| Abstract | ||
| Aim: This study aimed to examine the influence of intraoral splinting of implant scan bodies on the trueness of data acquisition for fully edentulous arches using a simple technique to address dimensional discrepancies inherent in the stitching process of intraoral scanners. Materials and Methods: Thirteen edentulous patients with All-on-4 implants were included. A verified master model, obtained from conventional splinted open-tray impressions, was digitized as the reference. Each patient received two intraoral scans (Medit I700): one with non-splinted and one with splinted scan bodies (using dental floss and composite resin). Data were analyzed with 3D metrology software (Geomagic Control X) and compared using an independent t-test. Results: The splinted scan bodies (0.45 ± 0.07 mm) showed significantly higher deviation from trueness measurements compared to non-splinted scan bodies (0.12 ± 0.01 mm) as P = 0.0001. The splinted scan bodies recorded a significantly higher total clinical time (13 ± 1.47 minutes) compared to non-splinted scan bodies (8.08 ± 0.86 minutes) as P = 0.0001. Conclusion: Splinting of scan bodies using dental floss with composite resin has significantly decreased the scanning accuracy of the intraoral scans. Although splinting has decreased scan time, it has increased the total clinical time for full arch implant data acquisition. | ||
