ReelMatrix as a Predictable Tool for Margin Elevation and Core Build-Up Prior to Indirect Restorations

Background

A 23-year-old male patient present to the clinic reporting pain in the upper right quadrant. Clinical examination revealed defective restorations and secondary caries.

Figure 1: 

Radiographic evaluation showed extensive carious lesions beneath the existing restorations.

Figure 2: 

After endodontic treatment of tooth#1.4, the provisional material from tooth #1.4 and the old restoration and carious lesion on tooth #1.5 were removed.

Figure 3:

Due to the extension of the carious lesions, the cavity margins on both teeth were located at a subgingival level.

Figure 4:

After completing the adhesive protocol using a universal adhesive system, it was decided to perform margin elevation and core build-up using he ReelMatrix system.

Figure 5:

A highly filled flowable composite resin, G-ænial Universal Injectable by GC, and Solare composite resin by GC were used for the restorative build-up.

Figure 6:

Once the build-up was completed, the matrix bands were removed, and both teeth were prepared to receive indirect restorations.

Figure 7:

In a third appointment, the indirect restorations were cemented.

Conclusion:

The ReelMatrix system provided an efficient and predictable solution for managing subgingival margins. Its versatility allowed not only for effective margin elevation, but also for the reconstruction of compromised tooth structure prior to the placement of indirect restorations, enabling proper anatomical contouring and facilitating a more controlled restorative workflow.
