上颌前牙一次法根管治疗术后Ceramage聚合瓷冠修复的临床观察

目的探讨上颌前牙根管治疗术后聚瓷冠修复的临床效果。方法选择口腔门诊患者145例294颗牙，一次法根管治疗术后。玻璃纤维桩树脂核全冠修复：实验组73例147颗牙Ceramage聚合瓷冠修复，对照组72例147颗牙金属烤瓷冠修复。观察其修复体的色泽、边缘适合性、耐磨性以及龈染、患者的满意度。结果Ceramage聚合瓷冠修复73例，失败2例，成功率为97．3％；金属烤瓷冠修复72例，失败10例，成功率为86．1％。实验组在色泽、边缘适合性、有无龈染、患者的满意度上明显优于对照组。结论一次法根管治疗术后Ceramage聚合瓷冠修复上颌前牙，具有广阔的应用前景。

Clinical observation of ceramage polymerization porcelain crown restoration after one-time root canal therapy on maxillary anterior teeth

Objective To discuss the clinical effect of polymerization porcelain crown restoration after root canal therapy on maxillary anterior teeth.Methods By selecting 294 teeth of 145 stomatological outpatients as examples,glass fiber post and resin core crown restoration was applied after one-time root canal therapy: Ceramage polymerization porcelain crown restoration for the experiment group of 147 teeth of 73 patients and metal-fused porcelain crown restoration for the control group of 147 teeth of 72 patients in order to observe the color,marginal adaptation,wear resistance and gingival staining restorations and patient satisfaction.Results For the Ceramage polymerization porcelain crown restoration: 2 cases were failed with a success rate of 97.3%;and for the metal-fused porcelain crown restoration: 10 cases were failed with a success rate of 86.1%.The color,marginal adaptation,wear resistance and gingival staining restorations and patient satisfaction of the experiment group were obviously superior to those of the control group.Conclusion the polymerization porcelain crown restoration after one-time root canal therapy on maxillary anterior teeth is of a broad application prospect.
