SUMMARY: The lower the number, the more the material flexes before it breaks. At 10,000 MPa (or 10 GPa), Crystal Ultra is by far the most flexible dental ceramic in use today. This flexibility makes the material ideal for implant dentistry where sensation and cushion afforded by the peridontal ligament is lost, and it allows the material to stand up better to the test of time where chewing forces eventually cause all-ceramics to weaken, chip, and crack.
SCIENCE: Unlike other hybrids, a unique chemical bond is formed inside the Crystal Ultra material matrix which allows the polymers to flex while not breaking apart from the ceramics.
The photo to the right is a 3mm bar created out of Crystal Ultra and bent. No other ceramic material used in dentistry can bend like this without breaking.
Crystal Ultra is the only dental ceramic which is actually more flexible than both dentin and enamel while providing strength characteristics which are significantly superior to both.
