Up to now the CAD/CAM system with zirconia has the highest fracture strength in all all-ceramic materials, and consistently enabled the most esthetic, lifelike reproduction of natural dentition. They have been widely received by both dentists and patients. The CAD/CAM system with zirconia is indicated for crowns and bridges in natural teeth or implants and telescope dentures, the CAD/CAM with zirconia can be placed anywhere in the mouth, and can replace the porcelain crowns and bridges for single crown and bridges less than 6 units.

文摘目的评价计算机辅助设计与制造(computer aided design and computer aided manufacturing,CAD/CAM)新型纳米复合陶瓷Lava Ultimate髓超嵌体和长石质瓷Vita TriLuxe髓超嵌体修复根管治疗后牙体缺损的临床效果。方法选取2017年1—12月于南京市口腔医院牙体牙髓病科就诊的58例患者根管治疗后缺损磨牙60颗,随机均分为两组,其中观察组30颗,采用Lava Ultimate髓超嵌体修复;对照组30颗,采用Vita TriLuxe髓超嵌体修复。根据改良美国公共卫生署(United States Public Health Service,USPHS)标准,比较两组临床修复效果。结果 60颗修复体均效果良好,无修复体脱落,仅在对照组发现1例修复体折裂情况;观察组在边缘密合性、完整性、继发龋和牙龈炎症方面与对照组比较,差异无统计学意义(P> 0.05);但观察组的对颌牙磨耗情况轻于对照组,差异有统计学意义(P <0.05)。结论 Vita TriLuxe髓超嵌体和Lava Ultimate髓超嵌体皆可用于修复根管治疗后的牙体缺损,新型纳米复合陶瓷Lava Ultimate相较于长石质瓷Vita TriLuxe更能减少对颌牙的磨耗,值得临床推广应用。
