Abstract

Objective

To compare the clinical effects of polymer ceramic onlay and all ceramic crown in short crown molars.

Methods

45 cases of polymer ceramic onlay and 45 cases of Zirconium dioxide all ceramic crowns which repaired the short crowm molars after root canal therapy were compared clinically from the aspects of beauty of restoration, fracture and dislodgement, marginal adaptation and the preservation of abutment teeth.

Results

One polymer ceramic onlay had fall out form the teeth after half year, while the all ceramic crowns have been 8 cases after 6~12 months. There were significant differences in fracture and dislodgement between the two groups (χ2=4.44, P<0.05).

Conclusion

Polymer ceramic onlay has good clinical effects in the restoration of short crown molars.
