I have been restoring implants for 6 years. I had never placed one because of the complexity of the anatomy and the armamentarium. However, I have now taken courses for mini implants and have placed them in sawdust mandibles. This is quite a bit simpler, than conventional implants, and requires far less equipment. I am thinking of restricting my use to the anterior mandible for supporting overdentures. I am concerned about longevity. For those of you actually doing this, what are your expectations for longevity? What, if any, complications have you experienced in placing these implants?
