“…The most obvious deterioration among the present restorations was marginal adaptation, which was observed in 58.1% (Alpha score) of restorations after 3 years. Marginal gaps develop over time with exposure to the oral environment, because of differences in the coefficient of thermal expansion and surface wear (20). An incremental filling technique, combined with a low configuration factor, may reduce damaging polymerization shrinkage stresses and maintain satisfactory adaptation of a restoration (21).…”

“…Surgical margin relocation can address this (17) but is associated with attachment loss and anatomic complications because of the proximity to root concavities and the furcation area (18). As an alternative to periodontal surgical procedures, the cervical margin can be elevated coronally by applying bonding and resin composite materials (19), in accordance with proximal box elevation technique (20)(21)(22)(23)(24)(25), also referred to as cervical margin relocation (CMR) (26)(27)(28), deep margin elevation (18), or open-sandwich technique (29)(30)(31)(32). CMR can be performed with hybrid or flowable composites, after placing the metal matrix and interproximal wedge.…”

Abstract:We investigated the effect of cervical marginal relocation (CMR) on marginal sealing with two different viscosity resin composites, before adhesive cementation of composite computer-aided design/ computer-assisted manufacture mesio-occluso-distal (MOD) overlays. Standardized MOD cavities prepared in 39 human molars were randomly assigned to three groups. The proximal margins on the mesial side were located 1 mm below the cementoenamel junction. On the distal side of the tooth, the margins were located 1 mm above the cementoenamel junction. In Groups 1 and 2, mesial proximal boxes were elevated with a hybrid composite (GC Essentia MD) and a flowable composite (GC G-aenial Universal Flo), respectively. CMR was not performed in Group 3. The overlays were adhesively cemented, and interfacial leakage was quantified by scoring the depth of silver nitrate penetration along the adhesive interfaces. Leakage score at the dentin-CMR composite interface did not significantly differ between the two tested composites but was significantly lower for Group 3. In all groups, scores were significantly higher at the dentin interface than at the enamel interface. These results indicate that the performance of flowable and microhybrid resin composites, as indicated by marginal sealing ability, is comparable for CMR.

“…Adhesive systems allow new cavity designs to be used with composite materials because they do not require special retention forms like with amalgam restorations. In addition, deeper proximal boxes with limited or no enamel provided at the margins are more challenging clinically 29) . Therefore, maximum preservation of dental hard tissues and minimal invasive cavity designs should be selected to increase the longevity of the tooth 30) .…”

The aim of the study to evaluate the fracture resistance of a computer-aided design/computer-aided manufacturing (CAD/CAM) and three indirect composite materials for three different mesio-occluso-distal (MOD) inlay cavity designs. A total of 120 mandibular third molar were divided into three groups: (G1) non-proximal box, (G2) 2-mm proximal box, and (G3) 4-mm proximal box. Each cavity design received four composite materials: Estenia, Epricord (Kuraray, Japan), Tescera (Bisco, USA), and Cerasmart CAD/CAM blocks (GC, USA). The specimens were subjected to a compressive load at a crosshead speed of 1 mm/min. The data was analyzed using the two-way analysis of variance and Bonferroni post hoc test (p<0.05). Estenia exhibited significantly higher fracture strength than Epricord and Cerasmart in G1. In G2 and G3, there was no significant difference among the four materials. Using a non-proximal box design for the cavity can improve the fracture resistance of the inlay restoration.
