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.
To evaluate the success rate of the immediate post-extraction implants (IPI) subject to immediate loading.
A meta-analytic study was carried out on 659 immediate post-extraction implants obtained from a bibliographic review of 25 articles published within the last 9 years.
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%.
Immediate post-extraction implant treatment is an implant alternative with a survival rate similar to 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 treatment as far as the patient is concerned.
评估即刻种植即刻负载（IPI）的成功率。
对过去 9 年中发表的 25 篇文献进行文献回顾，对 659 个即刻拔出种植体进行了荟萃分析研究。
我们获得了 322 名患者的样本，这些患者共接受了 659 个种植体的治疗，这些种植体是在拔牙后即刻植入的。患者的平均年龄为 51 岁。共有 441 个种植体植入上颌，152 个种植体植入下颌，64 个种植体植入未指定位置。存活率在 85%至 100%之间。
即刻拔出种植体治疗是一种种植体替代方案，其存活率与传统种植体放置技术相似，既能保留骨结构和牙龈结构，又能提供即刻功能性负载，从而提高治疗质量，使患者受益。
