Scientific titleEffect of AI-enhanced visual simulations and explanations on patient understanding and acceptance of orthodontic treatment: a randomized controlled trial
Study acronymAIOPA
Study objectives1. To determine whether AI-enhanced communication increases treatment acceptance within 14 days of consultation compared with standard consultation.
2. To assess differences in patient comprehension scores between AI-enhanced and standard consultations.
3. To compare decisional conflict, decisional regret, satisfaction, and trust in the clinician between groups.
4. To measure differences in consultation duration and clinician workload.
5. To explore whether demographic or clinical variables (age, sex, education, electronic health literacy (eHealth literacy), malocclusion severity, treatment type) modify the effect of AI-enhanced communication.

Health condition(s) or problem(s) studiedPatient understanding and acceptance of orthodontic treatment
InterventionParticipants will be allocated in a 1:1 ratio using a computer-generated randomisation sequence with concealed allocation via sealed opaque envelopes opened only at the time of consultation. Outcome assessors will remain blinded to group assignment.

Control group (Standard consultation): The orthodontist explains the patient’s condition and treatment options using the diagnostic records (photos, radiographs, tracings, and models) together with a generic printed brochure about orthodontic treatment and appliance care.

Intervention group (AI-enhanced consultation): Patients receive all elements of the control consultation plus AI-generated visual simulations, plain-language explanations (Kurdish) and a digital take-home summary via QR code. Consultation duration is kept similar between groups.

AI-Generated Visual Simulations
Individualized treatment simulations will be generated using 3Shape OrthoAnalyzer™ software, version 2025.1 (3Shape A/S, Copenhagen, Denmark). The software integrates AI-based algorithms trained on extensive orthodontic datasets to simulate predicted outcomes of malocclusion correction.
Baseline diagnostic records, including intraoral and extraoral photographs, lateral cephalograms, and digital study models obtained via intraoral scanning, will serve as input data. The system produces:
- 2D before–after overlays superimposed on facial and intraoral photographs,
- 3D interactive digital models illustrating predicted tooth alignment and occlusal changes, and
- Animated treatment progression sequences that demonstrate key transitional stages and the anticipated final result.

To ensure consistency and reliability, all simulations will be generated following standardized parameters embedded in the software (e.g., correction of crowding, overjet reduction, arch coordination). Each simulation will be reviewed by the investigator for clinical plausibility prior to presentation. During the consultation, patients will view the simulation on a tablet, and a secure QR code will be provided to access the same materials at home.

The simulations are intended exclusively as decision-support and communication tools to enhance patient comprehension and confidence; they do not replace the orthodontist’s diagnostic judgment or definitive treatment planning.

Total duration of intervention: Each participant receives a single orthodontic consultation session (with or without AI-enhanced communication depending on the allocation arm).

Total duration of follow-up: 14 days after the consultation, during which treatment acceptance and secondary outcomes are assessed.
