Abstract:
Objective To estimate the clinical effect of cutting titanium inlay crown in the restoration of short cracked molar. Methods Sixty-four short coronal cracked teeth were randomly divided into group A and group B. Group A were treated by crown. Group B were treated by titanium inlay crown. The curative effect was evaluated every year and lasted 2 years. Results One year after the repair, there was no significant difference in the achievement ratio between two groups (93.8%vs 100%,χ2=2.064, P>0.05). Two years after the repair, the success rate was significantly higher in group B (96.9%) than that of group A (68.8%,χ2=8.892, P<0.01). The failed cases of group A were treated by cutting titanium inlay crown, showing good retention. Conclusion The retention of a short cracked molar can be improved by means of cutting titanium inlay crowns.
