This study was attempted to evaluate home-manufactured implants by placing Implant (Lifecore, Co., USA) whose surface is treated with REM that has already been varified clinically, Implant(Chaorum Co., Korea) whose surface treatment is same as that of Stage-1 Implant and Implant(Cewellmedi Co., Korea) whose surface is treated with anodic oxidation immediately after the teeth of experimental animals were extracted to compare histological findings among them. Stage-l Implant(diameter: 3.5mm, length: IOmm), Chaorum Implant(diameter: 3.3mm, length: 8.5mm) and Cowell medi Implant(diameter: 4.0mm, length: 8.0mm) were placed into the mandible premolars of 2 adult beagle dogs immediately after their teeth were extracted, and then histological findings were analyzed at 6 weeks. After those implants were inserted directly after their teeth were extracted, the results of periotest were recorded, radiography was done, the subjects went through thorough control for 6 weeks, and then comparison among periotest, radiography and histological finding was made. After comparison of those findings, the values of periotest were satisfactory and bone healing was relatively satisfactory on radiography at 6 weeks. For osseointegration with the bone tissue, Stage-1 was 45.3%, Chaorum 55.3%, and Cowellmedi 52.5%, which was a satisfactory result. Although implant surgery immediately after teeth were extracted involves difficulties among recent implant surgeries, it is being frequently used in that it may reduce surgery hours, the frequency of surgery, and bone loss for patients. This experiment was conducted to evaluate the technological levels of home-manufactured implants that have been remarkably developed in recent years and in conclusion, those implants showed nearly similar result.
