영문 초록

The purpose of this study was to verify the split-crest technique experimentally for successful implantation at alveolar bone having unfavorable condition. Using inferior border of the mandible of the canine, we made comparable study about the state of osseointegration between conventional technique and split-crest technique. We set experimental group which was implanted at inferior border of the mandible of the canine by split-crest technique using the fixture of 3.75 mm width and 8mm length, and set control group which was implanted by conventional technique at the counter area of the mandible. The experimental animal was sacrificed at 1, 4, 8 and 16 week. We observed the changing process of bone formation following implantation with stereoscopy, light microscopy, electron microscopy and fluorescent microscopy, and studied histomorphometrically. Histologic results were as follow : 1. In control group, a bit of new bone formation was initiated on a portion of bone defect area at 1 week. The initiation of osseointegration between fixture and new bone was seen at 4 week. New bone tissue with normal shape and structure formed and filled defect area at 8 week. But complete bone remodeling was attained at 16 week. 2. In experimental group, bone formation around fixture was going on actively. But the shape and structure of new bone area was more irregular than that of control group, and bone density was also lower than that of control group. Active new bone formation was still observed at 16 week. 3. The osseointegrated new bone was remodeled to cancellous bone having trabeculae and marrow space composed of compact lamellar bone. 4. In fluorescent microscopic analysis, active bone formation was seen between 4 weeks and 8 weeks at control group. Otherwise, along the all experimental period new bone formation was observed evenly at experimental group. 5. Both control and experimental group, normal osseointegration was accomplished without bone resorption which is essential factor in split-crest technique. As previous results, when implantation using split-crest technique at alveolar bone attenthaving unfavorable condition, early bone formation was delayed slightly, but we could get attentive results along the long term period.
