A meta-analysis on prospective clinical trials yielded thirteen studies with 1,955 dental implants, of which 914 were short implants < 10 mm in length.
Short implants had an estimated survival rate of 88.1% at 168 months, compared to a similar survival rate of 86.7% for standard implants (P=0.254). The peak failure rate for short dental implants occurred between 4 and 6 years of function. The peak failure rate for standard implants occurred between 6 and 8 years of function.
Similar long term survival rates for implants < 10 mm in length compared to longer implants. When implant failure did occur, it was at an earlier stage for the shorter implants.
Dr. Gebrael’s Comments:
Bone augmentation procedures have limitations and may not be acceptable to many patients due to increases in cost, treatment duration, and site morbidity. Short implants can be used with a good long term survival rate. This meta-analysis however was not able to determine the influence of bone density or type of prosthetic reconstruction on implant survival.
