An offshoot of the Denta-Bots program, which itself was an offshoot of the old ToothBot program. RoboBraces are orthodontic devices designed to straighten teeth into an optimal pattern for the ingestion and mastication of food.
Previous orthodontic methods were highly inefficient, requiring months or even years of minute adjustment, the adjusting material to be discarded after use.
RoboBraces, on the other hand, could take as little as a few hour-cycles by using a series of manipulators, cutters, and a mixture of various chemicals that would not only serve as anaesthetic but could expand and harden almost instantly. Couple this with the the proper Whitener_Compounds and a special form authorizing use of such, and a clone's teeth would soon become the perfect shape and position for their job.
After the procedure completed, the RoboBrace would report back to its station until its next assignment.
Perhaps most surprising is they worked. Perfectly. Clones everywhere got better teeth in just a few hour-cycles, with hardly any pain and at a minimal use of resources or down-time. An unqualified success. Why, they could even eat VatSlime without difficulty.
At least, until the Defective_Batch_ACA675T09-XXXX got into them. That, in combination with Legacy_software, meant that pain management became secondary, and spreading proper mastication and chewing techniques primary. Once that had happened, they were able to use those same implements that had before so helped clones to cause them severe pain in the furtherance of their ends. So as we can see, it's really not their fault. The little things just couldn't help themselves.
Have we tracked down all of the defective models yet? They were used by clones of all clearances, and I'd hate to think that there might still be Asimov-substandard RoboBraces still in use by VIOLET_Supervisors, or worse, by fellow High Programmers.
Didn't Toothy-U mention something recently about orthodonture? I don't recall...
