目的:分析铸瓷髓腔固位冠与铸瓷全冠的临床研究。方法:选择2014年10月至2016年6月收治疗的因牙髓炎或根尖周炎患牙,经完善根管治疗后1周,分成两组,铸瓷髓腔固位冠35例,为观察组;铸瓷全冠42例,为对照组,对比两组45颗牙经过治疗于3、6、12个月临床随访检查修复体边缘密合性、完整性、存留率、牙龈、食物嵌塞状况和颜色变化。结果:观察组的冠完整性94.3%(33/35)、存留率94.3%(33/35)、牙龈情况97.1%(34/35)、食物嵌塞状况85.7%(30/35)、颜色变化94.3%(33/35),观察组经过治疗3~12个月后边缘密合性、完整性、存留率、牙龈、食物嵌塞状况和颜色变化明显优于对照组,差异具有统计学意义(P<0.05)。结论:同一种材料不同修复形式,短期临床效果接近,铸瓷髓腔固位冠修复可以作为临床使用,但长期效果有待进一步研究。
Objective: To analyze the clinical research of casting porcelain crowns and cast crowns. Methods: The patients with pulpitis or periapical periodontitis who received treatment from October 2014 to June 2016 were divided into two groups one week after perfecting root canal treatment, and 35 cases were treated with cast porcelain medullary cavity fixation crown. As the observation group; porcelain crown 42 cases, as the control group, compared two groups of 45 teeth treated at 3, 6, 12 months of follow-up examination of prosthesis marginal adhesion, integrity, survival rate, gums, food Impaction and color changes. Results: The crown integrity of the observation group was 94.3% (33/35), the retention rate was 94.3% (33/35), the gingival condition was 97.1% (34/35), the food impaction was 85.7% (30/35) 94.3% (33/35). The margin adhesion, integrity, retention rate, gums, food impaction and color changes in the observation group after 3 ~ 12 months of treatment were significantly better than those in the control group P <0.05). Conclusion: The same material with different repair forms, short-term clinical effect close, cast porcelain marrow cavity retention crown can be used as a clinical, but the long-term results need further study.
