To apply for the FDA import permit, takes time and cost much money. Hence, popular Brand of Diamond Burs are imitated so that it can be imported and be sold freely within the Dental Market without FDA hassle.
Generally, the import for the Japanese brand of Mani Diamond Bur with its smallest Diamond head (e.g. BR 41, BR 46 etc.) are exported at US$ 0.60 per piece. The larger and longer Diamond head will cost more. One do wonder, when emails offer for the mentioned brand of Diamond Bur with 1 Box of 3-pieces packing has such low cost ???
The other reason for the Brand imitation is of course, just purely having a much lower quality Diamond Bur to imitate a better brand so that profit or sales could be increased many fold.
Hence, as mentioned in previous post, Dentist today who are brand loyal, do indeed has a hard time in evaluating the genuine Diamond Bur from the imitation Diamond Bur. Buying from a reliable supplier source and or changing brand loyalty has become the trend then.
