The record base for a multiple, implant‐supported, fixed prosthesis may be attached to the implants by screws. The screw attachment provides a stable record base for recording maxillo‐mandibular relationships. Extraoral adjustment of the occlusion rim requires that it be unscrewed to allow removal from the mouth. The rim must be reattached with screws for the next intraoral evaluation. Although this cycle of removal and replacement provides stability, retention, and accuracy, it is time‐consuming and inefficient. To resolve this problem, a two‐piece record base/occlusion rim can be used. The screw‐retained record base remains intraoral for the duration of the clinical appointment. The occlusion rim is designed to fit over the record base, with retention and stability, without screw retention. Use of the two‐piece record base/occlusion rim facilitates convenient removal, adjustment, and replacement of the occlusion rim.
