“…Currently available data do not provide conclusive evidence on which adhesive strategy is most appropriate for DME. A recent systematic review also found no clear effect of different bonding protocols and types of adhesives on marginal adaptation of RBC restorations in class II cavities extending beyond the CEJ 51 . This suggests that one may choose the adhesive strategy for DME according to one's personal preference.…”

“…51 DME restorations with adequate marginal adaptation and favorable behavior under cycling loading can be made with conventional RBC, flowable RBC, and bulk fill RBC of different viscosities, which is why dental practitioners may choose any of these RBC materials to restore deep proximal boxes. 51,52 A clinical case in which the DME technique was used to treat a mandibular molar with a bonded ceramic onlay is shown in Figures…”

However, when an etch-and-rinse or selective enamel etch approach is applied, over-etching or inadvertent etching of dentin should be avoided.…”

Objective: Deep margin elevation (DME) is a treatment approach to relocate the cervical margin of teeth with subgingival defects to a supragingival position with a direct restoration to facilitate rubber dam isolation, impression taking, and bonding of indirect restorations. This article provides an overview of the current scientific evidence on DME and future directions for research. Overview:The review included 38 studies on DME, most conducted in vitro. These studies indicate that DME has no detrimental effect on the fracture resistance of restored teeth. Evidence on the impact of DME on marginal quality is conflicting, but most in vitro studies observed no negative effect. Clinical studies, most comprising small patient cohorts, demonstrated favorable restorative outcomes and suggest that DME restorations made with scrupulous care are compatible with periodontal health. Bleeding on probing may occur more frequently at sites with DME, though evidence on this is not unequivocal.Conclusions: Current evidence, based largely on laboratory studies and limited clinical data, supports DME as a viable approach to restore teeth with localized subgingival defects. However, further clinical studies with long-term follow-ups are required to provide corroborative evidence.Clinical Significance: Current evidence suggests that DME is a viable approach to restore teeth with localized subgingival defects as a possible alternative to surgical crown lengthening. Proper working field isolation, meticulous care in the bonding and buildup procedure, and biofilm removal through patient-performed oral hygiene and professional maintenance care are crucial. As scant clinical trial-based evidence is available today, further research is needed to evaluate the long-term performance of DME restorations and their impact on periodontal health.

“…The materials used for the marginal elevation technique must provide an adequate interface with the tooth to be restored to ensure a correct and lasting seal. Resin-based materials are ideal for this task, which does not mean that other materials have not been studied for this application, such as vitreous ionomer; although the results show a clear advantage of resin materials in critical aspects such as marginal micro leakage rates [16][17][18] . Regarding the ideal adhesive systems to perform marginal elevation, it has been found that those of the 6th generation (2-component self-adhesives) provide the best results in terms of bond strength and micro leakage [19] ; although those of the 4th generation (2-component total etch) provide excellent clinical results, they have the difficulty that under-or overetch on dentin can compromise the adhesive interface.…”

Introduction: Deep margin elevation is a technique that allows reestablishing the location of restorative margins to a coronal position, without the need for surgery using adhesive materials. Objective: To review the literature on the deep margin elevation technique, materials used, advantages compared to crown lengthening and limitations. Methodology: A review was carried out in the databases Scopus, PubMed and Google scholar with the keywords "DME", "deep margin", "margin repositioning", "cervical margin repositioning", "subgingival margin". Results: The correct isolation, placement of matrices, adhesive technique and polishing are the basis of this technique; and in turn are facilitated using magnification. The most used materials are resin-based, the ideal adhesives are 2-step self-etching and although traditional composite resins are the most used, high-loading fluids show promising results. The absence of a recovery period and the fact that there is no affection of the periodontium if properly executed are its main advantages. Although this technique simplifies the restorative process, it is important to be aware of limitations such as a minimum distance of 2mm from the crest for its execution, the possibility of isolating and placing matrix, as well as the use of high quality materials. Conclusion: Knowing and respecting the limitations of this technique, it is possible to manage lesions that before its adoption required surgical management without the need for a healing period and the option to take the impression or rehabilitate immediately.

“…Nevertheless, in the lamination technique one of the decisive aspects for longevity of these restoration is a consistent bonding between the GIC and the resin composite restorative. Several investigations presented that the failure of such restorations was due inability to achieve proper bond between glass ionomer and composite resin [7] . Such bond is micromechanical intermediated by the adhesive bonding system.…”

Objective: To evaluate the influence of the application of various adhesives on the strength of the bonding established amongst resin-modified glass-ionomer cement (RMGIC) and resin composite restoration (RBC).Materials and method: Twenty discs were made-up with (RMGIC) and divided into four groups (n = 5) based on the adhesive resin system applied. Cylinders of resin composite were bonded to the RMGI discs utilizing different adhesive resin systems in the first three groups. While the fourth group was used as a control receiving no adhesive resin treatment. Microshear bond strength was measured and the data was registered with computer software in MPa. Results:The results revealed that applying different adhesive resin systems statistically significantly increased the bond strength between the tested materials. Conclusion:Microshear bond strength of (RMGIC) to resin composite improved considerably using different adhesive resin systems. The outcomes vary depending upon the type of adhesive resin system utilized.
