Comparison of Scanning With and Without Rubber Dam for Overlay Restorations

NCT05735509 NA COMPLETED

The use of rubber dam when performing adhesive restorations improves the quality of the treatment. The widespread use of this type of restorations makes it increasingly necessary to use this type of isolation of the operative field. At the same time, the use of CAD/CAM systems in dentistry has recently become more widespread, which means that chairside systems are being used more and more frequently. Given that in indirect restorations it is necessary to place the rubber dam at the time of cementation, it has been proposed to take optical impressions of the preparation with the rubber dam already in place. For this it is necessary to have previous records that are cut out and rescanned. Since there are authors who have described that rescanning can cause defects in the meshes, in this work we try to compare both types of scanning in a specific type of restorations, the overlays. For this purpose, scans of the tooth preparation with and without rubber dam are taken, and a random decision is made on the basis of which scan the restoration is made. Then it is taken to the mouth and the marginal fit, contact points and occlusion of the restoration are evaluated. The results of the group made from the scan without dam are compared with those of the group made from the scan with dam. The two scans of each case are also compared to evaluate the differences.
