A systematic review on the immediate loading and single dental implants: major clinical considerations

Introduction: the immediate loading implant (ILI) is considered to offer many advantages for the patient and the clinician, maintaining the height of the soft tissues and increasing the peri-implant bone density. Also, ILI is associated with reductions in patient pain, time, and material, with success rates of 95 to 100% being reported. Objective: Therefore, the objective of the present systematic review study was to analyze the clinical success of the immediate loading technique, to present the indication criteria and the follow-up of the procedures. Methods: The rules of the Systematic Review-PRISMA Platform. The research was carried out in July 2019 to August 2021, with articles published in the last ten years, and developed based on Scopus, PubMed, Science Direct, Scielo, and Google Scholar. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 114 articles were found involving the Immediate loading and single dental implants. A total of 94 articles were evaluated in full and 35 were included and evaluated in the present study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 30 studies with a high risk of bias, and 29 studies that did not meet the GRADE. The present systematic review study showed that the success rates with the ILI technique are compatible with those of the late load, as long as certain guidelines are followed that were divided into factors related to the patient, the surgical technique, the implant, the prosthesis, and to aesthetics. The high success rate is a consequence of the correct surgical and prosthetic planning, harmony between the implant system, patient, and dental surgeon. As for the region, currently, it can be said that ILI in total jaw rehabilitation is a procedure with high success rates that should and can be applied in all cases where the technique is efficient to provide adequate primary stability to the implants. Therefore, the technical improvement of the dentist becomes the main condition for this philosophy to be applied
