You are either Hans or an Osteohealth employee trying to place the blame elsewhere. All companies are misssing the point. A graft is an expensive proposition to a clinician. So you wanted me to buy Bio-Oss place a Bio-Gide membrane. Then you come at me with Gem and tell me mix it with TCP that you provided. Don't mix it with Bio-Oss off label use. I tried it did not work lesson learned. An expensive lesson since I had to re-graft and now it comes out of my pocket. Osteohealth made its money and is on the down side of the product cycle. There are superior products on the market. When you arived your competition was DFDBA, Osteograf N and P-15. Yes, Bio-Oss was the answer then but it is no longer the answer and GEM21 definitely is not the answer.
