A Novel Volumetric Analysis Using CAD/CAM Scanners in Gingival Recession Treatment

Aim: In this ramdomised clinical trial (RCT), the aim was to compare clinical periodontal data of subepithelial connective tissue graft (SCTG) group and SCGT+enamel matrix derivatives (EMD) group in terms of gained gingiva volume (GGV) and gained gingiva surface area (GGSA) by scanners of computer-aided design/computer-aided manufacturing (CAD/CAM) devices. Materials and Methods: A total of 35 Miller class I-II gingival recession defects were involved in this study (n=17 in SCTG group, n=18 in SCTG+EMD group). In addition to periodontal clinical parameters, three dimensional (3D) images were recorded using CAD/CAM system before the treatment, at the 1st month and at the 6th months after the treatment. The images were superimposed using softwares and GGV, GGSA were calculated.
