaction with the core build-up product as excellent said, 'The radiopacity can be improved. It was difficult to use as a post cement.'
When asked to rate their overall satisfaction with Oxford Zircore NANO, 2 evaluators rated it excellent, 8 very good, and 2 good. The most commonly cited favorite feature was 'ease of use,' mentioned by 5 evaluators. Seven of the 12 evaluators called the material 'much' or 'somewhat better' than similar products.
