The decision on aligner changing is based on orthodontists' personal experience and common knowledge that an approximated time span for the aligner have exhausted its biological efficacy. However, a one size fits all approach is not always ideal, as an average determined time is not taken into account of a patient's individual biological response. The aligners could be progressed earlier than the determined time, or they may stay inactive for a while, waiting for the in-office visit. Dental MonitoringTM is the only available technology that provides 3D monitoring of teeth movement, reconstructs 3D digital models remotely, and auto-detect clinical situations by their patented AI algorithms. The investigators have reported high accuracy of DMTM to monitor the tooth movement in vitro. However, the efficacy of DMTM on orthodontic treatment and the accuracy of DMTM in the orthodontic patients has not been investigated yet. In this proposal, the investigators are implementing the Dental MonitoringTM application and 3D tracking of tooth movement powered by AI algorisms as a novel tool to customize aligner changing intervals. The ultimate goal is to reduce in-office visits and treatment duration while maintaining regular monitoring, thus not jeopardizing expected results. It is imperative to investigate the Teledentistry for its effectiveness, reliability, ease of use, patient satisfaction, and value on the overall health and oral health system, especially as a critical tool during public health emergency situations.

Clear Aligners with Dental Monitoring
DeviceDental Monitoring™ (DM ™). This digital technology software allows orthodontists to monitor patients remotely through continuous analytics using control vision technology, metaheuristics, and artificial intelligence.31 This app utilizes a patented artificial intelligence machine learning algorithm to calculate 3-dimensional (3D) tooth movements from intraoral photos and videos that patients capture using their smartphone cameras.

The number of aligners trays completed with an adequate fit
The primary outcome, the number of trays completed with an adequate fit after 6, 12 months and end of treatment (treatment length ranged 18-30) months.
Number of refinements plans
Number of refinement aligners
The ratio of added trays(refinement)/planned trays.
ABO Discrepancy Index
The higher the ABO DI score, the more complex the case. Therefore with treatment progress, the DI Score should Decrease at least 1 point from the ABO DI score before treatment.
The American Board of Orthodontics (ABO) Objective grading system (OGS)
The ABO score for the case is calculated by summing the scores for the 8 categories. The casts are scored in 7 categories (alignment, marginal ridges, buccolingual inclinations, occlusal relationships, occlusal contacts, overjet, and interproximal contacts), and panoramic radiographs are scored according to the single category of root angulation. If fewer than 20 points are scored overall, the case is considered to meet the ABO standard. If 20 to 29 points are scored, then the standard of work is undetermined. If more than 30 points are scored, the case is considered unacceptable.
Degree of tooth movement
3D Comparison Analysis will be performed to evaluate the treatment progress using a sophisticated processing software package (Control; Geomagic, Research Triangle Park, NC). Furthermore, each 3D digital dental scan at T3 will be superimposed on the 3D Digital model of the corresponding treatment stage in the aligner software (representing the ideal outcome).To determine the degree of tooth movement achieved with respect to the prescription, the following formula will be applied to each movement of each tooth. 1-(Ideal outcome-treatment outcome)/(Ideal outcome- Pre-treatment)
