Advances in adhesive technology and esthetic dental materials have permitted clinicians to perform conservative preparation of the dentition for onlay restorations. Indirect resin onlays are a great alternative to dental crowns for reestablishment the function and esthetic in teeth with great destruction. Key messages Indirect resin onlay is economical solution to satisfy the function and esthetic requirements of these patients. The cementation with self-adhesive resin cement is practice, fast and reduces the postoperative sensitivity.

This study investigated the physicochemical properties of the new formulation of the glass ionomer cements through hardness test and degree of conversion by infrared spectroscopy (FT-IR). Forty specimens (n = 40) were made in a metallic mold (4 mm diameter x 2 mm thickness) with two resin-modified glass ionomer cements, Vitrebond TM and Vitrebond TM Plus (3M/ ESPE). Each specimen was light cured with blue LED with power density of 500 mW/cm 2 during 30 s. Immediately after light curing, 24h, 48h and 7 days the hardness and degree of conversion was determined. The Vickers hardness was performed by the MMT-3 microhardness tester using load of 50 gm force for 30 seconds. For degree of conversion, the specimens were pulverized, pressed with KBr and analyzed with FT-IR (Nexus 470). The statistical analysis of the data by ANOVA showed that the Vitrebond TM and Vitrebond TM Plus were no difference significant between the same storage times (p > 0.05). Plus. The correlation between hardness and degree of conversion was no evidence in this study.
