Besides, working in a virtual environment shortens the time required for each procedure. Digital models can be used successfully for orthodontic diagnosis and treatment planning. The transformation of orthodontic plaster models into digital models is gaining popularity due to the superiority of digital models to plaster models in storage, retrieval, and sharing of information. In this respect, there is a need to retain dental models for long periods, with associated problems of storage, risk of damage or even loss. Besides, they are essential for educational purposes, evaluating treatment progress, and research reasons, not to mention their medico-legal significance. The plaster models are indispensable, because they are considered the cornerstone gold standard in orthodontic diagnosis and treatment planning and cases documentation. The biggest obstacle facing the paperless orthodontic office is the plaster study model. The paperless setup has been one of those technologies introduced to the orthodontic practice. The orthodontic discipline has been embracing new technologies over the past years. Of digitization of the alginate and rubber base impressions.

The most accurate digitization technique was the 3 Shape laboratory scanner Was no difference between the digitization using the intraoral scanner or the That all variables exhibited good to excellent reliability. Intra-observer reliability analysis for 14 out of the 16 measurements showed Results: Smallĭifferences between the plaster and digital models were observed. Tabulated and subjected to statistical analysis. Mesiodistal width of the 1 st permanent molar, 1 st premolar, canine and central incisor and arch width. Measurements included intermolar width, interpremolar width, intercanine width, Impression, and plaster model of their rubber base impression were done. Intra-oral scanning of the subjects and extra-oral scanning of theirĪlginate impressions, plaster models of the alginate impression, rubber base

Scanners evaluated in this study were Sirona (CEREC Omnicam) and 3 shape (TRIOSģ), while the laboratory scanners used were Sirona (inEos X5), and 3 shape Male and female subjects were randomly selected for this study. Obtained through intraoral and extraoral scanning modalities to the reference Aim of Study: To evaluate the diagnostic accuracy of 3D digital models Technology researches are necessary to evaluate their accuracy and reliability. With the advent of new scanners with better scanning Models have shown digital models to be valid, clinically acceptable, and more Studies assessing the accuracy of digital

Digital models can be obtained from alginate impressions as Introduction: Digital models showed promising results for orthodontic diagnosis and
