Abstract
Introduction: The use of dental implants in the rehabilitation of partially or completely edentulous patients followed a protocol of submerging the implant for 3-6 months during osseointegration to reduce the risk of implant failure caused by movements at the interface. In this context, subsequent improvements in surgical techniques such as implant structure and masticatory forces have led to evidence that immediate loading procedures can be successful (immediately loaded dental implant -ILI). Objective: It was to demonstrate, through a systematic review, the main clinical approaches of immediate dental implants with other types of dental implants, presenting the indication criteria and follow-up of the procedures. Methods: The PRISMA Platform systematic review rules were followed. The search was carried out from October 2023 to January 2024 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. 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 133 articles were found, 45 articles were evaluated in full and 37 were included and developed in the present systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 25 studies with a high risk of bias and 23 studies that did not meet GRADE and AMSTAR-2. Most studies did not show homogeneity in their results, with X2=59.9%>50%. It was concluded that success rates with the ILI technique are compatible with those of delayed loading, as long as certain guidelines are followed, which were divided into factors related to the patient, surgical technique, implant, prosthesis, and aesthetics. The high success rate is a consequence of correct surgical and prosthetic planning, and harmony between the implant system, patient, and dental surgeon. Regarding the region, it can currently be said that ILI in total jaw rehabilitation is a procedure with high success rates that should and can be applied in all cases in which the technique is efficient in providing adequate primary stability to the implants. Furthermore, the immediate provisional restoration did not have a significant peri-implant impact on the soft and hard tissues surrounding the immediately placed single dental implants.
