About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Non-extraction treatment
  • No hypodontia
  • Normal occlusion after treatment (Class I occlusion), perfect alignment
  • 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

Treatment and study plan

Intraoral scan

Diagnostic Test

On the day of debonding, directly following retainer bonding, intraoral scans were performed (T0), using 3Shape Trios 4 (3Shape, Copenhagen, Denmark). The scans were repeated after a month. The patients were invited for repeating the scans after 1 (T1), 3 (T2) and 6 months (T3).

Primary outcomes

  1. Tooth displacement in mm

    Time frame: One month after debonding

    Measurement obtained by comparing superimposed scans

  2. Tooth displacement in mm

    Time frame: Three months after debonding

    Measurement obtained by comparing superimposed scans

  3. Tooth displacement in mm

    Time frame: Six months after debonding

    Measurement obtained by comparing superimposed scans

Secondary outcomes

  1. Failure rate

    Time frame: Six months of observation

    Registration wherever the retention failure occured

  2. Compliance rate

    Time frame: Six months of observation

    Registration of patients attending to scheduled visits
