About

The goal of observational study is to learn about the stability of orthodontic treatment results in orthodontic patients during retention phase of treatment.

Full description

The aim of the present study was to three-dimensionally analyze tooth movement in retention phase of treatment and wherever double effectively retention prevents it.

Enrollment: 100 patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Non-extraction treatment
• No hypodontia

• Normal overjet and overbite
• Double retention including fixed retainer bonded from canine to canine in both dental arches and thermally formed removable splint

Exclusion criteria

• Fixed orthodontic treatment in one dental arch
• Extraction cases
• Patient treated with orthognathic surgery
• Imperfect treatment result due to treatment cessation on patients demand or health issues
• Craniofacial disorders

Trial design

100 participants in 1 patient group

Study group

Description:

From all the patients meeting the inclusion criteria every third patients was randomly chosen and invited to participate in the study. Written informed consent was obtained from every participant. Thus 100 patients have agreed to participate. All fixed retainers (stainless steel braided rectangular wire) were bonded in both arches by the same experienced clinician, who subsequently made impression for thermally formed splints and delivered them on the day of debonding. The effect of each of the procedures was verified by two independent experienced clinicians. On the day of debonding, directly following retainer bonding, intraoral scans were performed (T0). The patients were invited for repeating the scans after 1 (T1), 3 (T2) and 6 months (T3). The displacements were assessed by superimposition of the scans. The patients were recommended to wear removable retainers 22h/day. They were instructed to immediately report a failure and to apply immediately to the office in case of failure.

Treatment:

Diagnostic Test: Intraoral scan
