Brief summary

A crossover study will be conducted on 20 pediatric patients aged 7-11 years. For each participant, the upper and lower study models will be processed using two methods: the conventional method, which involves alginate impressions, and the digital method, which utilizes a 3D intraoral digital scanner (CEREC Omnicam scanner or equivalent). Measurements of arch length, arch width, and arch depth will be taken from both model types using the conventional method with a brass wire and a digital caliper. At the same time, in the scan cast, they will be calculated digitally by 3D shape software. Statistical analysis will be done to compare the results of both methods.

Design outcomes

Primary

Measure	Time frame	Description
Subjective outcome	2 months	Patient acceptance will be recorded according to Modified Facial scale modified from the Maunuksela et al scale showing the 3 schematic faces representing: (A) satisfaction; (B) indifference; and (C) dissatisfaction, respectively.
Objective Outcome (Measurement)	2 months	arch width (inter canine and intermolar width) measured in mm
Patient acceptance	2 months	Frankl's behavior rating scale will be re-evaluated after each method used. Score 1-4. score 1=definitely positive, score 2=positive,score 3=negative,score 4=definitely negative.
