高嵌体修复无髓磨牙牙体缺损的观察

The Observation of the High Volume of Inlay in the Restoration of the Tooth Defect of the Teeth With No Teeth

目的评价金属材料制作高嵌体修复根管治疗后磨牙的临床效果。方法选择36例患者的36颗根管治疗后的磨牙进行临床观察,按照牙体缺损部位分为一类洞型缺损和二类洞型缺损,使用钴铬合金制作高嵌体修复。修复完成后0.5年,1.5年及2.5年进行回访观察。结果36例高嵌体除2例观察末期松动外,其余在观察期内未见损坏,基牙未见继发龋及折裂,边缘密合性良好。36例高嵌体牙龈炎发生率无差别。结论钴铬合金制作高嵌体用于根管治疗后的磨牙修复效果较理想,是一种临床疗效较理想的修复形式,但由于本实验观察期较短,远期效果有待进一步观察。

Objective To evaluate the clinical effect of metal materials for the treatment of post molar teeth with high volume embedded root canal therapy. Methods 36 patients with 36 root canal treatment after treatment were chosen, according to tooth defect site into a kind of hole type defect and two kinds of hole type defect, using cobalt chromium alloy to produce high inlay repair. After the completion of the ifrst half of the year, 1 and a half years and a half years of follow-up observation. Results 36 cases with high block except for 2 cases were observed in the end of observation, and the rest were not damaged in the observation period, and no secondary caries and fracture were found in the abutment teeth. 36 cases of on lay gingivitis was no difference. Conclusion It is ideal for the production of high inlay to be used in the treatment of root canal therapy. It is a kind of clinical curative effect, but the long-term effect needs to be further observed.
