This paper is to report our clinical analysis on short implants. Method and material: This study focuses on screw type implant system with fixtures 8mm or shorter. The implants are either anodized or HA-coated. The system allows the options of both one-stage and two-stage procedures. Covered in this follow-up study are 104 implants in 75 patients, composed of 22 males and 53 females between 40 and 83 years old, averaging 62.45 years old (male at 65.85 and female at 61.04). Those subjects underwent operations at 4 facilities belonging to Kyoto Institute of Implantology between 1992 and 2011. Result: Of 104 short implants 8 have been lost, with the survival rate of 92.3％. Maxillary implants survived at the rate of 89.6％ with 5 losses out of 48, and mandibular implants 96.4％ with 2 losses out of 56. Those were mostly placed in the posterior regions. Analysis: Given the context of our super-aging society, the role short implants can achieve seems to be significant, considering their advantage in terms of surgical and mechanical stresses effecting on the elderly.
