To be fair, if you are a manufacturer of dental equipment or supplies, you are forced to make a "Deal with the Devil" (one of these 4 main distributors) if you want to bother with a small market like Canada. They provide logistics, sales reps, service people, marketing, client base, and some guarantee of sales volume. If a manufacturer had to go it independently, it would be expensive.... So these 4 (KDental, Sinclair, Henry Schein, Patterson) make a deal with a manufacturer, for exclusivity, and provide all the resources needed to market, sell, service and provide sundries.
Speaking of sundries, the Hydrim uses some proprietary "detergent" which costs more than GOLD per ounce and can only be purchased from SciCan and it's small number of distributors. The stuff is probably not that hard a formulation to make, but there is no generic option or alternative. It would be good to figure out what the heck is in their detergent and sell an alternative/generic. Again, a tiny market.... probably worth $1-2 million a year? Maybe more? Who knows... but it can't be that hard filling up plastic bags and boxes with a liquid that probably costs a fraction to make of what these guys sell it for. Then you have to pay a fortune to market it, get people to buy it, etc.... Not to mention it probably needs HEALTH CANADA approval so by the time you are done paying everybody off, it is not worth the risk!
