| description | Introduction: Marginal discrepancy severely affects the long
term success of All ceramic complete veneer crowns. The
precise role of resin luting agents influencing this phenomenon
needs to be explored further.
Aim: To estimate and compare the marginal discrepancy in
CAD/CAM processed All ceramic complete veneer crowns prior
and following luting with resin bonded luting agents.
Materials and Methods: Extracted human maxillary first
premolars were randomly allocated into four groups of 27
samples each Viz., Group I-Resin Modified Glass Ionomer
Cement (GIC) (RelyX), Group II-Bis-GMA based dual cure resin
cement (Variolink II), Group III-PMMA based resin cement
(Superbond), Group IV- Urethane Dimethacrylate resin cement
(Calibra). Following tooth preparation, CAD/CAM All ceramic
complete veneer crowns were fabricated and sectioned and
marginal discrepancy was evaluated using a scanning electron
microscope (TESCAN, Magnification power-1,00,000x) prior
and after luting with the experimental resin cements.
Results: The vertical and horizontal discrepancy before and after
cementation with Group I [270.08±103.10µm, 165.3±53.00µm
and 270.86±102.70µm, 166.62±54.96µm respectively]; Group
II [254.21±79.20µm, 117.75±24.29µm and 234.81±79µm,
116.89±18.22µm respectively]; Group III [272.47±86.25µm,
142.08±50.83µm and 251.82±62.69µm, 136.07±44.95µm
respectively]; Group IV were [260.28±64.81µm, 116.98±17.71µm
and 233.08±69.44µm, 116.58±21.13µm respectively]. ANOVA
inferred a statistically significant difference between the four
test specimen with regards to vertical and horizontal marginal
discrepancy after cementation (F=9.092, p<0.001), (F=10.97,
p<0.001). Tukey HSD Post-hoc test observed significant
differences in vertical and horizontal marginal discrepancies
between the resin modified glass ionomer and resin cements
(p<0.05).
Conclusion: Resin cements exhibited a greater reduction in
the marginal discrepancy than the resin modified glass ionomer
following luting in All ceramic complete veneer crowns. Hence
resin cements are more preferable to GIC for luting All ceramic
complete veneer crowns. |
