Characterizing Orthodontic Tooth Movement With Photographic Scans

Characterizing orthodontic tooth movements in real time by using photographic scans to monitor teeth movement. The photographic scans will also be compared to 3D model scans. Canine retraction over the course of 1 orthodontic visit will be measured.

About this study

The accuracy and reliability of Dental Monitoring scans is be evaluated and compared to that of iTero digital scans during maxillary canine retraction. The magnitude and type of tooth movement occurring in a one month period in patients undergoing maxillary canine retraction will be measured. Patients undergoing orthodontic treatment in the Center for Orthodontic Care at UConn Health will be evaluated for the inclusion criteria. A total of twenty patients whose orthodontic treatment plan required extraction of at least one premolar in the maxillary arch will be recruited. The patient will be required to take photographs and video scans as dictated by Dental Monitoring (DM) on the first and final days of the study period (four weeks), while iTero scans are taken by the provider in clinic on these same days. Patient will also be periodically taking photographic scans at home using Dental Monitoring. The DM scans taken by the patient will be compared to the iTero digital scans taken by the provider. This can be done by superimposing the stereolithographic (STL) files created from each scan and assessing the amount of deviation between the 3D models. The types of tooth movement occurring during canine retraction in buccolingual, mesiodistal, and incisogingival planes will be quantified using Doctor Dashboard software available in DM. DM's 3D matching technology allows superimposition of teeth from each 3D model created per scan. Each tooth and its movements are graphed in a detailed manner to provide precise information about its type of movement.

Monitoring Canine Retraction

Primary outcomes

  1. Accuracy Between Patient-taken DM Scan and Provider-taken iTero Scan

    Time frame: Initial Deviation T0 (Baseline), Final Deviation T9 (34-37 days)

    Deviation between the photographic and intraoral scan will be measured via root mean square (RMS) in millimeters (mm).

Secondary outcomes

  1. Tracking Maxillary Canine Tooth Movement (Displacement)

    Time frame: T1 (3-5 days), T2 (6-9 days), T3 (10-13 days), T4 (14-17 days), T5 (18-21 days), T6 (22-25 days), T7 (26-29 days), T8 (30-33 days), T9 (34-37days).

    Magnitude of canine tooth movement for every 4-5 days during a one month period. Measurements will be done in mm in three planes of space. Measurement reported in mm at each timepoint is the cumulative movement up to that timpoint during the one month of monitoring of tooth movement.

  2. Tracking Maxillary First Molar Movement (Displacement)

    Time frame: T1 (3-5 days), T2 (6-9 days), T3 (10-13 days), T4 (14-17 days), T5 (18-21 days), T6 (22-25 days), T7 (26-29 days), T8 (30-33 days), T9 (34-37days).

    Magnitude of maxillary first molar tooth movement for every 4-5 days during a one month period. Measurements will be done in mm in three planes of space.

  3. Tracking Maxillary Canine Tooth Movement (Rotation)

    Time frame: T1 (3-5 days), T2 (6-9 days), T3 (10-13 days), T4 (14-17 days), T5 (18-21 days), T6 (22-25 days), T7 (26-29 days), T8 (30-33 days), T9 (34-37days).

    Magnitude of canine tooth movement for every 4-5 days during a one month period. Measurements will be done in degrees in three planes of space.

  4. Tracking Maxillary First Molar Displacement (Rotation)

    Time frame: T1 (3-5 days), T2 (6-9 days), T3 (10-13 days), T4 (14-17 days), T5 (18-21 days), T6 (22-25 days), T7 (26-29 days), T8 (30-33 days), T9 (34-37days).

    Magnitude of maxillary first molar tooth movement for every 4-5 days during a one month period. Measurements will be done in degrees in three planes of space.
