Objectives This prospective controlled clinical trial aimed to compare periodontal parameters of proximal deep-margin-elevation (DME) restoration margins with supragingival/equigingival restoration margins (control) on the opposite proximal surface of the same tooth. Materials and methods Subgingival one-sided proximal defects (mesial or distal) on (pre-)molars were restored with composite DME and CAD/CAM-manufactured lithium disilicate ceramic partial-coverage restorations. Periodontal parameters (bleeding on probing (BOP), periodontal probing depths (PPD), plaque index (PI)) were recorded after insertion of the ceramic restoration (baseline) and at 1-year recall visit and compared between DME and control on the same tooth (Fisher’s exact test and Wilcoxon signed rank test, p < 0.05). Results Sixty-eight patients with 77 restorations were included. At baseline, periodontal parameters did not differ between DME and control. Sixty-two restorations could be examined after 1 year. BOP was significantly increased for DME (padj. = 0.003), but not for control (padj. = 0.714). Surfaces with DME showed a significantly higher proportion of BOP than control surfaces (DME: 45 restorations (73.8%), control: 27 restorations (44.3%); padj. = 0.005). PI increased significantly on all tooth surfaces (padj.<0.001), but did not differ between DME and control side (padj. = 0.162). Probing depths did not differ between baseline and follow-up (DME: padj. = 0.199, control: padj. = 0.116). Two restorations were replaced due to a ceramic fracture and secondary caries. Conclusion Proximal DME is associated with increased gingival inflammation compared to supragingival or equigingival restoration margins. Clinical relevance DME is a promising treatment approach for indirect restoration of teeth with deep proximal defects, but gingival inflammation should be expected.

ObjectiveThis article puts forward consensus recommendations from PROSEC North America regarding single indirect restorations made from ceramic and nonmetallic biomaterials in posterior teeth.OverviewThe consensus process involved a multidisciplinary panel and three consensus workshops. A systematic literature review was conducted across five databases to gather evidence. The recommendations, informed by findings from systematic reviews and formulated based on a two‐phase e‐Delphi survey, emphasize a comprehensive treatment strategy that includes noninvasive measures alongside restorative interventions for managing dental caries and tooth wear. The recommendations advocate for selecting between direct and indirect restorations on a case‐by‐case basis, favoring inlays and onlays over crowns to align with minimally invasive dentistry principles. The recommendations highlight the critical role of selecting restorative biomaterials based on clinical performance, esthetic properties, and adherence to manufacturer guidelines. They emphasize the importance of precision in restorative procedures, including tooth preparation, impression taking, contamination control, and luting. Regular follow‐up and maintenance tailored to individual patient needs are crucial for the longevity of ceramic and nonmetallic restorations.ConclusionsThese PROSEC recommendations provide a framework for dental practitioners to deliver high‐quality restorative care, advocating for personalized treatment planning and minimally invasive approaches to optimize oral health outcomes.Clinical SignificanceThe PROSEC North America recommendations highlight the importance of minimally invasive techniques in posterior tooth restorations using ceramic and non‐metallic biomaterials. These principles prioritize tooth structure conservation and personalized treatment planning, essential for enhancing clinical outcomes and long‐term oral health.
