摘要
作者对骨内牙种植体上部结构修复后1~5年患者计131例180件进行临床复查,结果:金一瓷、金一塑、金属材料制成的各类型上部结构效果均理想;固位体冠边缘位于龈缘上0.5~2mm为佳;前牙种植义齿 力值明显低于正常天然前牙 力值,后牙种植义齿 力值接近或超过天然后牙;咀嚼效能、部分及全颌固定种植义齿两者无明显差异。失败的5件(2.8%)种植义齿(冠3件、桥2件)与基牙组合、修复材料强度有关。本文还对修复材料、上部结构设计等进行了讨论。
Abstract In this study,131 patients who have 180 implant dentures were investigated clinically after treatments for 1 ̄5 years. It was shown that effects on various types of superstructures fabricated were satisfatory by meatal-porcelain.metal-resion or metal materials.The ideal postion of the maragin of the retainer crown to gingival margin was 0.5 ̄2mm. The blte force of anterior implant dentures were found to be significantly lower than that of natural teeth.The bite force values of posterior implant dentures were near or even higher than that of natural teeth. Masticatory effeciency was not significant different between partial and complete fixed implant dentures. Five implant dentures(three crowns and two bridges)were failed as a result of defect of the strength of abutment teeth or the prosthesis materials.The principles for the design of superstructures and the choice of prosthesis materials have been discussed.
