Comparative trueness of complete-arch implant position acquisition using auxiliary geometric device-aided and noncalibrated scanbody-based intraoral scanning versus smartphone-based and dedicated extraoral photogrammetry.
PURPOSE To compare the trueness of four techniques for complete-arch implant position acquisition: intraoral implant scanning (IOIS) using auxiliary geometric devices (AGDs), IOIS using horizontally extended noncalibrated scanbodies (NCSBs), smartphone-based extraoral photogrammetry (EPG), and EPG with a dedicated scan...
