How to solve the problem of intraoral scanning of edentulous arches.
Introduction
Theintraoral scanning of edentulous areasis often considered a complex and, in many cases, a failing procedure.
However, in most situations, the problem is not related to technology, but to the clinical conditions under which the scanning is performed.
👉 To understand the fundamental principles of intraoral scanning of edentulous areas, refer to theguide on intraoral scanning of edentulous arches: feasibility and accuracy
Why is scanning edentulous areas more difficult?
Edentulous arches have characteristics that make scanning more complex:
absence of reference dental elements
presence of mobile soft tissues
limited access to the scanning field
the acquisition paths and scanning strategies are crucialpercorsi di acquisizione e le strategie di scansione
The main reasons why scanning fails
1. Instability of soft tissues
Continuous movement of the tissues is the main cause of failure.
👉 This is one of themost critical aspects in stabilizing tissues during intraoral scanning
2. Loss of tracking
Intraoral scanners require surfaces that are stable even with less pronounced textures.
In their absence:
the system loses tracking
cumulative errors occur
artifacts are generated

3. Insufficient access
A scanning field that is not fully accessible leads to:
incomplete acquisition
loss of precision
generating distortions
4. Incorrect workflow
An incorrect sequence compromises the final result.
👉 Follow thestep-by-step intraoral scanning workflow
5. Incorrect expectations about technology
Many failures stem from the idea that the scanner can compensate for non-optimal clinical conditions.

How to avoid scanning failure
To achieve predictable results, it is necessary to:
stabilize the tissues
improve access and visibility
follow a correct workflow
use appropriate scanning strategies

The real point: control of clinical conditions
Intraoral scanning of edentulous patients does not fail due to technological limits, but due to:
lack of field control
tissue instability
suboptimal operating conditions
Conclusions
Theintraoral scanning of edentulous areascan be highly predictable if performed under the correct conditions.
👉 Success depends on theability to control access, stability, and workflow.
