Accurate transfer of the maxillo-mandibular relationship to an articulator (i.e.,
mounting) is critical in prosthetic treatment procedures. In the current study, a
PubMed search was performed to review the influencing factors for the maxil lo-mandibular relationship’s accuracy. The search included digital mounting as
well as conventional gypsum cast mounting. The results showed that a greater
amount of displacement was introduced during positioning the maxillary and
mandibular models to interocclusal records rather than the dimensional change
of registration material. Most intraoral scanners resulted in an accurate repro duction of the maxillo-mandibular relationship for posterior quadrant scanning;
however, the accuracy was declined as the scan area increased to a complete arch
scan. The digital mounting accuracy was also influenced by the image processing
algorithms and software versions, especially for complete arch scans.
