Summary

Deep margin elevation (DME) is a non-invasive restorative technique to relocate the deep cervical margin to a supragingival position using resin composite. This retrospective multicenter practice-based study will assess the long-term clinical performance and periodontal health of teeth restored with CAD-CAM crowns with or without DME. Patients who will receive CAD-CAM lithium disilicate (LD) crowns with or without DME between 2013 and 2023 at multiple private practices will be included. When indicated, DME will be performed using resin-based restoration. Clinical assessment of the crowns and supporting periodontal structures will be performed following the modified United States Public Health Service (USPHS) criteria. Intra-oral photographs, periapical and bitewing radiographs will be taken for further assessment by three evaluators. Kaplan Meier survival analyses will be performed.
