"Actually", you are wrong. There is a specific sales support team within Zimmer Dental -Regenerative Sales Specialists, or Support, or something to that effect and carry the dental bone and tissue regen products - I know the guy in my area. The group you are referring to is the biologics/sports team that Recon gobbled up although they have always worked to support the recon/trauma sales reps in their area. There's a handful of them in the country. They have the 3 catilage and visco products you mentioned. They are like our Knee PSDs but called something else - Regional Biologics Specialist? Biologics Sales Specialist? something like that.
Not arguing. Just clarifying. Seemed to me the OP was probably asking about a "Regenerative" position they may have heard someone talking about. It's more likely that "regen" was probably used to describe the dental business, not the regional sports specialists.
