To my thinking, the harder the tooth....ei abrasion resistance the harder it is on the bone. I have seen long term cases where the bone is flat flat flat because of porcelain teeth. So it is not just about wear factor....Insurance companies will often replace dentures greater than five years old and plastic teeth are far less damaging on the tissues...So it is a long term affect we need to care about for patients....For my practice I usually prescribe a soft liner on the lower to help stave off the damage done by hard teeth....People like the notion of having teeth last a long time but at the cost of bone??? We cannot just simply provide them with the latest and most abrasive resistant teeth...Your thoughts?
