Background

Class V lesions are a common finding in adult patients typically due to abrasion, erosion, or caries. In the absence of caries, abfraction lesions can occur due to tooth flexure, acid erosion, or aggressive brushing. Non-carious Class V lesions can be repaired efficiently and effectively without the need for local anesthesia or tooth preparation utilizing the Garrison BlueView™ Cervical Matrices system and a resin modified glass ionomer cement (RMGI). According to the American Dental Association’s evidence-based clinical practice guideline on restorative treatments for caries lesions, patients receiving RMGI Class V restorations were less likely to experience restoration loss or marginal adaption issues “by an important amount” compared to patients treated with hybrid resin composite.

Procedure

In the following case study, non-carious Class V lesions were restored with RMGI (Fuji II LC, GC America) using the Garrison BlueView™ Cervical Matrices system.

Conclusion

This case demonstrates that non-carious Class V lesions can be restored in a conservative, efficient, and highly predictable way without the need for local anesthesia or tooth preparation. I chose the Garrison BlueView™ Cervical Matrices because they are specifically designed for these restorations, making it much easier to achieve proper contour, adaptation, and a smooth final result than with a more traditional approach. In my hands, they simplify a procedure that can otherwise be technique-sensitive and time-consuming.

My takeaway for other dentists is that success in cervical restorations is not just about material selection, but also about using armamentarium that is designed for the clinical situation. When paired with RMGI, the Garrison BlueView™ Cervical Matrices help streamline placement, reduce finishing, and support excellent esthetic and functional outcomes. For patients, that means a more comfortable and minimally invasive experience. For clinicians, it means a restoration that is efficient and predictably successful.
