영문 초록

In order to investigate the influence of functional stress on the tissue reaction around the implants, the tissues around functional, and non-functional endosseous titanium blade-vent implants were observed histologically for up to one year postoperatively. The mandibular left 2nd, 3rd premolar teeth in 4 healthy dogs (about 40 kg B.W.) were removed. Twelve weeks after extraction, titanium implants were implanted into the extracted area. Two implants which had smaller posts compared with natural teeth were implanted very deeply, not to be functional, into the mandibles of the dogs. But the other two implants had relatively large posts, and these were implanted so as to receive functional stress. One year after the implantation the tissue blocks containing the implants were removed. These block sections were fixed in 10% neutral buffered formalin for 2 days and decalcified in 15% formic acid. The buccal side of the blocks were removed with the knife and the implants were detached to the buccal side. The tissue blocks were embedded by paraffin embedding method and then sectioned by 7 /Jim. They were stained with hematoxylin and eosin. The obtained results were as follows. 1. Two layers of fibrous capsule existed around the functional implants. Collagen fibers of the implant-side layer were parallel with the implant surface, and perpendicular or irregular in the bone-side layer. 2. No fibrous capsule was observed around the non-functional implants. The osseous tissue interfaced with titanium was normal compact bone. In this study, existence of fibrous capsule was suggested to have correlation with functional stress.
