Evaluation Of Different Rapid Orthodontic Expansion Devices

Phase 1

Completed

• Conditions: Cross Bite
• Interventions: Device: Rapid Expansion of palatal suture

• Registration Number: NCT03258411
• Lead Sponsor: King Abdulaziz University

Brief Summary

Evaluating and comparing the short term effects of different palatal expanders on the amount of palatal expansion and buccal tipping of posterior teeth.

Hypothesis:

H0: There is no difference in the short term effects between the different palatal expanders.

H1: There is a significant difference in the short term effects between the different palatal expanders.

Arm && Interventions

Group	Intervention	Description
Miniscrew-supported (MHx)	Rapid Expansion of palatal suture	Rapid Expansion of palatal suture device: bone anchored expander (Temporary anchorage devices(miniscrew)-supported (MHx))
Haas group (H)	Rapid Expansion of palatal suture	Rapid Expansion of palatal suture device: tooth-tissue supported expander (Haas (H)).
Hyrax (Hx)	Rapid Expansion of palatal suture	Rapid Expansion of palatal suture device: tooth anchored expander (Hyrax (Hx)).

Primary Outcome Measures

Name	Time	Method
Amount of skeletal and dental expansion	3 months	These are linear measurements which will be measured in millimetres in the first and the second cone beam computed tomography images and the difference will be calculated.
Amount of dental inclination	3 months	These are angular measurements which will be measured in degrees in the first and the second cone beam computed tomography images and the difference will be calculated.
