CATEGORY AUSTRALASIAN DENTIST63 Conclusion The use of the ReelMatrix™ system in clinical situations where an adjacent tooth is absent proves to be highly effective. Its adaptable matrix band provides an accurate fit around the tooth structure, allowing the clinician to properly reconstruct the proximal wall while closely reproducing the natural anatomical contour of the tooth. This facilitates improved restorative control, anatomical accuracy, and predictable clinical outcomes in challenging posterior restorations u About the author Dr María José Naranjo Cabezas is an Ecuadorian dentist specializing in restorative and aesthetic dentistry.

Figure 7: Two coats of universal adhesive were applied with active scrubbing, air-blown between each coat, and then light-cured. A 0.5 mm layer of flowable composite resin was placed on the floor and walls of the cavity and light-cured. The Garrison ReelMatrixTM was then positioned, and a matrix-in-matrix technique was used to achieve better sealing. Figure 10: After rubber dam removal, high occlusal contacts were identified and adjusted. Finally, the restoration was finished and polished. Figure 8: The proximal wall was built using the snowplow technique. Figure 11: X-ray, sealing evaluation. Figure 9: Once the Class II cavity was converted into a Class I cavity, the restoration was completed using a horizontal incremental technique.
