“…However, after 24 months surface gloss deteriorated but occlusal wear continued to be similar to that of enamel. 20 In this study, there was no appreciable difference in the surface gloss between the two types of onlays with 91.6% (55/60) scored as alpha after 5 years…”

“…There are very limited clinical studies on resilient ceramic materials since they are relatively new materials. One clinical study on Lava Ultimate included 42 onlays fabricated with the CEREC system and adhesively delivered with a dual cured resin cement (Variolink II/Ivoclar) for 30 patients . Two onlays debonded within the first 12 months requiring replacement resulting in a success rate of 95.0%.…”

“…for 30 patients. 20 Two onlays debonded within the first 12 months requiring replacement resulting in a success rate of 95.0%. There were two fractured onlays and one additional debonded onlay requiring replacement after 2 years of clinical function resulting in a cumulative success rate of 85.7%.…”

“…A recent study of Lava Ultimate partial coverage crowns reported that the surface gloss was stable with minimal surface abrasion after 12 months. However, after 24 months surface gloss deteriorated but occlusal wear continued to be similar to that of enamel . In this study, there was no appreciable difference in the surface gloss between the two types of onlays with 91.6% (55/60) scored as alpha after 5 years (Figures A‐D and A‐D).…”

Objectives This investigation was a longitudinal, randomized clinical trial to measure the clinical performance of a nano‐ceramic material (Lava Ultimate/3M) for chairside Computer Assisted Design/Computer Assisted Machining (CAD/CAM) fabricated restorations. Materials and Methods One hundred and twenty chairside CAD/CAM onlays were restored with a CEREC system randomly assigned to 60 leucite‐reinforced ceramic (IPS EmpressCAD/Ivoclar Vivadent AGBendererstrasse 2FL‐9494 SchaanLiechtenstein) onlays and 60 nano‐ceramic (Lava Ultimate/3M) onlays. Equal groups of onlays were cemented using a self‐etch and a total etch adhesive resin cement. The onlays were recalled for a period of 5 years. Results At 1 week postoperatively, 10% of the onlays cemented with both the self‐etch and total etch adhesive resin cements were reported as slightly sensitive. However, all patients were asymptomatic by the 4th week without treatment. Four leucite‐reinforced onlays and one nano‐ceramic onlay fractured and required replacement. Conclusions Adhesive retention with a self‐etch or total etch cementation technique resulted in a similar clinical outcome with no reported debonds. The nano‐ceramic onlays had a lower incidence of fracture compared to the leucite‐reinforced ceramic onlays with both having a very low risk of fracture. Nano‐ceramic onlays performed equally as well as glass ceramic onlays over 5 years of clinical service. Clinical Significance Ceramic materials have been a mainstay for chairside CAD/CAM restorations for the past 30 years and a new category of resilient ceramics with a resin matrix has been introduced reported to offer ceramic‐like durability and esthetics with resin‐like efficiency in handling. There are no long‐term clinical studies on the performance of these materials. This is a 5‐year randomized clinical trial on the performance of nano‐ceramic onlays.

Objective The aim of this study was to evaluate the 2‐year clinical performance of computer‐aided design/computer‐aided manufacturing (CAD/CAM) resin composite inlay restorations in comparison with direct resin composite restorations. Materials and methods In 44 patients, 120 class II (mesio‐occlusal/disto‐occlusal) cavities were randomly assigned into two groups; CAD/CAM resin composite inlay group (Lava Ultimate), direct resin composite group (Clearfil Majesty Posterior). Clinical evaluations were performed after 1 week, 6 months, 1 year, and 2 years according to the FDI criteria. The data were analyzed using Friedman's ANOVA and Mann‐Whitney U tests (α = .05). Results In 41 patients, 114 restorations were evaluated at the second year (recall rate 93.2%). All restorations were ideal or clinically acceptable. At the first year, considering all criteria, there were no statistically significant differences between the groups. However, there was a significant difference in terms of surface luster at second year, in favor of inlay restorations (P = .015). The marginal staining of resin composites increased after 2 years (P = .046), but there was no significant difference between the groups. Conclusions Except the surface luster, 2‐year clinical performance of CAD/CAM resin composite inlay restorations was found similar to direct resin composite restorations according to FDI criteria Clinical Significance The clinical performance of CAD/CAM resin composite inlays was acceptable in class II cavities subsequent to 2‐year evaluation.

Clinical Evaluation of Indirect Particle‐Filled Composite Resin CAD/CAM Partial Crowns after 24 Months

Abstract: This study demonstrates particle-filled composite resin CAD/CAM restorations having a clinical success rate of 85.7% after 24 months. Adhesive bonding procedures need to be ensured carefully. A longer clinical evaluation period is necessary to draw further conclusions.
