A digital technique for transferring the maxillomandibular relationship using photogrammetry, an intraoral scanner, and a computer-aided design software program is described in a treatment involving immediate loading in a patient with mandibular edentulism. The edentulous mandible was located preoperatively in a centric occlusal relationship with a denture, and preoperative and postoperative cone beam computed tomography (CBCT) data were aligned and merged based on bone markers. This technique, which allows the transfer of the presurgical maxillomandibular relationship during the immediate loading procedure, is more objective, more straightforward, and faster than the conventional method.

Figure 1 shows the workflow for transferring the presurgical maxillomandibular relationship for immediate loading in a mandibular edentulous patient, which is described as follows:

Guide the patient’s mandible into centric relation by using the bimanual manipulation technique12 and record the jaw relationship using a silicone material (O-Bite; DMG Chemisch-Pharmazeutische Fabrik GmbH). Then, perform a CBCT scan (3D eXam; KaVo Dental GmbH) and export to a DICOM format file (DICOM-1). Scan the

The purpose of this paper was to introduce a digital technique for transferring the maxillomandibular relationship during immediate loading for a complete mandibular edentulous patient. The technique is effective for obtaining a digital workflow to streamline edentulous implant-prosthodontic procedures.

Transfer of the maxillomandibular relationship in a digital workflow is accomplished via alignment of the data from 2 CBCT scans made preoperatively and postoperatively using stable bone markers
