The purpose of this study was to compare early wound healing processes in the lingual periosteum and bone
after linguo-cortical perforation of mandible on beagle dogs using 2 different types of crestally approached sinus
membrane lifting instruments.
Four mandibular premolars in each 3 beagle dogs were extracted. After 2 months of healing period, 3 osteotomy
sites were prepared with the diameter of 3 mm implant drill from buccal to lingual side without perforation. Then
the cortical plates of each hole were perforated without tearing of periosteum using OSC 018, OSC 026, and the
diameter of 3mm hatch reamer according to each manufactures recommendations. The wound healing processes in
periosteum and bone were compared on the day of operation, 3 and 7 days after operation histologically and immunohistochemically
through the expression of TGF-ß1.
More bony destruction was observed in the Hatch reamer group. However on the 7th day after operation similar
periosteal healing processes were observed in all 3 groups. This study contains laboratory limitations because it
did not apply directly to sinus membrane. In the future, more successive studies of healing process will be needed
following early healing phase by increasing the number of animals and by extending experiment a l periods.
