Abstract

Purpose: This study purposed to be introduced to evaluate the effect of the digital tray technique used on the accuracy of mandibular screw-retained implant overdentures compared with complete denture incorporated with barium sulfate as a radiographic stent. Materials and Methods: Forty-eight patients were examined for implant placement. Each implant site was planned virtually using two different techniques: denture duplication technique with barium sulfate incorporation and digital tray technique. Implantation placement had been performed in both groups using the same three-dimensional manufactured radiographic stent. Post insertion CBCT was introduced with simulated scheduling images. Angular deviation, global deviation, lateral deviation, and depth of implant placement were collected for planned and placed implants of both groups. Results: Using an independent t-test for significance assessment of global, lateral, and angular deviation between both groups, it was revealed that there was a significant difference between both groups and an insignificant difference for implant depth. Conclusion: Within limitations regarding radiographic accuracy depending on the radiographic technique; it showed less deviation of digital tray group than conventional denture duplication technique with barium sulfate incorporation.
