The Brånemark Novum system is a new procedure for the one-day reconstruction of periodontally hopeless or edentulous mandibles. It consists of a series of four drill templates and eight drill guides to precisely position three implants that are completely level and parallel to one another. A prefabricated lower bar is attached to the implants. A prefabricated upper bar attaches precisely to the lower bar. The restorative clinician takes a bite registration at a previously established vertical dimension of occlusion. The case is waxed up and tried in the same day and delivered after processing. The procedure is described in detail, and 11 cases are reviewed.
