These terms are confusing because they are all marketing terms. None is scientific and none is defined. (Actually there is a definition of cohesive, but no one really follows it.) Manufacturers want to use terms that distinguish their products; surgeons want to promote themselves as doing something unique; and the FDA watches over to be sure that false claims are not made. During the cohesive trials which lasted over a decade, surgeons who did not have access to them became frustrated and started to claim that their products were cohesive (when they really were not.) Gummy bear is obviously not a scientific term and since it isn’t, then there are no strict criteria for what gummy bear really means.
