Full-mouth rehabilitation of worn dentition using a simplified digital workflow with superimposition of scans for recording and transferring new vertical dimensions

Rehabilitating a severely worn dentition presents significant clinical challenges in relation to establishing a vertical dimension, recording and transferring the planned vertical dimension, particularly when combining tooth and implant-supported restorations. This case report demonstrates a two-stage full-mouth rehabilitation approach using a digital workflow to simplify complex procedures and enhance predictability. A 58-year-old male patient with generalized severe attrition and a collapsed vertical dimension of occlusion (VDO) underwent minimally invasive restoration with ultra-thin porcelain laminate veneers (PLV) and onlays. The treatment involved increasing the VDO and using a novel superimposition of scan (SOS) technique to digitally record and transfer the new occlusal relationship after dual-arch tooth preparations. In the first stage, tooth-supported restorations were completed to establish the new VDO, followed by an implant-supported prosthetic rehabilitation in the second stage. This phased digital protocol minimized chairside adjustments and eliminated the need for conventional bite registration, ensuring occlusal harmony. The technique offers general practitioners a simplified, systematic workflow for complex full-mouth rehabilitations, emphasizing minimally invasive principles and contemporary adhesive materials.
