Abstract:: Abstract: Objective To investigate the short-term clinical effect of domestic zirconia crowns with full anatomical morphology
in repairing molar defects. Methods 80 patients with molar defect were randomly divided into two groups. Group A was
repaired with domestic zirconia crowns with full anatomical morphology, while group B was repaired with imported. The
effects such as prosthesis integrity, marginal fitness, gingival inflammation, prosthesis shape and color were recorded at 3, 6 and
12 months after restoration, and the subjective satisfaction of the patients was analyzed. Results During the observation period,
one patient with mild gingivitis was detected at 6 months after restoration in group A. Two groups of prostheses showed that a
small part of occlusal staining was abraded to varying degrees, resulting in slight color difference with adjacent teeth at 6 and
12 months after restoration. There was significant difference in price between the two groups (P ＜0.05). Conclusion The shortterm
observation of domestic zirconium zirconia crowns with full anatomical morphology has a good effect in repairing molar
defects. It can be used clinically according to the specific conditions.
