Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Up to 30 Participants in the intervention group will have treatment with aligners and be recalled based on the recommendations of the AI-guided Dental Monitoring(TM) system. This system uses a smartphone application that allows patients to take accurate intraoral photos, software that measures individual tooth movements and an internet-based interface where the clinician can monitor patient records and correspond with the patient. Participants will provide intraoral photographs once weekly, with each "scan" taking approximately 5 minutes. Participants will be provided standardised instructions on how to use the DM system. Participants will use the DM system until treatment is completed. On average, this takes 12 to 18 months. Reminders for the patient to submit their scans will be sent via the DM application, and the researchers will be notified if participants fail to submit their intraoral photos.
Participants will be recalled to return to the clinic for attachment placement, interproximal reduction as required. Orthodontic treatment will be provided by general dentist supervised remotely by orthodontists.
Instructions will be provided via a pamphlet with illustrations. Instructions have been designed specifically for the study.
The orthodontist will determine if treatment is complete.
Intervention code [1] 326397 0
Treatment: Devices
Comparator / control treatment
Up to 60 patients who meet the selection criteria and are able/willing to be seen face-to-face at SDH will be selected from the orthodontic waiting list and form the control groups (Up to 30 per group). These patients will be treated by the orthodontic specialist student cohort and consent to have face-to-face appointments at Sydney Dental Hospital (SDH). Positive and Negative Control Groups will be based on the use aligners or braces (respectively) for treatment.
Participants will be booked in for their next appointment based on recommendations from their treatment team like in usual orthodontic treatment with braces or aligners. Controls will not use DM system.
Control group
Active

Outcomes
Primary outcome [1] 335189 0
Completion of orthodontic treatment measured using 1) an internationally validated scoring system (Peer Assessment Rating (PAR) score & Objective Grading System (OGS)) and routinely collected clinical data. 2) Patient centred care outcomes: patient perception of improvement in appearance and Quality of life assessment in relation to experience of care using validated questionnaires (Oral Health related Quality of Life Questionnaire).
this will be assessed as a composite outcome.

Data to be collected:

Peer Assessment Rating (PAR) Index (Pre and Post treatment):

Upper and lower anterior segments contact displacements; clinical assessment
Buccal Occlusion: clinical assessment
Overjet: will be assessed using a ruler
Overbite; will be assessed using a ruler
Centreline; will be assessed using a ruler

Objective Grading Score (OGS) (Pre and post treatment)

Alignment
Marginal ridges: clinical assessment
Buccolingual inclination; will be assessed using a ruler
Occlusal contact: clinical assessment
Occlusal relationship: will be assessed using the Angle's relationship
Overjet; will be assessed using a ruler

Timepoint [1] 335189 0

Clinical data will be routinely collected at each appointment until completion of orthodontic treatment.
At the end of treatment: Completion of orthodontic treatment will be measured using 1) an internationally validated scoring system (PAR score & OGS).2) Patient centred care outcomes: patient perception of improvement in appearance and Quality of life assessment in relation to experience of care using validated questionnaires (Oral Health related Quality of Life Questionnaire).
Primary outcome [2] 335190 0
This will be assessed as a composite outcome.
Process outcomes (3, 12, 24 months): Patient compliance and patient and clinician fidelity will be compared in relation to outcomes. Quantification of patient compliance in the DM and Control groups will be assessed by checking missed scans and appointments respectively. Data will be collected via audit of patient records. Compliance with treatment procedures will be checked via patient questionnaires and the total number of successfully completed treatments. To assess if the intervention was delivered as intended, checklists will be used. These questionnaires have been designed specifically for the study.
Timepoint [2] 335190 0
3, 12 & 24 post commencement of treatment.
Primary outcome [3] 335191 0
This will be assessed as a composite outcome.
Acceptability/Experience of care (3, 12, 24 months): measures will include satisfaction/experience of patients.
Uptake of proposed intervention, impact of travel time and time off work/school.
These composite outcome data will be collected via a specific questionnaire designed for this study.
Timepoint [3] 335191 0
3, 12 & 24 months post commencement of treatment
Secondary outcome [1] 423421 0
Economic evaluation to compare remote specialist orthodontic treatment with conventional orthodontic treatment. The cost of treatment in the three arms will be compared.
Data of cost of treatment will be collected via audit of patient records.
