Review of scientific literature on immediate loading concept of dental implants and its clinical procedural methods

Today immediate loading (IL) of dental implants is an eminent and acknowledged treatment strategy which is extensively being used for the rehabilitation of missing teeth in healthy as well as medically compromised individuals. IL may be described as functional loading (with occlusal contacts) immediately after implantation (or within 3–4 days after surgery) without waiting for the healing period. IL has gained popularity due to less tissue trauma, reduced overall treatment time, decreased patient’s anxiety and discomfort, high patient acceptance and better function and aesthetics. A fundamental prerequisite for implant success is substantial primary stability at the time of insertion and following loading of the implant. Hence, in the present literature review, we aimed to assess and clarify the significance of immediate loading and its various modes surfaced over the years comprising All-on-Four Concept, Weld One Concept, Basal Implants and Zygomatic Implants.
