Summary
This case study highlights a 9-year success of digital workflows, including face scans and CAD/CAM, for full-mouth rehabilitation with increased vertical dimension of occlusion (VDO) using lithium disilicate restorations.
Area of Science:
- Digital dentistry
- Restorative dentistry
- Prosthodontics
Background:
- Severe tooth wear necessitates complex full-mouth rehabilitation.
- Increasing the vertical dimension of occlusion (VDO) is a common challenge in restorative cases.
- Digital workflows offer potential for improved predictability and efficiency.
Purpose of the Study:
- To describe a digital workflow using face scans and CAD/CAM for full-mouth rehabilitation with increased VDO.
- To evaluate the long-term clinical outcome of adhesive lithium disilicate restorations in such cases.
Main Methods:
- A 46-year-old patient with severe tooth wear underwent full-mouth rehabilitation.
- Digital face scans and intraoral data were integrated for virtual planning.
- Minimally invasive preparations guided by digital planning.
- Long-term provisional restorations tested the new VDO.
- Final restorations fabricated from lithium disilicate.
Main Results:
- A digital workflow utilizing face scans and CAD/CAM technology was successfully implemented.
- The treatment involved full-mouth rehabilitation with increased VDO using adhesive lithium disilicate restorations.
- No failures were observed during the 9-year follow-up period.
Conclusions:
- Digital workflows enhance virtual visualization and quality control in dental wear cases.
- This approach offers significant time savings and increased predictability for clinicians and technicians.
- The described digital workflow provides a reliable treatment concept for full-arch rehabilitation with increased VDO in patients with dental wear.

Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...

Automated diagnostic analyzers have transformed clinical microbiology by providing rapid and reliable methods for pathogen identification and antibiotic susceptibility testing. Among these systems, the Vitek 2 is widely used because it automates the traditionally labor-intensive processes of microbial identification (ID) and antibiotic susceptibility testing (AST), delivering standardized and timely results that are essential for effective patient care.Microbial Identification with ID CardsThe...
