Research Abstract

In the group where received socket preservation therapy with autogenous bone, the newly formed bone around the implants showed the property that was similar to the bone around the implants which did placed to normal extraction socket. In the group where received socket preservation therapy with β-TCP, the area of newly formed bone that directly contacted the implant surface was smaller in the other groups.
