Abstract

Abstract: Objective To explore the clinical application of a dental post-processing module for cone beam CT (CBCT) images embedded within the picture archiving and communication system (PACS) for preoperative implant evaluation. Methods A PACS-embedded dental post-processing module, including curved planar reformation (CPR) and continuous multi-axis dental reconstruction, was developed. A total of 270 CBCT images from implant patients in our hospital (scanned using three different CBCT systems, 90 cases per system) were analyzed by a radiologist for bone volume assessment. Method1 used CBCT digital imaging and communication in medicine (DICOM) data uploaded to PACS, applying the embedded dental post-processing module for reconstruction and measurement. Method2 utilized CD-ROM data exported from each CBCT device along with the corresponding built-in image processing software. The durations of image upload, opening, post-processing, and total time for both methods were recorded and statistically analyzed. Consistency in bone volume measurements was assessed, and a questionnaire on user satisfaction was completed by 10 radiologists and implantologists. Results Significant differences in image processing times were observed between the two methods for all three CBCT systems. Method1 significantly reduced total processing time compared to Method2 (P<0.001), with consistent bone volume measurement results between the two methods. User satisfaction surveys indicated that Method1 was superior to Method2 (P<0.001). Conclusion The PACS-embedded post-processing module is suitable for CBCT image analysis and measurement in implant patients, significantly enhancing clinical efficiency.
