Gh. Clayton et al., THE EFFECT OF LUTING AGENTS ON THE RETENTION AND MARGINAL ADAPTATION OF THE CERAONE IMPLANT SYSTEM, The International journal of oral and maxillofacial implants, 12(5), 1997, pp. 660-665
In this study, various luting agents were evaluated to determine their
retentive strengths as they pertain to the CeraOne single-tooth impla
nt system. Ten samples of five different luting agents (zinc oxide-eug
enol, glass-ionomer cement, hybrid glass-ionomer cement, composite res
in, and zinc phosphate) were tested for retentive strength of the Cera
One gold cylinder to the CeraOne abutment. Under the conditions of the
experiment, zinc phosphate showed a mean retentive strength 164% grea
ter than that of glass-ionomer cement and 49% greater than that of com
posite resin cement. Scanning electron micrographs were taken to evalu
ate the effect of various luting agents on marginal opening. The measu
rements revealed that zinc phosphate had the greatest marginal opening
, although its mean value of 62 mu m is within clinically acceptable l
imits.
