Abstract

Abstract:

When the height of available bone in the implant site is insufficient due to the limitation of anatomical factors, the use of short dental implants (length ≤6 mm) gradually becomes a potential treatment choice. The application of short implants expands the indications of dental implants and simplifies the surgery procedure, which can also reduce the cost and shorten the treating time. Although short implants have the advantages mentioned above, the actual success rate in clinical application is still lower than that of conventional implants, which limits their clinical application. Therefore, to investigate the selection of reasonable indications and analyze the factors which affect the success rate of short implants are of great significance for dentists to make decision and improve the success rate of short dental implants. Through a systematic review of the literature, this article discussed the definition and indications of short implants, and analyzed the effects of diameter, geometric design, surface characteristics, crown/implant ratio and other factors on the success rate of short implants. It is helpful for dentists to comprehensively understand short dental implants and make a reasonable selection in clinical application.

Key words: Short Dental implants, Success rate, Surface characteristics, Geometric design, Diameter, Crown/implant ratio
