Evaluation of Effect of Immediate Loading on Clinical Success after Immediate Implantation: A Systematic Review and Meta-Analysis

The aim of this systematic review was to evaluate the effect of immediate loading on clinical success after immediate implantation In this study, Pubmed, ISI (Web of Science) and Scopus databases were searched according to selected keywords all the articles indexed by October 22, 2013 which were in english were evaluated. Full text of the articles meeting the primary criteria to be included in this research, were obtained and appraised using the Oxford score sheet. Data of studies were extracted if they were scored as high or moderate level of evidence. Due to variation of methods of studies, they were divided into three categories and then metaanalysis was performed. 1270 articles were collected after searching the databases and finally 132 full texts were studied for data gathering. After methodological assessment and determination of level of evidence, 21studies were selected for metaanalysis. The results of the this study revealed that regarding the success rate, although there was no significant difference between immediate and delayed implantation, immediate implantation showed lower incidence of bone loss in single implants Immediate implantation and immediate loading, providing the existence of its prerequisites, are effective treatment methods in reducing the time of treatment and preserving crestal bone around the implants.
