About this study

In this research, the investigators investigate the individual characteristics of the human upper and lower dentition and palate. The investigators use digital dentistry, record the data using an intraoral scanner, and store the extracted open source file format on a secure cloud-based server. Data validation is repeated annually. By comparing the initial and control digital samples, the investigators draw conclusions about the usability of the extracted information. The aim of the study is to develop a method and data storage protocol that will allow the patient data to be used years or decades later to replace or restore lost information.

Treatment and study plan

Intraoral scanning and data acquisition

Device

Intraoral scanner data acquisition, 3 scans are taken for each participant. Data will be exported from dedicated software (Planmeca, Romexis) and imported into GOM surface analysis software. Sample comparisons and sample preparation are performed here. The results are collected in excel spreadsheets and analyzed in SPSS statistical software.

Primary outcomes

  1. Deviation value between 3 human palatal scans

    Time frame: 30 second between data acquisition

    The deviation value will be measured in mm between three human palatal scans of the same individual by GOM Inspection software.

  2. Deviation value among scans

    Time frame: 30 second between data acquisition

    The deviation value will be measured in mm between 9 comparisons of twin siblings by GOM Inspection software.

  3. Deviation value between 2 scans

    Time frame: 30 second between data acquisition

    The deviation value will be measured in mm between 2 human palatal scans of the same individual by GOM Inspection software.

  4. Deviation value between original scans and mirrored scans of the individual

    Time frame: 30 second between data acquisition

    The deviation value will be measured in mm between the original human palatal scans and mirrored human palatal scans of the same individual by GOM Inspection software.

  5. Deviation value between original human palatal scans and mirrored human palatal scans of the twins

    Time frame: 30 second between data acquisition

    The deviation value will be measured in mm between the original human palatal scans and mirrored human palatal scans of twin siblings by GOM Inspection software.
