초록

Tooth restoration with implant placement have been interested in modern veterinary dentistry. It is important to reduce the interval between the tooth extraction and the insertion of the implants, to determine the restoration time after implant placement in dogs The aim of the this study was to compare the bone mineral apposition rate of immediately loaded implants with an unloaded control during the early healing state in the artificial extraction mandible.
In four Beagles, two premolar sockets (PM2 and PM3) of the both sides of the mandible were installed with a one stage titanium mini-implant with a length of 11 mm and a diameter of 3.37 mm immediately after tooth extraction.
Provisional restroration was given to implants, 3 weeks after implant placement in the left side (immediate loading)and 12 weeks in the right side (delayed loading), respectively. Radiographic and histologic examinations were performed.
Radiographic evaluation revealed no significant difference between two groups. Bone-implant contact was 47.1 ± 8.9in immediate loading and 50.2 ± 8.2 in delayed loading, interthread bone density was 78.7 ± 10.9 in immediate loading and 73.1 ± 15.5 in delayed loading, and peri-implant bone density was 95.4 ± 7.1 in immediate loading and 95.0 ± 5.2in delayed loading, respectively. Three histologic analyses showed no significant difference between delayed and immediate loading. Followed by this study, the immediate loading of implants insterted into fresh extraction sockets after tooth extraction could be considered in veterinary dentistry.
