Immediate loading of mandibular implants in compromised patients: preliminary results.

To minimize the number of implant surgical procedures, a total of 72 single-stage, transgingival Frialoc implants (Friadent) were placed in the mandibles of 18 patients who required implant restoration. The patients' ability to undergo surgical implant treatment was restricted because of either poor general medical health or psychologic conditions. All implants were immediately loaded with a bar-retained overdenture.
