National Health Insurance Service Ilsan Hospital Reports Findings in Technology (Accuracy of a surface-based fusion method when integrating digital models and the cone beam computed tomography scans with metal artifacts): Technology

South Korea Daily Report

2022 MAY 31 (NewsRx) -- By a News Reporter-Staff News Editor at South Korea Daily Report -- New research on Technology is the subject of a report. According to news reporting originating in Goyang, South Korea, by NewsRx journalists, research stated, “The aim of this study was to evaluate the intra- and inter-observer reliability of maxillary digital dental model integration into cone-beam computed tomography (CBCT) scans to reconstruct three-dimensional (3D) skeletodental models for orthognathic patients. This retrospective study consisted of CBCT and digital maxillary dentition images of 20 Class III orthognathic patients.”

The news reporters obtained a quote from the research from National Health Insurance Service Ilsan Hospital, “After two repeated fusions of digital cast images with reconstructed CBCT images by a digital engineer and an orthodontist respectively, the 3D coordinate values of the canines, first molars, and central incisors were evaluated. The intra- and inter-observer reliability of 3D positions of maxillary teeth were compared using intraclass correlation coefficients (ICCs). Intra-observer reliability of x-, y-, and z-coordinate values of maxillary teeth showed significant and excellent agreement in an engineer (0.946 ICC 1.000) and an orthodontist (0.876 ICC 1.000). The inter-observer reliability of the y- and z-coordinates of each tooth was significantly excellent or good, but that of the x-coordinates showed insignificantly poor to moderate agreement. This study showed that the integration of maxillary digital models into CBCT scans was clinically reliable.”

According to the news reporters, the research concluded: “However, considering the low inter-observer reliability on the x-coordinates of dentition, clinical experience and repeated learning are needed for accurate application of digital skeletodental model in orthognathic patients.”
