摘要:

目的:采用西诺德CEREC3D牙科椅旁CAD/CAM系统制作全瓷高嵌体修复严重缺损的后牙,探讨其即刻修复质量和短期疗效。方法:选取24例后牙严重牙体缺损患者,使用CEREC3D系统,以长石瓷块为材料,制作24颗全瓷CEREC全瓷高嵌体,以复合树脂水门汀粘结,术后即刻采用改良的美国牙科协会评价标准对修复体各方面指标进行评价,术后3个月对患者进行满意度调查,并检测龈沟液内肿瘤坏死因子α(TNF-α)和基质金属蛋白酶8(MMP-8)含量(以患牙的同侧相邻健康的天然牙为对照组)。结果:24例CEREC全瓷高嵌体无一例失败,一次戴牙成功率达100%,戴牙后3个月患者满意率为100%,短期疗效确切。患牙龈沟液内TNF-α及MMP-8含量与对照组接近,差异无统计学意义(P>0.05)。结论:使用CEREC3D牙科椅旁CAD/CAM系统制作的CEREC全瓷高嵌体可以作为后牙严重牙体缺损的有效治疗方案。

Abstract:

To restore the extensive posterior defection with all-ceramic onlays made by CEREC3D CAD/CAM system and to explore their instant qualities and short-term assessment.Methods Twenty-four patients with extensive postenor tooth-defection were selected to accept the onlay restoration.All the 24 onlays were scanned and designed in CEREC3D  CAD/CAM system and milled out of feldspathic porcelain blocks,and cemented with composite luting agents.The restorations were recalled and assessed using the modified assessment standard of American Dental Association (ADA) after the operation.The patients were recalled after 3 months and received satisfaction survey.The contents of TNF-α and MMP-8 in gingival crevicular fluid were also checked and compared with  control group.Results None of  the 24 restoration failed during the observation period,the satisfaction rate was 100%.The satisfactory rate of the patients 3 months after operation was 100%.The contents of TNF-α and MMP-8 in gingival crevicular fluid was  close to those in control group,there was no statistical significance (P>0.05).Conclusion The feldspar onlays fabricated with CEREC3D chairside dental CAD/CAM system could gain good result in restoring extensive posterior defection.
