What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Correlation of the Mesio-Distal WidthsOther
- Scan the patient's maxillary and mandibular arches to obtain digital casts using an intraoral scanner.
- Upload the digital casts and occlusal record scans into the CAD-CAM software (Dental System; 3Shape).
- Measurement of mesiodistal width for maxillary and mandibular anterior teeth.
What is being measured
The primary outcome is the main question the study is designed to answer.
Correlation between the mesiodistal widths of the mandibular and maxillary anterior teeth
The mesiodistal widths of the maxillary and mandibular anterior teeth will be measured on digital dental model using 3Shape CAD/CAM software after uploading the digital model and occlusal record scans. The correlation between the mandibular and maxillary anterior tooth widths will then be analyzed.
Measured: Baseline
