Background & Aim: The absolute advantages of immediate loading of dental implants, such as time saving, immediate function and patient satisfaction, increases the demand for this protocol. In this article we report the results of literature review on conditions under which necessary for successful immediate loading and discuss the predictable conditions as well.
Materials & Methods: Search of relevant published articles was conducted for the period between 1970 to 2007 in Medline, PubMed, Embase, Blackwell Synergy, Sciencedirect, Scholar google, Google and Yahoo databases along with manual search to identify pertinent English text-books. The key words used for this search were dental implants, immediate loading, early loading, delayed loading, occlusal loading and primary stability. Factors that may influence the success of immediate implant loading, including patient selection, type of bone quality, required implant length, micro- and macrostructure of the implant, surgical skills, the need for achieving primary stability/control of occlusal forces, and prosthesis guidelines, were thoroughly reviewed and discussed.
Results: Immediate loading is predictable in the anterior section of the mandible, irrespective of implant type and surface topography (success rate 90% - 100%). Limited evidence is available for edentulous maxilla and partially edentulous patients. Unfortunately most of the reviewed articles provided limited information due to study design and methodological shortcomings.
Conclusion: Anatomical locations implant designs, and restricted prosthetic guidelines are a key to ensure successful outcomes. Future studies, preferably should be more of randomized control trials and prospective longitudinal studies are certainly needed before this approach can be widely used.
Key words: Dental Implants - Immediate Loading - Early Loading - Delayed Loading - Occlusal Loading - Primary Stability.
