Brief Summary:
The orthodontist uses plaster models to collect information This includes identification deviations classification of malocclusion formulation of treatment goals for specific patient Models are used to examine the morphology of individual teeth and also to visualize the placement of teeth in individual dental arches Study models It therefore appears to be one of the most important records for treatment planning
In USA orthodontist can start practicing orthodontics which requires a lot of difficulty 300 new cases in a year and therefore may require an entire room to store plaster models The minimum file retention period depends on the appropriate platform for the statute of limitations during which legal action for fault can be brought in the USA this time period varies from 5 to 15 years varies from country to country
This platform can be started on the last day of treatment or it can be postponed until the patient reaches adulthood Regardless of how it is viewed long term storage is required Over ten years if 300 new cases are initiated each year that will represent 6000 combinations of prototyping pre-processing and post-processing Additional storage space may be required maybe somewhere else with financial implications
With the recent introduction of digital models and CBCT images the orthodontist now has an alternative to traditional plaster study models Digital technology makes it possible to analyze a computer using software capable of rotating examining and measuring digital images of the model and dental arches from different points of view The intraoral scanner is a hand-held device that creates digital impressions of the oral fossa and displays it in 3D on a computer screen after being processed by the scanning program for each device By 1985 the first intraoral scanner was available for commercial use and over time it had evolved to become smaller faster and more accurate Intraoral scanners provide easier treatment planning better workflow greater patient acceptance and shorter working time but more studies are needed to investigate their accuracy and compare with traditional methods The measurements of the tooth widths are one of the important elements in orthodontic diagnosis because of its role in calculating the partial and total Bolton ratio the Ton relationship and space analysis Therefore the aim of this study will be to assess the accuracy and reliability of measuring teeth widths and Bolton ratios based on three mains well -known methods plaster models CBCT images and intraoral images to ensure the safety of orthodontic diagnostic outputs

Detailed Description:
Several published studies analyzed teeth widths and Bolton ratios using CBCT with plaster models two-dimensional images or three-dimensional images as the gold standard and applied to patients or skulls but they did not use the sagittal axis orientation method for each tooth on the limit to determine its precise lateral mesial width but the method of unified orientation was adopted in the transverse plane
The most important benefit of the CBCT is that the measurements are made directly on the digital model which eliminates the possibility of error that can occur with traditional methods alginate blending alginate hardening casting or some other digital methods such as scanning plaster model
The special orientation method was adopted for each tooth separately so that the three axes of the software are perpendicular to the longitudinal axis of the tooth and the maximum mesio-lateral width is determined on both the axial plane and the transverse plane and the measurement is made on each of them which is supposed to be identical in the case of correct orientation
This method is useful for determining the width of each tooth regardless of its position within the dental arch or overlapping it with other teeth
The intraoral scan is the latest innovation in dentistry to generate three-dimensional models that can be studied and many tests were conducted on it to determine its accuracy and reliability by determining teeth widths and the Bolton ratios with the adoption of plaster models or two-dimensional images as a gold standard
Looking at the published medical literature and in an attempt to find a study similar to the current study It was found that the comparisons regarding teeth widths measurements were among plaster models as a gold standard and CBCT images or between plaster models as a gold standard and IOS images and no study was found that made a comparison Triple among the previous three methods
