NCT06308640

Brief Summary

The goal of this clinical trial is to to evaluate and compare the skeletal and dental changes of bone supported Fast Back and bone supported modified Leaf Spring Self-Activated Expander in bilateral distalization of maxillary molars using CBCT in Egyptian people. The main question it aims to answer are: • If bone supported Fast Back and bone supported modified Leaf Spring Self-Activated Expander will be effective in bilateral distalization of maxillary molars The patients will be selected according to the following criteria:

  1. 1.Patient with full permanent dentition.
  2. 2.Good oral hygiene.
  3. 3.None of the patients had received any orthodontic treatment.
  4. 4.Class II molar relationship.
  5. 5.Minimal or no crowding in the mandibular arch.
  6. 6.Non-extraction treatment plan with molar distalization.
  7. 7.Low angle cases.
  8. 8.No medical problems or active periodontal disease.

Study Arms (2)

Fast Back Rapid Distalizer

EXPERIMENTAL

Group 1: Consisted of 10 patients, their upper molar will be distalized with bone suppored Fast Back (Fast Back Rapid Distalizer, leone, s.p.a, Italy).

Device: Insertion of the device intraorally

Modified Leaf Spring Self-Activated Expander

EXPERIMENTAL

Group 2: Consisted of 10 patients, their upper molar will be distalized with bone supported modified Leaf Spring Self-Activated Expander. (Leaf Self Expander, leone, s.p.a, Italy).

Device: Insertion of the device intraorally

Interventions

* The distalizer appliance will be checked for adaptation intraorally, the two bands of the maxillary first molars will be fitted in their accurate position on the teeth. * The screw insertion will be carried out with the patient under local anesthesia. * They will be placed inside the two eyelets of the anterior arms of the screw in the appliance
