Evaluation of Implant Impression Accuracy Using Different Trays and Techniques with a 3D Superimposition Method.

Plastic and metal stock trays or conventional and 3D-printed custom trays can be used to obtain implant impressions for maxillary partially edentulous arches with similar dimensional accuracy. The five tray types and two techniques may be safely used to obtain impressions of partially edentulous maxillary arches with three implants.
