Abstract:

Objectives: Several software packages report ability to perform different procedures, but results are sometimes inconsistent among software, making it difficult for a practitioner to communicate and compare values. Aim: To compare 3D voxel based superimposition CBCT in 2 different imaging software programs

Methods: Pretreatment (T1) and post treatment (T2) CBCT scans of 15 adults and 15 teenagers were used to compare voxel based superimposition between Dolphin3D and OnDemand3D. Superimposition was on the cranial base. The registration of T2 scans were exported as DICOM files and compared using closest point color map using slicer3D software.

Results: 10 cases were used to assess reliability, and intraclass correlation analysis was ≥0.98. The mean differences between the programs were 0.5±0.06 mm for teenagers and 0.25±0.03 mm for adults, which is clinically insignificant

Conclusions: Both Dolphin3D and OnDemand3D are reliable and deliver the same voxel-based cranial base superimposition results
