In saving nearly extinct species, are we dooming them to generations of genetic disorders due to inbreeding?

Cheetahs survived a severe population bottleneck, likely around the last iceage, and there is very little genetic diversity between individuals or populations.

Inbreeding can be a method for removing the genes that cause genetic disorders from a population.   


oversimplified: The same math that causes negative receives to express in inbreeding also causes offspring that have none of the recessive. The offspring of those without the negative gene will never have it with or without inbreeding. The ones that have the double negative die. The offspring that are mixed will repeat the process and have fewer viable offspring than the recessive free. Ultimately the recessive becomes rare.  


Inbreeding in domestic animals like dogs only causes problems because of artificial selection. Human intervention of only breeding dalmatians with a particular color pattern prevents kidney disease from being the selective pressure that it would be in the wild and as a result ends up becoming more common.
