Prosthetically driven digital workflow using a three- dimensional printed diagnostic overlay for crown lengthening: A case report

Crown lengthening in the anterior zone requires precise coordination between periodontal surgery and prosthetic rehabilitation to achieve predictable functional and aesthetic outcomes. Conventional workflows often require separate surgical guides and provisional restorations, increasing treatment complexity and chairside time. This clinical report describes a prosthetically driven digital workflow using a 3D -printed diagnostic overlay that served as both a surgical guide and a provisional restoration during crown lengthening.
