Brief Summary

Calculation of Mesiodistal width of maxillary and mandibular anterior teeth :

1. 1.Scan the patient's maxillary and mandibular arches to obtain digital casts using an intraoral scanner.
2. 2.Upload the digital casts and occlusal record scans into the CAD-CAM software (Dental System; 3Shape).
3. 3.Measurement of mesiodistal width for maxillary and mandibular anterior teeth.

Conditions

Correlation of the of the Mandibular to theMaxillary

Keywords

Widths of the Mandibular to theMaxillary Anterior Teeth.; Widths of the Mandibular; mesio-distal width of Mandibular

Outcome Measures

Primary Outcomes (1)

• 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.

  Baseline
