Using Dental Wax as Filler One of the jobs that I wholeheartedly dislike is filling gaps. It vividly reminds me of the monstrous resin tooth we had to make quite early in dental school, a tooth 9 cm long and 3 wide and deep, and I can tell you, that meant lots of sanding. As long as the filler is not required to improve the model's structural stability and it need not be applied over wide areas, dental casting wax is a very suitable and time-saving alternative. Nowadays, most filling means closing comparatively small gaps, most often at the wing roots of aircraft models, and this is where wax is the winning alternative. Excessive filling done with dental wax is evident on the belly of Gromit's figure .
Dental technicians use a number of different waxes for various purposes.
For plastic models, we need a wax that has a comparatively high melting point and is rather hard, so that it can be scraped to a certain form. These demands are met by casting and aesthetic dental waxes, normally used to produce models of inlays, crowns and bridges that are used as masters for casting in metal. The required narrow range of tolerance in this process ensures that dental waxes used are of high quality. You can buy them in smaller or bigger sticks as well as in various colors, including red, green, yellow and blue. I use Schuler's sthetikwachs , which is ivory colored.
