It expects the dental and medical 3-D printing sector to grow by around 515 percent to $868 million by 2025, up from its current value of $141 million.
As a result, many printer manufacturers are designing machines and developing materials specifically aimed at the dental market, the group's report said.

"Applications are emerging in the medical and dental fields, where the opportunity afforded by cheap customisation is allowing surgeons to replicate a patient's body based on MRI and CT scans in order to practice difficult invasive procedures, and medical and dental implants which are fully customised to a particular individual can be generated," IDTechEx said.
With some 90,000 dental surgeries in the U.S. alone, the group estimates that dental-specific printer sales in the country could hit $180 million per year, as each printer costs around $20,000 and has an average lifespan of around 10 years.

Manufacturer Stratasys is named by IDTechEx as one of the leading companies in the space. Shares in the Nasdaq-listed group jumped as much as 19 percent earlier this month after it reported a 67 percent increase in second-quarter revenue, beating analysts' expectations.
In total, the 3-D printing market will be worth $4 billion by 2025, according to the report, as jewellery, aerospace and auto industries begin to implement the technology more.
