BurtonBands Posterior Matrix System
Class II composite restorations are one of the most common procedures performed by dental practitioners. Current matrix systems are inefficient and fail to produce consistent results, leading to high failure rates. The BurtonBands Posterior Matrix System is a ringless option that solves for many of these inefficiencies, while delivering superior aesthetics. Furthermore, the BurtonBands Posterior Matrix System and VursaWedge are compatible with current ring systems.
Problem: Flimsy matrices are difficult to place and wedge consistently.
Solution: The BurtonBands Posterior Matrix System accomplishes this in one simplified step. The wedge adds rigidity to the attached matrix, allowing it to be placed more easily and accurately.
Problem: After the matrix and wedge are placed, a ring system can cause the matrix to kink and lose its natural contour. This often results in overhanging margins and improperly contoured restorations.
Solution: The curved wings of the Split Wedge on the BurtonBands Posterior Matrix System help adapt the matrix to the buccal and lingual line angle contours of the tooth without the use of excessive pressure from a ring. This allows the practitioner to control where the proximal contact is being placed, which eliminates flash and reduces finishing time. If using a ring is preferred, the system is also compatible with most rings. The streamlined size of the matrix band allows the ring to engage the walls of the teeth without engaging the matrix, giving class II restorations perfect shape and contour.
Problem: Matrices and wedges can fail to seal the gingival margin of the proximal box, which leads to poorly adapted restorations and excess flash or overhangs.
Solution: The attachment of the matrix band to the flexible Split Wedge on the BurtonBands Posterior Matrix System consistently creates a seal at the gingival margin. It also allows the matrix to emerge at the correct angle, creating a properly-contoured restoration. The system also includes a Force Wedge to further enhance the gingival margin seal.
Problem: Rings create separation between the teeth but greatly reduce access to the area being restored, particularly when multiple restorations are being performed simultaneously.
Solution: The dual wedge system provides similar separation without the need for a ring, which results in greater access to the restoration. The opposing Force Wedge applies uniform pressure on the Split Wedge, gently pushing the teeth apart as it is inserted.
Problem: Certain matrices are oversized in both height and width, which is necessary to provide surface area for a ring to grip. However, excessive size results in decreased access and over-filling of the cavitation without line of sight to the adjacent tooth, which increases finishing time.
Solution: The BurtonBands Posterior Matrix System uses the correct height and contours, which allows for marginal ridge shaping in line with the adjacent tooth. This reduces finishing time and creates naturally contoured restorations.
