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 6,000 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.

Conditions

  • Malocclusion

Interventions

DIAGNOSTIC_TEST

Plaster models

The impressions taken of the dental arches will be poured with hard gypsum in order to make use of the models for taking measurements. These measurements will be considered the gold standard.

DIAGNOSTIC_TEST

CBCT images

All patients have been undergoing CBCT scans for both jaws

DIAGNOSTIC_TEST

IOS images

The patient's teeth have been dried with air syringe and scanned with the Intraoral scanner
