| Summary: | Objective To investigate the clinical use of glass ceramic onlay in the restoration of the non⁃vital posteri⁃
or teeth with computer aided design and computer ⁃aided manufacturing technique (CAD/CAM). Methods 70 patients
with 75 teeth of residual crown were selected and restored with CAD/CAM glass⁃ceramic onlay after completely root canal
therapy. Marginal adaptation, anatomic form, adjacent relation, contour appearance, color match were checked in 12 ⁃
month follow⁃up. Results Marginal adaptation, anatomic form, adjacent relation, contour appearance, color match of 73
teeth were satisfactory and 2 cases was excluded because of lost to follow⁃up. There were no significant differences in the
number of cases which met clinical criterion A or B between immediate restoration and 12⁃month follow⁃up (P > 0.05),
and more than 95% of cases met clinical criterion A. Conclusion The CAD/CAM glass⁃ceramic onlay in the restoration
of non⁃vital posterior teeth can provide better effect of retention and esthetics in a short term observation of 12 months. |
