Two self-adhesive resin cements,
G-CEM LinkAce (GC Corporation, Tokyo, Japan) and
RelyX U200 (3M ESPE, St. Paul, MN, USA), were used for the SBS test. The information on these cements is shown in
Table 2. All of the disc-shaped Y-TZP specimens were distributed 40 per surface treatment group. For each group, half of the specimens were bonded with
G-CEM LinkAce resin cylinder, and the rest were bonded with
RelyX U200 resin cylinder. Each resin cylinder was made in a uniform size by injecting self-adhesive resin cement into a ready-made plastic jig (Ultradent Jig, Ultradent Products Inc., South Jordan, UT, USA) with a diameter of 2.38 mm and a height of 3 mm, then light polymerized at 1000–1200 mW/cm
2 for 20 seconds in three directions with an LED curing light (
Elipar™ DeepCure-L, 3M ESPE, St. Paul, MN, USA). At this time, a custom-made positioning stand was used for the Y-TZP specimens embedded in acrylic resin. This stand was manufactured with a CAD program (
Tinkercad, Autodesk Inc., San Francisco, CA, USA) and a 3D printer (DIO PROBO, DIO inc., Busan, Korea) (
