Deep Marginal Elevation; a retrospective clinical study
Objectives: Deep marginal elevation (DME) is a convenient restorative option that allows us to avoid lengthy and expensive procedures when restoring teeth with deep subgingival proximal margins. However, concerns have been raised about its suitability, influence on periodontal tissues and long-term outcome. This restrospective study aimed to assess the short-term restorative, periodontal and patient-reported outcome of DME.
Methods: Thirty teeth restored with DME and indirect adhesive restorations were followed up for a mean of 23.9 months. Clinical and radiographic examination assessed the adaptation of the direct and indirect restorations, the presence of recurrent caries or discoloration, and the periodontal and periapical health. Patient satisfaction with the provided treatment was assessed on a visual analogue scale.
Results: The overall success rate was 96.6%. One tooth became symptomatic 38 months following DME and showed evidence of apical pathology. No caries, discoloration or periodontal disease was detected in the rest of the teeth. DME had no detrimental effect on the gingival/ periodontal health or plaque accumulation compared with the non-DME sites (X2: 5.23, p= 0.073 and X2: 0.313. p= 0.86 respectively) . All patients were satisfied with DME and reported that they would choose it again over surgical crown lengthening or orthodontic extrusion.
Conclusions: DME is a promising restorative option on the short/medium term. More robust evidence from randomized controlled trials with long-term follow-up is needed to confirm its suitability.
