Whether immediate dental implants can be used as follows: 1. After immediate implantation, there is no denture on the implant, the root is buried in the bone to make a denture of other types to hang on the adjacent teeth, this situation can not be used immediately, only when the implant completes osseointegration can be used; 2. Immediate restoration without weight, the implant is particularly strong, the initial stability is better, and the patient is in great need of a If the patient needs a denture on the implant, a temporary denture can be made on the implant, but there is no occlusal contact and it cannot be stressed, it is only aesthetic, called immediate restoration without weight bearing; 3. Immediate weight bearing, only in very rare cases, when the implant is very stable and the extrusion force is very small, can the teeth on the implant and the opposing teeth make occlusal contact to be stressed. In most cases it is not recommended to put the implant under immediate stress, as this increases the risk of dental implant failure.
