About

The goal of this controlled clinical trial is to compare the effects of two distalization methods supported by inter-radicular mini-screw for maxillary molars distalization in 20 adult patients with skeletal class I or moderate skeletal class II malocclusion, dental class II molar relationship, and full permanent dentition. The participants were randomly selected according to inclusion / exclusion criteria from the outpatient clinic of the Department of Orthodontics and Dentofacial Orthopedics, Faculty of dentistry, Ain Shams University, Cairo, Egypt. Selectees age was ranging from 18 to 25 years old.

An informed consent has been signed by each patient before his / her enrollment in this study, where the aim , methodology, and possible complications were been clearly described in details. This research has been thoroughly reviewed by the Research Ethics Committee of the Faculty of dentistry, Ain Shams University.

Full description

This study is a two-arm, parallel group, prospective randomized clinical trial with the allocation ratio of 1:1. The Consolidated Standards of Reporting Trials (CONSORT statement) were used as a guide for this study.

After reviewing the study protocol, the ethical committee at the Faculty of Dentistry, Ain-Shams University approved the study.

Before treatment was carried out, a detailed written Arabic consent was signed by all the subjects of both groups after full explanation of the aim of the study and the procedures.

This prospective clinical study was conducted on a total of 24 maxillary first molars.

No financial competing interests: This study was part of a Masters' degree in Orthodontics, Faculty of Dentistry, Ain-Shams University.

No financial conflicts of interest were declared. The study was self- funded by the principal investigator.

A sample size of 24 distalizing sites was selected and divided into two groups twelve each:

Group 1: Single coil spring. Group 2: Double coil spring.

Enrollment: 24 patients

Sex: All

Ages: 18 to 25 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

3. Full permanent dentition with exclusion of third molars.
4. Both first and second maxillary molars are in occlusion.
5. Skeletal class I, mild or moderate skeletal class II malocclusion.
6. Full cusp or end to end class II molar relationship.
7. Mild to moderate crowding in the upper dental arch and / or increased overjet.
8. Normal or horizontal growth pattern.
9. Non-extraction treatment plan.

Exclusion criteria

1. Previous orthodontic treatment.
2. Treatment planning requiring orthognathic surgery.
3. Severe molar rotation.
4. Poor oral hygiene.

---

24 participants in 2 patient groups

Group 1: Single coil spring

Experimental group

Description:

A single open coil spring was inserted between the maxillary second premolar and the maxillary first molar with a distalizing force 300 gm.

Treatment:

Device: Maxillary molars distalization

Group 2: Double coil spring

Experimental group

Description:

Two open coil springs were inserted. The first coil spring was inserted between the maxillary second premolar and the maxillary first molar with a distalization force 300gm, and the second coil spring was inserted between the maxillary first and maxillary second molar with a distalization force 200 gm.

Treatment:

Device: Maxillary molars distalization
