This study aimed to investigate the micro-shear bond strength (\u03bcSBS) of stereolithography (SLA)- and digital light processing (DLP)-fabricated zirconia\u2013resin cement-composite resin bonding specimens. Rectangular zirconia specimens (10 \u00d7 5 \u00d7 5 mm3) were fabricated by SLA, DLP, and computer numerical control (CNC) milling technologies. The surface roughness (Ra) of zirconia was measured after air abrasion. A composite resin cylinder (5 mm in height and 1 mm in diameter) was added to each zirconia substrate for the \u03bcSBS test. The failure mode images were obtained using a scanning electron microscope. The adhesive, cohesive, and mixed failure patterns were analyzed. The Ra and \u03bcSBS values were statistically analyzed with one-way ANOVA followed by S-N-K post hoc comparisons (a = 0.05). The Ra of SLA (1.05 \u00b1 0.03 \u03bcm) and DLP (1.02 \u00b1 0.03 \u03bcm) zirconia after air-abrasion were significantly higher than that of CNC (0.91 \u00b1 0.02 \u03bcm) (p &lt; 0.001). The SLA (23.37 \u00b1 4.66 MPa) and DLP (23.24 \u00b1 3.7 MPa) groups exhibited similar \u03bcSBS values for the bonding specimens to those of the CNC group (21.13 \u00b1 3.48 MPa) (p = 0.237), indicating that the bond strength of the zirconia\u2013resin cement-composite resin assembly for SLA and DLP zirconia was comparable to that for CNC zirconia.<\/jats:p>","DOI":"10.3390\/polym18182305","type":"journal-article","created":{"date-parts":[[2026,9,21]],"date-time":"2026-09-21T11:05:53Z","timestamp":1789988753000},"page":"2305","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Adhesion of Composite Resin to Additively Manufactured Zirconia Using a Self-Adhesive Resin Cement: Evaluation of Micro-Shear Bond Strength"],"prefix":"10.3390","volume":"18","author":[{"given":"Yue","family":"Zhu","sequence":"first","affiliation":[{"name":"Department of Prosthodontics, Shanghai Ninth People\u2019s Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai 200011, China"},{"name":"College of Stomatology, Shanghai Jiao Tong University, Shanghai 200011, China"},{"name":"National Center for Stomatology, Shanghai 200011, China"},{"name":"National Clinical Research Center for Oral Diseases, Shanghai 200011, China"},{"name":"Shanghai Key Laboratory of Stomatology, Shanghai 200011, China"},{"name":"Shanghai Research Institute of Stomatology, Shanghai 200011, China"},{"name":"Department of Stomatology, Shanghai Putuo Central Hospital, Shanghai 200062, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"software","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"}]},{"given":"Chao","family":"Qian","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Shanghai Ninth People\u2019s Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai 200011, China"},{"name":"College of Stomatology, Shanghai Jiao Tong University, Shanghai 200011, China"},{"name":"National Center for Stomatology, Shanghai 200011, China"},{"name":"National Clinical Research Center for Oral Diseases, Shanghai 200011, China"},{"name":"Shanghai Key Laboratory of Stomatology, Shanghai 200011, China"},{"name":"Shanghai Research Institute of Stomatology, Shanghai 200011, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"365","DOI":"10.1016\/j.sdentj.2020.05.004","article-title":"All-ceramic restorations: A review of the literature","volume":"32","author":"Warreth","year":"2020","journal-title":"Saudi Dent.
