This study was designed to evaluate the role of the vascular network regenerated beneath the implant interface epithelium in the prevention of infections arising from the oral cavity. We previously reported in this journal that the vascular network is regenerated from capillaries located beneath the implant interface epithelium 4 weeks after implant placement1). However, even gingivae that appear to be clinically healthy are affected by gingivitis of various grades. The soft tissue around implants, corresponding to the gingiva, is similarly affected, but cannot be correctly evaluated. In studies of the gingiva in dogs, Lindhe, et al. 2) performed plaque control by brushing. Although gingival inflammatory cells could not be completely eliminated, brushing was confirmed to produce marked improvement, both pathologically and histologically. We also performed plaque control of the dog gingiva according to the method of Lindhe, et al. and examined the vascular architecture immediately below the gingival crest epithelium. All specimens examined were found to have a vascular network with a turtle-shell-like structure3).
