The difference between an implant supported denture and an implant retained denture is the implant supported denture is only stabilized by implants, normally 2-4 in the front, to keep it from moving but the gums/soft tissue still support the denture. An implant-retained denture is completely retained by the implants and does not require gums and soft tissue to be supporting it. The implant-retained denture can also be made in 2 different ways, it is either so you can take it out like an implant-supported denture or it can be screwed in permanently like a bridge.
