Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Scanning of the maxillary and mandibular dental arch will be performed for the same group of patients twice. The first time is before bracket positioning using two different scanners and the three different techniques. The second time is after brackets positioning using the same two different scanners and the same three different scanning techniques.
Then these scans will be compared to by superimposition techniques and linear measurement techniques.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Three different scanning techniques will be used: buccopalatal technique, S-shaped technique and palatobuccal technique. The buccopalatal technique (A) involves scanning the arch top side starting from the left second molar then run longitudinally to the contra-lateral one. Then go to the buccal side scan from this right side to the contra-lateral side and then palatal scan. Palatal scan done in two steps first was with counterclockwise movement along the palatal vault and then longitudinal movement in postro-anterior direction.
The S-shaped technique (B) involves scanning the arch starting from the palatal side of the left second molar then moving the scanner tip in alternating palatobuccal and buccopalatal S-shaped movement along the arch to the contra-lateral side. Then scanning the mid area of the palate by longitudinal movement in postro-anterior direction.
The palatobuccal technique (c) done by scanning the arch top side first starting from the left second molar runs longitudinally to the contralateral side. Then start palatal scanning by moving the scanner tip with circular movement in a clockwise direction across the palatal vault from the right-side second molar then along the palate to the contralateral second molar. Then the same circular scanning but in the counterclockwise direction to record the remaining part of the palate staring from the left second molar to the contralateral one. The buccal scan will follow starting from the right second molar then run longitudinally to the contralateral side.
