Abstract

The purpose of this study was to determine whether clinical success can be achieved with Brånemark system short implants (Nobel Biocare) three years after the placement of implants. <br/> One hundred and thirteen short implants (＜10 mm) were installed:42 implants with smooth surfaces and 71 implants with rough surfaces. Twenty-two implants were installed in the maxilla, and 91 implants in the mandible. All implants were submerged. A chi-square test was used to evaluate the significance of implant loss of short implants with implants longer than 10 mm.<br/> There was no significant difference in the failure rates between short implants and implants longer than 10 mm. Among smooth surface implants, the failure rate of short implants was significantly higher than that of implants longer than 10 mm, but among rough surface implants, no significant difference in the failure rates was observed between short implants and implants longer than 10 mm. These results demonstrated that short implants with rough surfaces were as useful as implants longer than 10 mm.
