Ideal Material

I read in a site a few days ago, that there is still no "Ideal Material" in dentistry to be used (for filling) May I ask why? 😕 😕 Why scientists or even dentists didn’t discover an "Ideal Material”?

Also, I would like to ask does any one know a site which got good and almost all useful terminologies for dentistry or especially for dental material
Thanks 🙂​

Well I have a rudimentary knowledge right now but here is what I do know. First of all everyone wants a tooth colored filling no doubt. However current tooth colored fillings (direct restorations) are bonded chemically to the tooth structure after an acid etch to remove the smear layer so that enamel rods and dentin tubules are best ready to be bonded to. But upon curing there is shrinkage of the material around the margins so over time this speeds degradation along with normal occlusal force. An ideal material would never degrade or shrink upon curing.

As far as the site your after try dentaltown.com

Currently it seems that any time one ideal trait is perfected, other ideal traits are lacking.

If you're looking for an "ideal" material from the standpoint of a restorative dentist, you'd want(at minimum):

1) exact biocompatibility (i.e. wear rates/wear rates on opposing dentition and the same coefficient of expansion rates of enamel/dentin)

2) Ease of placement/handling (i.e. same performance in wet/dry conditions, non-technique sensitive steps, quick to place/finish)

3) Therapeutic effects to the tooth (i.e. if you're placing a restoration near the pulp, the risk of future pulpal pathology would be essentially eliminated)

4) Esthetic - both in basic color and degree of polishability

5) No polymerization shrinkage and a rapid curing time

There are probably about 10 other things you'd want also, but this little list can give you a good feel about why an "ideal" retsorative material curently doesn't exist
