Summary
Planned Invisalign® expansion is not predictable. This study found significant differences between planned and actual expansion in patients, indicating limitations in treatment predictability with the ClinCheck® system.
Area of Science:
- Orthodontics
- Biomaterials Science
- Dental Technology
Background:
- The Invisalign® system utilizes digital treatment planning via ClinCheck® software.
- Quantifying the predictability of orthodontic expansion is crucial for effective treatment outcomes.
Purpose of the Study:
- To validate a novel method for measuring Invisalign® expansion predictability.
- To compare planned expansion in ClinCheck® with actual clinical outcomes using 3D models.
Main Methods:
- 116 patients undergoing Invisalign® expansion were studied.
- Measurements of arch dimensions and tooth positions were taken from 3D models and ClinCheck® at T1 and T2.
- Statistical analysis compared planned versus actual expansion outcomes.
Main Results:
- High precision was observed in all measurements.
- No significant differences were found between 3D models and ClinCheck® at T1, except for molar cuspid width and arch depth.
- Significant discrepancies between 3D models and ClinCheck® were noted at T2 for multiple arch dimension and tooth position variables.
Conclusions:
- Planned expansion with Invisalign® at the end of treatment is not accurately predictable.
- This study highlights discrepancies between digital planning and clinical results in Invisalign® treatments.
- Findings suggest limitations in the predictability of expansion movements with the Invisalign® system.
