I'm Linlin,comes from shenzhen Myy dentallab，I've been working in dentures for 13 years.

So my experience gives me a different perspective than most people.  I know the quality can be very high and the cost savings significant for labs, as well as large- and medium-sized dental practices.

I helped several of these U.S. firms set up outsourcing programs for dental prostheses.

The key to buying high-quality crowns from China is the same as buying anything else; you get what you pay for.   If you want to pay $13 for a Chinese-made crown, you will get a very cheap and poorly made crown.   If you're willing to pay more, you can get an extremely good crown, but at a lower price than you would pay in the U.S.

It is possible for a dental laboratory or any large dental practice (cutting 60 or more crowns a week) to get very high-quality crowns from China at savings of 40% or more from what they would pay in the U.S.

How much experience do you want?   The quality is very high.   MYY dentallab is German management, training, and supervision, but significant savings are possible because Chinese labor is not as expensive.

There seem to be three main objections to using outsourced crowns from China.  One is that many dentists and labs think it is unpatriotic and damaging to the U.S. to sell or use crowns that are not made in America.  That argument has been made in the past with cars made in Japan.    It is fine if people feel that way, but globalization is here to stay and most large U.S. labs have an offshore component to increase what they offer their dentist customers.   Those labs that don't are missing an opportunity for growth that can help them take care of their employees.  More profits with the same number of employees can mean more money for training and benefits, such as constantly rising health insurance costs.

Most labs get 80% of their business from 20% of their customers.  There is little to be gained from not offering customers what they want, and that is often a lower-priced alternative.   One quality U.S. lab technician I worked with kept saying that Chinese crowns we were bringing in were as good as his.

I know my materials are approved by the FDA.

The teeth for dentures were made in China shenzhen，The Chinese labs have no interest in using substandard materials.                The key to their success is long-term relationships.  They want to keep their customers happy, and are very concerned about what they produce.

If you are buying a crown from China at $13, it probably is a low-quality product made in a sweatshop.    Making crowns is a craft.       

 It is a skilled job that requires careful and trained labor.       If the workers feel abused, they will not produce a quality product and lab owners know this.  Most workers live in dormitories and eat in company cafeterias.          But this is what they expect if they are single.    It helps them save money and get ahead.

The labs treat their employees well.  If they don't, they can't produce a good product.    Producing a marketable product is what any business must do.
