Since Brånemark first started developing its implant system, there has been a continuous and significant evolution in oral implantology through experimental and clinical research, and many of the concepts that were once considered valid have now become the subject of debate. The insertion of the implant immediately after extraction of the tooth to be substituted has now become the implant treatment of choice and is associated with preserving the bone structure and the gingival architecture, as well as with reducing the treatment time, which ultimately benefits the patient.

Objective:

To evaluate the success rate of the immediate post-extraction implants (IPI) subject to immediate loading. Study

Design:

A meta-analytic study was carried out on 659 immediate post-extraction implants obtained from abibliographic review of 25 articles published within the last 9 years.

Results:

We obtained a sample of 322 patients who had been treated with a total of 659 implants placed immediately following extraction. The mean age of the patients was 51 years old. A total of 441 implants were inserted in the maxilla, 152 in the mandible and 64 were placed in an unspecified location. The survival rate ranged between 85% and 100%.

Conclusions:

Immediate post-extraction implant treatment is an implant alternative with a survival rate similarto that of the conventional technique for implant placement and enables preserving both the bone structure and gingival architecture, as well as providing immediate functional loading, thus improving the quality of the treatmentas far as the patient is concerned (AU)
