Does Blender offer software for creating dental models? I am in need of designing and creating these models for 3D printing. The big corporations that offer this service are inaccurate.
Blender is a 3D creation suite. It does not 'offer' any software, because it is a piece of software itself. Although not primarily intended for dental models, it should offer all necessary tools to create them.
However judging by your complaints about the inaccuracy of professional services, I guess you are trying to scan something rather than modeling it yourself? This can definitely not be achieved with vanilla Blender.
One general thing on a side note: If 'big corporations' are not capable of fulfilling a task to your satisfaction, you might be asking something, that is out of today's technical scope...
