The Distal Extension Case: An Alternative Restorative Design for Implant Prosthetics

A restorative design is introduced in preference to the implant-supported bar, clip, or ball-type removable prosthesis. It has been necessary to develop an alternative treatment approach to the placement and restoration of implants in the posterior mandible or maxilla. In an examination of the available therapeutic choices and their rationales, this treatment option offers greater function, esthetics, and comfort. Four maxillary and one mandibular arches were reconstructed with anterior implant-supported fixed bridges/splinted restorations and a precision partial denture design posteriorly, using an extracoronal universal ball attachment. These cases have demonstrated minimal maintenance up to 7 years in function.
