Objectives
Intraoral scanners have become essential tools in dental practice, and achieving accurate results can positively impact treatment approaches. Nevertheless, varied factors, such as illuminance, may affect scanning accuracy. From that point of view, this clinical study aims to evaluate the impact of the clinic light's illuminance on the occlusal morphology digitalization ability.
Materials and Methods
Four groups were created based on clinical illuminance conditions: Clinical Lightness (CL) ~1000 Lux and Clinical Darkness (CD) ~0-15 Lux, and maxillary and mandibular arches. Ten digital scans (TRIOS4; 3Shape) were performed for the maxillary and ten scans for the mandibular jaw of a patient with ambient light settings. A master digitalization was performed according to The European Standard for Illumination (EN 12464) ~10.000 Lux. The 3D deviations between the reference data and digital scans were calculated and depicted on color-difference maps (Geomagic Studio 2015; 3D systems). A one-way ANOVA and Tukey test was used (a=.05).
Results
Significant differences in accuracy values were found among the maxillary and mandibular arches within the same clinical illuminance conditions(p<.001).
Conclusions
The results of this study, despite its limitations, highlight the significant differences in digitalization values between the mandibular and maxillary arches under the same illuminance conditions.
