Summary
Digital models from intraoral scanners offer comparable accuracy to traditional plaster models for pediatric dental space analysis. This digital approach also significantly reduces differences between examiners, improving consistency in pediatric dentistry.
Area of Science:
- Dentistry
- Orthodontics
- Digital Imaging
Background:
- Mixed dentition space analysis is crucial in pediatric dentistry.
- Clinical adoption of digital models from intraoral scanners remains limited.
- Conventional methods rely on plaster models.
Purpose of the Study:
- To compare the accuracy of digital versus plaster models for mixed dentition space analysis.
- To evaluate inter-examiner variability between the two model types.
Main Methods:
- A preliminary study with a small sample size and one reference model.
- Calculated space for mandibular permanent teeth and arch length discrepancy.
- Utilized both digital models (optical impression) and conventional plaster models.
Main Results:
- Digital and plaster models showed comparable accuracy for space analysis.
- The largest difference in arch length discrepancy was clinically insignificant (-0.49 mm).
- Digital models yielded significantly fewer inter-examiner differences compared to plaster models.
Conclusions:
- Digital model space analysis demonstrates comparable accuracy to conventional plaster models.
- Digital models likely reduce inter-examiner variability in pediatric dental analysis.
- Intraoral scanner-based digital models show promise for clinical application.
