对161例个别牙缺失病人共行230颗钛芯羟基磷灰石人工牙根种植,病人年龄7～71岁,男性91例,女性70例。根据植区不同的解剖条件,采用四种种植方式,其中立即种植73颗,早期种植42颗,延期种植87颗,牙槽嵴增宽后种植28颗。6颗种植失败,230颗种植体中186颗已完成上部修复,132颗术后随访1年以上,24颗超过2年。本文对种植材料选择、临床适应范围、防止骨热灼伤以及上部牙冠修复要点进行了讨论。 A total of 230 dental titanium hydroxyapatite artificial tooth roots were implanted in 161 cases of individual dental loss patients. The patients were 7 to 71 years old, 91 males and 70 females. According to the different anatomical conditions, four planting methods were used, of which 73 were planted immediately, 42 were planted early, 87 were postponed, and 28 were planted after the alveolar ridge was broadened. 6 implants failed, 186 of the 230 implants had undergone upper repair, 132 had been followed up for more than 1 year, and 24 had been over 2 years. This article discusses the selection of implant materials, the range of clinical adaptation, the prevention of bone heat burns, and the main points of crown restoration.
