Method and system for creating three-dimensional virtual image of dental patient

Abstract

The invention provides a method and a system for creating a three-dimensional virtual image of a dental patient. The method for creating the three-dimensional virtual image of the dental patient comprises the following steps: acquiring facial scanning data, oral scanning data and cone beam CT jaw bone data of the dental patient; matching and correcting the face scanning data and the oral cavity scanning data to establish a face-dentition model; and aligning the cone beam CT jaw bone data with the facial dentition model according to the coordinates of the corresponding points of the dentition data so as to create a three-dimensional virtual image of the dental patient. By integrating CBCT, intraoral scanning and extraoral scanning data, a real virtual three-dimensional dental patient is constructed and serves as a more effective and visual diagnosis, planning, communication and education tool for dental technicians, clinicians and patients. In combination with CAD/CAM equipment and technology, dental aesthetic restoration and occlusion reconstruction can be realized more accurately and conveniently.

AI Technical Summary

Benefits of technology

The current methods used for making 3D images involve combining multiple scans into one composite picture that helps professionals see better detail about teeth or other parts during medical procedures. This makes it easier than just looking at them alone without actually taking their mouth offline.

Problems solved by technology

Technological Problem addressed in this patented technical problem involves creation of customized orthodontic brackets during surgeries due to factors like missing teeth caused by accidental drilling procedures or poor alignment from previous treatments. Current methods involve taking impressions before making any repairs, leading to potential complications including gingival recession, root resoφtion, and lack of esthealthy contact surfaces around posterior teeth. Additionally, current techniques require complicated workflow processes and tools to guide the process, resulting in increased costs compared to direct restoring without these featured materials.
