Proximal adhesive restorative techniques until now still suffer one shortcoming: Due to the linear axis of bur rotation, access to undermining caries still requires substantial sacrifice of sound hard tissues, and in most of the restored proximal lesions, more sound than infected tissue may be removed when conventional cavity designs are cut [15,16,17]. Therefore, tunnel restorations have been repeatedly discussed as possible alternative to conventional box-only fillings [18,19,20,21,22,23,24,25,26,27,28,29,30]. It is assumed to be advantageous that tunnel preps are less invasive and may make it easier to achieve a tight proximal contact [23,24,25,26]. On the other hand, both excavation and preparation are demanding to the operating dentist, and the risk to overlooked caries as well as fracturing lateral ridges is omnipresent in scientific literature of the field [24, 25, 27,28,29,30]. However, the predominant number of papers deals with glass ionomer cements where no adhesive stabilization is provided and fractures may be logical [31,32,33]. Also, the routine use of flowable composites to get easier access to undermining areas is not considered in most of the clinical studies [23].
A total of 229 patients received 673 proximal resin composite restorations. From 371 tunnel restorations, 205 cavities were filled with resin composite (Amelogen Plus) without flowable composite lining (group tunnel A). A total of 166 tunnels were restored with additional use of a flowable composite (tunnel B, i.e., application of a thin ( 2 mm (Fig. 5). In cases with near-to-complete or complete loss of the lateral ridge, a classical box-only preparation was cut. In a few cases, undermining caries toward buccal or oral aspects required extended access preparations and made tunnels impossible (Fig. 6).

The cavity preparation of tunnel restoration removes less tooth tissue compared to the conventional Class II box and slot preparation (Figure 1). The demineralised enamel in the interproximal surface can be preserved in a tunnel preparation if it is not cavitated. With the preservation of different amounts of enamel in the interproximal surface, the tunnel preparation can be classified as (1) total tunnel (complete removal of the demineralized proximal enamel), (2) partial tunnel (partial removal of the proximal surface with the preservation of some demineralized proximal enamel) and (3) internal tunnel (preservation of proximal enamel).11,13Figure 1 Tooth structure loss in cavity designs. (A) Class II preparation - removal of occlusal and proximal tooth structure including the marginal ridge. (B) Slot preparation - removal of proximal tooth structure including the marginal ridge. (C) Tunnel preparation - removal of occlusal and proximal tooth structure. 2ff7e9595c
