Scan-only denture techniques represent the most streamlined digital pathway for edentulous patients—no alginate, no custom trays, and no wax rims in the traditional sense. Success depends on rigorous scanning protocol and close coordination with your denture design lab. This article details the clinical steps and quality thresholds our team expects when processing scan-only cases through the workflow portal.
Why This Matters
- Improved patient experience without impression material gag reflex and discomfort
- Reduced appointment count by combining data capture steps into fewer visits
- Digital accuracy that eliminates impression distortion and pour errors
- Immediate digital archive for future copy denture or repair fabrication
When You'll Use This
This technique applies best to edentulous patients with adequate ridge form and manageable soft tissue mobility, where a well-executed intraoral scan can fully replace a final impression.
- Edentulous patients who cannot tolerate conventional impression procedures
- Efficient denture replacement cases with reference denture scan protocols
- Group practice settings standardizing on digital-only edentulous workflows
- Immediate denture cases using pre-extraction dentate scans converted post-extraction
Step-by-Step Process
Removing the physical impression step doesn't remove the need for the information it used to capture—this sequence shows where that information now needs to come from instead.
- Prepare the edentulous ridge with tissue manipulation and peripheral border molding digitally
- Scan upper and lower ridges following manufacturer edentulous scan strategy
- Capture jaw relation using scan bite rim, reference denture scan, or photogrammetric aids
- Submit scans with prescription detailing tooth mould, shade, and occlusal preferences
- Review and approve virtual design before try-in fabrication and final processing
Best Practices
- Follow scanner-specific edentulous scanning sequences for optimal tissue capture
- Use a reference denture scan when replacing an existing prosthesis with acceptable jaw relation
- Verify scan completeness by reviewing the 3D model for holes or missing peripheral data
- Communicate tissue compressibility expectations so the lab designs appropriate base relief
Common Mistakes to Avoid
- Scanning without tissue manipulation, producing shallow peripheral borders
- Using dentate scanning strategy on edentulous ridges, resulting in incomplete capture
- Omitting jaw relation data and expecting the lab to estimate occlusal vertical dimension
- Submitting low-resolution scans with visible stitching errors or surface artifacts
“Going scan-only doesn't lower the bar for record quality—it just moves where that quality has to be captured.”
Conclusion
Strong outcomes in scan-only denture technique: eliminating physical impressions depend on clear clinical goals, accurate records, and a planning partner who understands manufacturing requirements.
