Agreement and reproducibility of intraoral scan- versus CBCT-based three-dimensional implant position assessment in the posterior mandible - a paired in vitro method-comparison study

Background

Three-dimensional postoperative implant assessment is increasingly performed using intraoral scan (IOS) superimposition as a radiation-free alternative to cone-beam computed tomography (CBCT). However, it remains unclear to what extent IOS- and CBCT-based measurements agree and how reproducibility changes across posterior mandibular configurations.
