Accuracy of Intraoral Scanning of Implant Level Impression Technique Versus Abutment Level Impression In Implant Mandibular Supported Overdenture. In-Vitro Study
Intraoral scanning has recently been investigated showing high accuracy in complete implant supported cases. The aim of this in vitro study was to compare the accuracy of intraoral scanning techniques for implant level impression versus abutment level impression techniques in patients with mandibular supported overdenture. Methods: Ready-made scannable foam cast of completely edentulous mandible was scanned using the extraoral scanner representing an edentulous mandible where four implant were placed. This cast was used as the control group; which was used to fabricate one cast with the implant level impression technique and the other to fabricate cast with abutment level impression technique as interventions. For both interventions; Digital intraoral scans (DIOS) were made after connecting implant level scan bodies to the master cast and STL files were exported to be used in the superimposition by a MEDIT COMPARE software for determining the accuracy of both techniques. Results: There was a statistically significant difference between (Implant level) and (Abutment level) where (p=0.008). Conclusion: The implant level impression technique is more accurate than the abutment level impression technique when using Digital intraoral scanning.
