Simon Hadlington previews the novel materials coming soon to a dental surgery near you
In Short:
Developing materials that can cope with the hostile environment of the mouth is challenging
Resin composites are replacing amalgam for teeth restorations, but they can be difficult to stick in place
Growth factors, that promote bone growth, are being attached to surfaces of Ti implants to allow them to be fixed to damaged jaw bones
High-tech adhesive materials that encourage growth of new bone are being developed for more severe cases of jawbone damage
Teeth have a hard time of things. Not only are they required to crunch, break, chew and tear, they also exist in a remarkably hostile and extremely variable environment. So when it comes to mending damaged or diseased teeth and bones in the mouth, the challenge to develop materials that can cope with these stresses are nothing if not substantial. Furthermore, there is an increasing demand from patients that materials are aesthetically pleasing - ugly metallic fillings are gradually becoming a thing of the past. The chemistry behind fixing teeth and bones in the mouth, and developing new ways to prevent damage is, literally, science at the sharp end.
