Abstract: Objective This study aims tocompare the clinical effects of computer-aided design and computer-aided manufacturing(CAD/CAM) zirconia ceramic post and glass fiber post in defected upper anterior teeth restoration. Methods Forty upper anterior teeth in patients aged from 18–55 years old, who had been given complete root canal treatment, were randomly selected. Twenty zirconia ceramic posts and 20 glass fiber posts were included in each group. All teeth were restored with CAD/CAM zirconia all-ceramic crowns. The restorations, tooth roots, and periodontal health were evaluated after two years of restoration. Results In the ceramic post group, one case had porcelain breakage, one had post-core fracture, and one had gingival inflammation. In the fiber post group, one case had a loosened post, one had post-core fracture, and two cases had gingival inflammation. Neither fracture of the roots nor periapical pathology was observed in the two groups. The clinical effects of restoration had no significant difference(P>0.05). Conclusion No significant difference was found in the stability, resistance to root fracture, and capacity of controlling periodontal and dental pulp diseases between CAD/CAM zirconia ceramic post and glass fiber post. Both approaches can achieve good clinical effects.
