A new framework design is presented for resin-bonded, acid-etched, fixed partial dentures. This innovative design divided the restoration into two parts, each with a separate path of insertion. The preparation of abutment teeth required minimal reduction and the pontic could not be displaced during function. Thirty-five patients with missing posterior teeth have been treated with this imaginative approach and after approximately 2 years, there have been no debonding failures.
本文提出了一种用于树脂粘结、酸蚀固定局部义齿的新框架设计。这种创新设计将修复体分为两部分,每部分都有独立的就位道。基牙预备所需的磨除量最小,且桥体在功能活动中不会移位。35例后牙缺失患者采用了这种独特的方法进行治疗,大约2年后,未出现脱粘失败的情况。
