Post-extraction dental implants are those that are placed in the same surgical act. First, the tooth is extracted and then the dental implant is placed. The small gap that remains after implant placement is filled with particulate bone to stimulate bone formation around the implant.

They were introduced in the 70s presenting a high implant survival rate, which is why it has now become a predictable alternative to traditional treatment.

The needs that have led to the introduction of this protocol are due to the demand of patients to reduce treatment time, but above all due to the need to preserve the alveolar structures that serve for the resorption process after tooth extraction.
Maintaining the original state of the bone and soft tissues around the tooth to be extracted is the key to obtaining optimal aesthetic results. Bone augmentation procedures are effective in promoting bone filling and resolution of the peri-implant defect in the extraction socket.

In maxillary premolars, the horizontal gap is greater than in the incisor-canine region, but the crest reduction is less. As long as there is good bone support, the initial stability of these implants is not very different from that achieved with delayed implants.
