A comparative analysis evaluating how diastema and crowding affect 3D model precision, indicating critical implications for dental diagnosis and treatment.
Key Points
Evaluate how different levels of diastema and crowding affect the precision of 3D-printed dental models.
Modified digital models simulated varying diastema and crowding levels.
3D-printed models were scanned and digitally superimposed for precision analysis.
Statistical evaluations used one-way ANOVA and Tukey’s HSD.
5 mm diastema showed the widest range of deviation.
RMS and average deviations were highest in the 2.5 mm and 5 mm diastema conditions.
Significant deviations in crowding were observed only in the 12 mm group.
