Although in\u00a0vitro studies have demonstrated that three\u2011dimensionally (3D)\u2011printed textures on zirconia cores can strengthen the zirconia\u2013porcelain bond and thereby may reduce chipping incidence of PVZCs, their clinical performance remains to be verified. The purpose of this randomized clinical trial was to preliminarily investigate the influence of 3D\u2010printed textures of zirconia cores on the clinical performance of PVZCs, particularly the influence on esthetic properties.<\/jats:p>\n <\/jats:sec>\n \n Materials and Methods<\/jats:title>\n \n Sixteen participants requiring PVZCs for anterior tooth defects to mask severely discolored abutment teeth or metal post\u2010and\u2010core restorations were randomly allocated to two groups (eight participants per group). All zirconia cores were 3D\u2010printed using advanced customized jetting (ACJ) technology and veneered with feldspathic porcelain. Cores in the experimental group were fabricated with 200\u00a0\u00b5m high textures on the veneering surface, whereas cores in the control group were fabricated smooth; airborne\u2010particle abrasion (APA) was applied to both surfaces of the control cores and to the internal surface only of the textured cores. Color matching against target teeth was assessed using a spectrophotometer. Clinical evaluations were performed at baseline and at the 1\u2010, 3\u2010, and 6\u2010month follow\u2010ups and included assessment of color match, translucency, chipping\/fracture, and participant satisfaction. Color differences (\u0394\n E<\/jats:italic>\n 00<\/jats:sub>\n ) were compared between groups by using independent\u2010samples\n t<\/jats:italic>\n tests, and the repeatedly measured clinical ratings were analyzed by using linear mixed\u2010effects models (\n \u03b1<\/jats:italic>\n = 0.05).\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n No statistically significant differences in \u0394\n E<\/jats:italic>\n 00<\/jats:sub>\n were found between the groups in any evaluated region, and no significant effects of group, time, or their interaction were found for color match, translucency, or participant satisfaction (\n p<\/jats:italic>\n > 0.05). No chipping or fracture occurred in either group, and participant satisfaction remained high in both groups. The mean \u0394\n E<\/jats:italic>\n 00<\/jats:sub>\n values ranged from 2.52 to 3.54 across regions and groups.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Over a 6\u2010month clinical evaluation, PVZCs with 3D\u2010printed textured cores showed esthetic and clinical performance comparable with that of air\u2010abraded nontextured cores. These findings are preliminary and require confirmation in studies with larger samples and longer follow\u2010up.<\/jats:p>\n
