Abstract

Accurate transfer of implant positions in full-arch impressions remains a critical challenge due to potential dimensional distortion associated with conventional splinting materials. Therefore, it is of interest to compare the linear dimensional accuracy of 3D-printed splinting materials with traditional splinting methods in full-arch implant impressions. A controlled in vitro study design was employed using a standardized edentulous model with multiple implants, where impressions were made using both splinting techniques and evaluated using digital measurement tools. The results showed significantly improved dimensional stability and reduced distortion with 3D-printed splinting materials compared to conventional acrylic resin-based splinting. Thus, data shows the superiority of digitally fabricated splinting materials, highlighting their potential to enhance prosthetic accuracy in implant dentistry.
