Immediate loading of narrow-diameter implants with overdentures in severely atrophic mandibles.

Oral rehabilitation using two to four implants to support mandibular overdentures has been shown to have success rates of approximately 96% with implants placed in a one- or two-stage procedure. The purpose of this study is to evaluate 10 consecutive cases of immediately loaded, narrow-diameter implants (NDIs) as support for overdentures in severely atrophic mandibles, and report on implant/prosthetic survival rates and patient satisfaction. Overall implant and prosthetic survival rates were 94.1% and 100%, respectively.
