FAQ
FOR DENTAL CAD/CAM MILLING BURS
Dental CAD/CAM milling burs are high precision comsumbles for dental milling machines to mill dental restorations, such as crown, bridge, inlay/onlay, veneer, abutment, all-on-4, RPD, bar, etc. for zirconia, PMMA, glass ceramic, PEEK, titanium, CoCr, composites, etc dental CAD/CAM materials.
Diamond coating is a ultra-thin CVD(Chemical Vapor Deposition) coating for zirconia milling burs to make the lifetime of milling burs much longer and mill more powefully with higher precision, the milling quantity of crowns will increase up to 500-1200 units, depends on the quality of diamond coatings.
Diamond coating or DC zirconia milling burs could last for 500-1200units of zirconia crowns or equivalent to 80-300 working hours, depending on the diamond coating quality, milling burs manufacturer, zirconia block hardness, milling machine performance, CAM strategy, working conditions, etc.
DLC(Diamond Like carbon) is not a real diamond coating, the lifetime will be much shorter, around 100-150 units of crowns, ideal for PMMA and zirconia restorations milling, while DC(Diamond Coating) is higher precision and much longer lifetime, around 500-1200 units of crowns.
VPT Tools, also called Shenzhen VPT Tech Co., Ltd, is a professional manufacturer of dental CAD/CAM milling burs for dental laboratories since 2017 in China, with annual sales volume of more than 600,000 pieces of dental milling burs around the world. The main products are DC zirconia milling burs, glass ceramic milling burs and titanium milling burs.
DLC zirconia milling burs could mill up to 100-150 units of crowns, depends on the material performance, CAM strategy, milling machine performance, etc.
Glass ceramic/Emax/Lithium disilicate milling burs could mill up to 80-100 units of crowns or equivalent to 1000-1500 mins, depends on the glass ceramic block hardness, CAM strategy, milling liquid quality, milling machine performance, etc.
Titanium milling burs could mill up to 1500-3000 mins, or equivalent to 25-50 hours or 100-120 premill abutments, or 6-10 implant bar or implant bridge, etc, depends on the use of milling liquid or pure oil, CAM strategy, milling machine performance, spindle power, coating type, etc.
PMMA milling burs could mill up to 100-150 units of crowns, depends on the coating (Non-coating, rainbow coating, DLC coating), PMMA block hardness, CAM strategy, milling machine performance, etc.
Original milling burs are provided by the dental milling machine companies, more compatible and stable, while third pary milling burs are manufactured by the dental milling burs factory, such as VPT Tools, with the same performance and quality and even better in some situations and less cost.
