Restoration of Proximal Contact in Direct Class II Resin Composites

Abstract

Although this technique performed well in the case presented, it becomes more advantageous with larger restorations. This would be especially true for core build-up restorations of missing cusps, although such cusps must be restored prior to placement of separating rings. Clear plastic matrices are available and permit effective curing of resins, but the authors find the preset contours of these matrices not sufficiently adaptable to differing clinical situations and prefer metal matrices, even though these necessitate additional light curing after matrix removal.

Comparison of Proximal Contact and Contours of Premolars restored with Composite Restoration using Circumferential Matrix Band with and without Separation Ring: A Randomized Clinical Trial

“…With results (Table 2), we inferred that it is the separation ring that is mainly responsible for the tighter contacts. Use of a separation ring along with circumferential matrix was first proposed by Bracket et al 19 As it was a case report; hence, the evidence in its favor was weak. Our study has attempted to employ an unusual combination and to the best of our knowledge, no trial has ever combined these together before, thus, our technique is innovative.…”

The Influence of Matrix Type on the Proximal Contact in Class II Resin Composite Restorations

“…[1][2] This objective pertains to reproducing the natural proximal contour of a contact that is tight enough to prevent food impaction, which is crucial for the healthy maintenance of underlying periodontal tissues. [3][4][5] Increased gingival inflammation and attachment loss, apart from the presence of overhanging restorations, [6][7] have also been attributed to plaque accumulation due to loose proximal contacts.…”

New Technique for Wedge Selection in Direct Class II Restorations: A Pilot Study

“…Restoring the approximal anatomy in a Class II direct restoration presents a significant challenge in restorative dentistry [ 25 ]. When this anatomy is not accurately reconstructed, adverse outcomes such as masticatory discomfort, caries, periodontal problems, and undesired movement of teeth may arise; restoration of the approximal anatomy is a big challenge [ 7 ].…”
