영문 초록

The purpose of this study was to evaluate the tissue reaction around the implnts installed by maxillary sinus lifting technique. The edentulous area was provided by extracting left maxillary molars of mature female dog. After healing, the cylindrical screw and basket type titanium implants were installed by sinus lift technique and the sinus was filled with non-resorbable HA. The specimens were obtained after 6 months’ osseointegration period and radiological and histological studies were performed on the peri-implant tissues. The results were as follow ; 1. The two types of titanium implants which were installed into maxillary sinus were maintained healthy condition without mobility and inflammation. 2. The surrounding area of the implant and HA granules showed osseointegrated bone when observed by radiological and histological study. 3. In the view point of histology, mild infiltlation of inflammatiory cells was found beneath of soft tissue epithelium at the recipient site of the implant, and the prepared edentulous bony site was covered with bone tissue. The part of HA filled interface was covered with bone tissue and connective tissure partially 4. In the area filled with HA, HA granules which were close to sinus wall were mostly surrounded by bone, and those which were far from sinus wall were surrounded by connective tissue. 5. The membrane of maxillary sinus maintained healthy condition without any evidence of inflammation.
