After single crystal alminum oxide implant was inserted on the mandibles of adult monkeys, the implant head was cemented to the superprostheses. Under occlusal function, the gingival response surrounding the implant was histopathologically examined by light microscopy and scanning electron microscopy. The results were as follows : At the gingival-implant junction, the junctional epithelium adjacent to the implant was elongated slightly more downward than that of the neighboring teeth. However, only 2-4 layers composed of squamous cell were flatly ranged along the implant surface and no prominent hyperplasia or proliferation was observed. In the lamina propria of the gingiva, mature and dense collagen fibers were arranged in various patterns. The collagen fibers adjacent to the implant surface were arranged circumferentially and densly. Thick collagen bundles were composed by thin collagen fibers encircled the implant. Most of the mass formed by thick collagen bundles were arranged in parallel to the implant axis. On the basis of the above findings, it was demonstrated that the gingival response surrounding the implant was distinguished from that of the normal tooth periodontium. Therefore, it would be suggested that maintenance of the superior oral hyginene is one of the critical factors for longevity of the implant.
