Summary

Purpose: To determine if adjustment of full-arch zirconia frameworks processed on a model obtained with an intraoral scanner and an auxiliary device is not inferior to that of identical frameworks obtained from an elastomeric impression.

Materials and methods: Eight consecutive patients ready for a full-arch rehabilitation on already osseointegrated implants were selected. Two sets of impressions were taken, one open tray with polyether and splinted impression copings and a second one with an intraoral scanner. A verification plaster jig was used for the elastomeric impression and a prefabricated auxiliary device was used to adjust the optical intraoral impressions. Two full-zirconia frameworks with the same design were processed and tested on the patient by two independent calibrated operators. Accuracy of both frameworks was measured by calibrated blinded operators, who determined tactile adjustment, Sheffield test, radiographic adjustment, and screwing torque. Overall perception of adjustment was used to determine the better framework to be delivered to the patient.

Hº: Frameworks obtained from an impression taken with an intraoral scanner are not inferior in accuracy to those obtained from a conventional elastomeric impression

Conditions

  • Edentulous Jaw

Interventions

DEVICE

Clinical adjustment

Accuracy of the framework is checked in the patient mouth by tactile perception, screwing torque, Sheffield test and radiography.
