The invention provides an implant support, a mixing vessel and an implant support assembly. The implant support assembly includes a first housing, a second housing, a mixing vessel for receiving powder, and a sealed container. The first housing and the second housing are openly assembled together to form a receiving space. An implant is contained in the receiving space. The second housing has a hole which is in communication with the receiving space. The mixing vessel is used for accommodating powder and the sealed container contains liquid. The sealed container is installed into the mixing vessel and the mixing vessel is installed in the second housing to allow the sealed container to face the hole. During the assembly process of the mixing vessel to the second housing, the second housing allows the sealed container to get close to the mixing vessel and allows the sealed container to get broken so as to allow liquid to flow into the mixing vessel from the sealed container to be mixed with the powder, and be injected into the receiving space via the hole to be attached to the surface of the plant. According to the invention, through the assembly structure between the mixing vessel and the implant support assembly, the powder and the liquid can be mixed in the mixing vessel and then injected to the space where the implant is located.
