Registered outcomes 2
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Clinical effectiveness | 6 months | comparing clinical effectiveness of directly 3D printed retainers vs thermoformed retainers fabricated by both positive and vacuum-pressure techniques was done using Geomagic software measurement of ( Little's irregularity index , inter-molar, inter-canine widths) between original and follow up scans. unit for all variables measured was mm. | ClinicalTrials.gov |
| Secondary | patient satisfaction | 6 months | comparing directly 3D printed retainers vs thermoformed retainers fabricated by both positive and vacuum-pressure techniques regarding patient satisfaction was done through visual analogue questionnaire on both day of delivery and follow up visit after 6 months. The questionnaire consisted of the following questions: Q1 Do you find your retainer comfortable? Q2 Do you like your retainer colour? Q3 Does the retainer have any weird taste? Q4 Does the retainer affect your speech? | ClinicalTrials.gov |
