This study aims to investigate the mechanical properties, composition and surface preparation for adhesive bonding of the recently introduced zirconia-reinforced lithium silicate (ZLS) glass-ceramic. One single block of ZLS was used to prepare the specimens (n=14). The fracture toughness (Ft) and the Vickers hardness (HV) were measured on specimens partially crystallized (PCs) (n=4) and fully crystallized (FCs) at 840°C for 8 min (n=4). The surface treatment was done using hydrofluoric-acid gel (HF) at different concentrations and times of action on FCs specimens (n=4). SEM-EDX was used to test elemental composition and crystalline phases (n=2). The new ZLS glass-ceramic showed significantly higher values of HV and Ft for FCs, PCs showed a brittle behavior. The surface etching should be made using HF at 4.9% for 20 s.

“…Lithium disilicate glass ceramics have improved physical properties compared to other glass ceramics. The IPS e. max glass ceramic has a flexural strength of 360-500 MPa, which is more than twice greater than that of other glass ceramic monolithic materials (Fasbinder et al, 2010).…”

“…Lithium disilicate and Zirconia ceramics: Lithium disilicate (2SiO 2 -Li 2 O), such as IPS e. max (Ivoclar Vivadent) which is available as an ingot and block, can be processed using the lost-wax hot pressing techniques (ingot, IPS e. max press) or state-of-the-art computeraided design/computer-aided manufacturing (CAD/CAM) milling procedure (block, IPS e. max CAD) (Fasbinder et al, 2010). It can be used for anterior/posterior crowns, inlays/onlays, veneers, implants and fixed partial denture prosthesis frameworks The pre-crystallized blocks or ingots are milled to the desired form by CAD/CAM or pressing techniques and the final crystallization occurred at 850°C (CAD/CAM) or 920°C (Pressing) under vacuum (Fasbinder et al, 2010;Conrad et al, 2007).…”

Problem statement: All-ceramic materials, especially silica-based lithium disilicate and nonsilicate-based Zirconia, have become a topic of interest in the field of dentistry. It is still difficult to achieve a strong and durable resin-ceramic adhesion, especially resin-Zirconia bonding. Approach: The article reviews the current literature published in the past 5 years, focusing on the latest resin bonding techniques (including surface treatment, priming and cementation) for dental all-ceramic materials, especially Zirconia and lithium disilicate ceramics. A search of dental literature from PubMed and MEDLINE databases was conducted and the key words included Zirconia, lithium disilicate and bond. Titles and abstracts of the articles listed from search results were reviewed and evaluated for appropriateness. Results: The literature demonstrates that a variety of surface roughness, priming and cementation methods are available for improving resin-ceramic bonding. Conclusion: Available data suggest that the preferred bonding methods for silica-based ceramics are hydrofluoric acid-etching and subsequent silent treatments. The preferred protocol for Zirconia-resin bonding is the combination of surface roughness such as air-abrasion and treatment with a phosphate-containing Zirconia primer followed by cementation with a non-phosphate-containing resin cement.

The purpose of the present study is to evaluate the fracture resistance of endodontically treated maxillary premolars restored using CAD/CAM onlays or crowns and luted with two types of resin cement. Forty all-ceramic crowns and twenty onlays were fabricated on maxillary premolars using the Cerec 3 system (n=10). The abutments were randomly subjected to two different procedures: Endodontic treatment was performed on forty teeth restored through a mesio-occlusal-distal (MOD) cavity preparation with composite resin fillings; twenty teeth without endodontic treatment served as control. In endodontically treated teeth restored using IPS e.max CAD crowns or onlays, the fracture loads were lower than those of the control. Endodontic treatment of teeth restored using CAD/ CAM crowns does not impair the fracture load but shows more severe fractures than teeth restored using CAD/CAM onlays. This suggests that a CAD/CAM onlay might be an effective method for the restoration of endodontically treated premolars with MOD cavity defect.
