Summary

This summary is machine-generated.

Dental impressions with fixed appliances are less accurate due to bracket undercuts. Covering brackets on the gingival side or removing the archwire may improve impression precision.

Area of Science:

Orthodontics
Dental Materials Science
Biomedical Engineering

Background:

Accurate dental impressions are crucial for effective orthodontic treatment.
Fixed appliance therapy introduces complexities that can affect impression accuracy.

Purpose of the Study:

To evaluate the accuracy of dental impressions and plaster models during fixed appliance treatment.
To identify factors influencing impression accuracy in the presence of orthodontic brackets and archwires.

Main Methods:

Maxillary typodonts with various bracket configurations were used.
Impressions were taken with different techniques, including wax application.
Virtual models were created and compared to scanned typodonts for dimensional analysis.

Main Results:

Teeth with brackets showed significantly higher mean differences compared to reference blocks (0.169 mm vs. 0.019 mm).
Incisors exhibited the largest deviations (0.258 mm).
Covering brackets on the gingival side with wax resulted in a smaller mean difference (0.152 mm).

Conclusions:

Bracket undercuts inherently reduce dental impression accuracy.
Removing the archwire or selectively covering brackets may enhance impression precision.
Clinicians must account for potential inaccuracies when taking impressions during fixed appliance treatment.
