According to this review , the 3-step adhesive systems were the best performing and still are the gold st and ard for the cementing of indirect restorations .
In addition , it can be concluded that self-etched adhesive systems reduce the time spent in clinical practice , however at the interface level they behave as permeable membranes more susceptible to degradation
New technologies are changing the therapeutical options to do indirect restorations and new adhesive systems are continuously introduced to be used by clinicians .
Different interactions between restorations , adhesive systems components , enamel and dentin require having criteria based on the selection of the adhesive system , ensuring the longevity of the restorations and the preservation of the biological remnant .
The adhesion force to the dental tissue is one of the indicatives of the behavior of the adhesive systems and influences the behavior of the treatments with direct and indirect restorations .
The objective of this search was to find the adhesive systems with the best results in terms of the adhesion strength of indirect restorations  on the dental tissues .
A practice-based research network on the survival of ceramic inlay/onlay restorations.
OBJECTIVE To evaluate prospect ively the longevity of  ceramic inlay/onlay restorations  placed in a web-based practice -based research network and to investigate risk factors associated with restoration failures . MATERIAL S AND METHODS Data were collected by a practice -based research network called Ceramic Success Analysis ( CSA ) . 5791 inlay/onlay ceramic restorations were placed in 5523 patients by 167 dentists between 1994 and 2014 in their dental practice s. For each restoration specific information related to the tooth , procedures and material s used were recorded . Annual failure rates ( AFRs ) were calculated and variables associated with failure were assessed by a multivariate Cox-regression analysis with shared frailty . RESULTS The mean observation time was 3 years ( maximum 15 years ) of clinical service , and AFRs at 3 and 10 years follow up were calculated as 1.0 % and 1.6 % . Restorations with cervical outline in dentin showed a 78 % higher risk for failure compared to restorations with margins in enamel . The presence of a liner or base of glass-ionomer cement result ed in a risk for failure twice as large as that of restorations without liner or base material . Restorations performed with simplified adhesive systems ( 2-step etch- and -rinse and 1-step self-etch ) presented a risk of failure 142 % higher than restorations performed with adhesives with bonding resin as a separate step ( 3-step etch- and -rinse and 2-step self-etch ) . 220 failures were recorded and the most predominant reason for failure was fracture of the restoration or tooth ( 44.5 % ) . CONCLUSIONS Ceramic inlay/onlay restorations made from several glass ceramic material s and applied by a large number of dentists showed a good survival . Deep cervical cavity outline , presence of a glass ionomer lining cement , and use of simplified adhesive systems were risk factors for survival
