This study investigated the effect of surface treatments on the shear bond strength (SBS) between veneering porcelain and translucent zirconia (4Y-PSZ and 5Y-PSZ) compared with conventional zirconia (3Y-TZP). Methods: Forty-four specimens of each zirconia type (10.0 \u00d7 7.0 \u00d7 1.0 mm) were prepared and randomly assigned to four surface treatment groups: control (C), grinding with 150-grit silicon carbide paper (GR), airborne-particle abrasion with alumina particles (AB), and glazing (GL). Surface roughness (Ra) was measured for one specimen from each treatment group. Veneering porcelain cylinders (2.38 mm in diameter, 0.5 mm in thickness) were fabricated and bonded to the zirconia surfaces. SBS was evaluated using a universal testing machine (n = 10). Data were analyzed using two-way ANOVA and Tukey\u2019s HSD test (\u03b1 = 0.05). Results: The GL group exhibited the lowest Ra, whereas the AB group showed the highest Ra. Regarding zirconia type, 3Y-TZP demonstrated significantly higher SBS than 5Y-PSZ, while no significant differences were found between 3Y-TZP and 4Y-PSZ or between 4Y-PSZ and 5Y-PSZ. The AB and GL groups showed significantly higher SBS than the C group, whereas the GR group did not differ significantly from the C group. Conclusions: Airborne-particle abrasion and glazing effectively enhanced SBS across the zirconia types evaluated prior to veneering.<\/jats:p>","DOI":"10.3390\/dj14090586","type":"journal-article","created":{"date-parts":[[2026,9,11]],"date-time":"2026-09-11T09:09:40Z","timestamp":1789117780000},"page":"586","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Influence of Zirconia Type and Surface Treatment on the Shear Bond Strength Between Veneering Porcelain and Zirconia"],"prefix":"10.3390","volume":"14","author":[{"given":"Kamolporn","family":"Wattanasirmkit","sequence":"first","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dentistry, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"}]},{"given":"Karnkanith","family":"Hansomwong","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dentistry, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"data-curation","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-4968-2644","authenticated-orcid":false,"given":"Trakol","family":"Mekayarajjananonth","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dentistry, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"methodology","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"}]},{"given":"Sunphat","family":"Namano","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dentistry, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"methodology","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"}]},{"given":"Jaijam","family":"Suwanwela","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dentistry, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"methodology","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4778-0692","authenticated-orcid":false,"given":"Taksid","family":"Charasseangpaisarn","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, College of Dental Medicine, Rangsit University, 52\/347 Mueang-Ake, Lak Hok, Pathum Thani 12000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"252","DOI":"10.1016\/j.prosdent.2018.11.016","article-title":"Monolithic CAD-CAM lithium disilicate versus monolithic CAD-CAM zirconia for single implant-supported posterior crowns using a digital workflow: A 3-year cross-sectional retrospective study","volume":"123","author":"Passarelli","year":"2020","journal-title":"J.
