（j）组织学研究很少。尽管在一项研究中没有组织反应的证据，但其他作者发现，在与骨的匹配不准确的地方存在骨关节炎变化。这些作者还发现基台周围的上皮向下生长，最终可能导致种植体本身的组织脱落。因此，非常需要进一步的体内研究。6.现在似乎存在一种手术植入全下颌义齿的方法。我们必须明白，病人必须经过仔细挑选，而医生必须愿意接受一些失败。然而，有许多种植义齿已经放置了五年或更长时间，因此，研究人员可以开始在推荐所有其他方法都失败的技术时感到一定的安全性。
j. Histopathologic studies arc sparse. Although there is no evidence of tissue reaction in one study, other authors find that there are osteoclastic changes where the fit, in relation to the bone, is inac curate. These same authors also find that there is a downgrowth of epithelium around the abutments which eventually might cause a tissue exfoliation of the implant itself. There is a great need for further in vivo studies. 6. A method for surgical implantation of full lower dentures now seems to exist. It must be understood that the patients must be selected carefully and that the profession must be willing to accept some failures. There are numerous implant dentures which have been in place five years or longer, however, so that investi gators can begin to feel a certain security in recommending the technic where all other methods have failed.
