Przegląd systemu Quad

System formówek sekcyjnych Quad został zaprojektowany do tworzenia ciasnych, anatomicznych punktów stycznych w uzupełnieniach kompozytowych klasy II. Jest szczególnie skuteczny w przypadku uzupełnień kwadrantowych, w tym uzupełnień typu "back-to-back" w połączeniu z formówkami Firm Bands.

Końcówka prowadząca

Pierścienie Quad mają asymetryczną konstrukcję, ze standardową końcówką po jednej stronie i końcówką prowadzącą po drugiej. (Czerwone strzałki wskazują na końcówkę prowadzącą.) Kształt końcówki prowadzącej zapewnia precyzyjne dopasowanie do anatomii sąsiednich zębów, umożliwiając odbudowę typu back-to-back przy zachowaniu dużej siły separacji.

What problem are we solving?

Dentists frequently experience band destabilization and displacement when performing back-to-back Class II composite restorations using conventional sectional matrix systems. This concept addresses two critical moments of the procedure: 

  1. During Wedge Insertion 
    1. Matrix bands flare off the tooth before wedges are placed, allowing the wedge to catch the band and pull it off or mis-position it.
  2. During Ring Placement
    1. Placing the ring often displaces the band, causing loss of contact form, poor contour, or the need to restart the sectional matrix setup. 

Split-Wedge Technology

Quad’s split wedge technology is designed for superior matrix adaptation in composite restorations. These wedges feature a split design that adapts to tooth anatomy, seals cervical margins, and prevents flash, particularly useful for deep, tight, or subgingival restorations. They are particularly designed for complex / quadrant restorations including back-to-back Class II restorations. The Quad Band Wedge is designed to be an improved solution for back-to-back Class II restorations. 

Driver-Tip Technology

The Quad Rings have an asymmetrical design, with a standard tip on one side and driver tip on the other. (Red arrows point to driver tip.) The driver tip shape provides a precise fit to the anatomy of the adjacent teeth for a back-to-back restoration while maintaining strong separation force.  

The driver tip is meant to drive the Quad Band Wedge bands against the adjacent teeth and split the wedge.

When to Use It 

Since we only have one size of the Quad Band Wedge in this stage of development, the indication for use for these prototypes are simultaneous back-to-back Class II restorations on two molars. Please note that we plan on developing more sizes. 

We’ve also received qualitative feedback that this concept works best for back-to-backs involving either: 

  • Perio-teeth (not clinically short teeth) 
  • Large embrasures 
  • Non-conservative preps 

How to Insert It 

We typically recommend to insert the Quad Band Wedge on the narrower side of the prep / embrasure, which contradicts our recommendation of inserting regular Quad wedges into the wider side of the prep. This is because if you insert the Quad Band Wedge on the wider side, the bands tend to get caught on the prep during insertion.

We also recommend using Garrison’s BWI or BFA-1 instruments to insert the Quad Band Wedge. If you do not have these, cotton tweezers will likely work.

Which Ring To Use 

This concept is designed and engineered to be used with a Quad ring. If you are willing to test with a non-Quad ring, please do so as we will ask for feedback on that as well.

How to Place Ring

The concept is designed for the non-driver Quad ring tip to be placed over the grip block.
