About sectional matrix systems
A sectional matrix system rebuilds one surface between two teeth at a time: a short pre-contoured matrix is chosen by the size of the tooth, placed between the teeth and secured with a sectional ring and a wedge. Pre-contoured sectional bands were introduced to overcome a shortcoming of the band that goes around the whole tooth: with composite it tends to flatten between the teeth, because of the tension in the band and the low resistance of composite to deformation. That flattening moves the contact towards the top edge of the tooth, which lowers the strength of the contact and makes food packing more likely. Some sectional matrices are supplied as a single piece of stainless steel with the wedge already attached, inserted from the cheek side or the tongue side.
A matrix system creates a temporary wall against which the restorative material is packed, so that the contact between neighbouring teeth, its form and its function can be rebuilt. It also helps shape the restoration and reduces the excess that would otherwise spread at the gum line. What is wanted at the end is a tight anatomical contact area, which prevents food impaction, recurrent caries, periodontal disease and tooth movement.
What a sectional system is made of
The ring: every study in one systematic review found that a separation ring with the sectional matrix raised the tightness of the contact. The same review notes that no research has yet compared a sectional matrix used with a separating ring against the same matrix used without one.
The wedge: it seals the matrix at the gum line, adapts it to the cervical contour, holds it steady and separates the teeth a little on its own.
Kits and refills on this shelf pair rings, matrices, wedges and the forceps that place the ring.
What to look at when choosing a system
Number of surfaces: in two-surface cavities a separating ring gave tighter contacts, while in three-surface cavities one trial found no statistically significant difference between the two systems.
Handling: in one survey 57.1 percent of students put the difficulty of the sectional system down to a lack of training or expertise, and 48.6 percent said the circumferential one needed extra time for placement.
Shape: a review notes the rounded contour of a sectional matrix does not always conform to the natural proximal contour, and that close contacts between teeth can make it hard to insert without denting it. Adaptation: a clinical study concluded that appropriate adaptation of the matrix system helps establish successful proximal restorations.
