AVINENT continues to collect the successes of collaboration with multiple professionals in the sector to research and disseminate new advances, studies and conclusions for the progress of the dental sector.

On this occasion, a new study by Dr. Marta Revilla joins the list of new articles published last February. You can consult the complete edition of the American magazine at this link. Below, we make a brief summary of the article and its main conclusions.

Accuracy of the implant replica positions on the complete edentulous additive manufactured cast. Olea-Vielba M, Jareño-García D, Methani MM, Martinez-Klemm I, Revilla-León M. J Prosthodont. 2020 Apr 26. doi: 10.1111/jopr.13179. Online ahead of print.

Summary

A definitive implant cast should be an accurate representation of the 3-dimensional (3D) position of the implants in the patient’s mouth. When using conventional impression technique, many factors can affect the accuracy of the impression for multiple implants.

The purpose of this in vitro study was to compare the linear and angular implant replica position accuracy on complete edentulous maxillary casts either made of dental stone or additive manufactured polymers using a coordinate measuring machine (CMM).

A complete edentulous maxillary cast with 6 implant replicas was prepared. The definitive cast was duplicated using two manufacturing procedures namely conventional (CNV group) and additive manufacturing procedures (AM group).

No significant differences were found between the two groups. Material jetting AM technology demonstrated no significant difference in trueness and precision values of the linear and angular implant replica positions when compared to the conventional technique.
