Using a Ceramic-Filled Nanohybrid Resin Composite for Same-Visit Restorations

The patient presented with a large carious lesion on the distal of tooth #3, requesting a same-visit solution. I determined that the glidewell.io™ In-Office Solution — including the fastscan.io™, fastdesign.io™ and fastmill.io™ workflows — would enable me to plan, design and mill a restoration that would meet these needs and exceed the patient’s expectations. I chose the CAMouflage® NOW resin milling block to create the restoration because the material can be milled quickly, while the well-documented and reliable bonding procedure provides much needed structural support for the remaining tooth structure.

Figure 5: I utilized an Exposé® Disposable Caries Indicator (Centrix; Shelton, Conn.) to ensure that all diseased tissue was excavated without removing more tooth structure than necessary. After caries removal, I placed 3M™ Vitrebond™ Light Cure Glass Ionomer Liner (3M; St. Paul, Minn.) to protect the pulp. This was the final step before taking digital scans.

Figure 9b: CAMouflage® NOW block, shade A2 back

Figures 9a, 9b: The restoration was milled from a CAMouflage® NOW block, shade A2. I chose the CAMouflage NOW resin milling block due to the material’s quick milling time in addition to its well-documented and reliable bonding procedure, which will provide much needed structural support for the remaining tooth structure. Per the patient’s preference, this allowed the restoration to be accomplished in one visit.

Figure 12: The post-treatment radiograph shows the restoration of the large carious lesion. While the patient had no symptoms after the procedure, as a precaution, he was informed that an endodontic procedure may be required at some point.

CONCLUSION

This case shows the restoration of a relatively large carious lesion with a conservative restorative strategy. Thanks to the digital workflow and my in-office mill, the patient left the chair with most of his remaining tooth structure intact. Most importantly, the patient was pleased with the result and the speed with which it was achieved.
