The therapeutic goal of implant dentistry is not merely tooth replacement but total oral rehabilitation. Considering dental implants as a treatment option can be provided patients with positive, long-term results. Implant dentistry has gone through many phases over the years. Modern technology and design allows us to predictably place our dental implants often load the implants at the time of placement. The purpose of this study is to evaluate the implant stability after immediate loading in dogs. The control group was performed delay loading and experimental group was immediate loading. Each group was measured periotest value(PTV) to evaluate clinical mobility and performed radiographic examination to evaluate marginal bone loss. Statistically significant difference was not founded in control group between experimental group in PTV(P>0.05) and marginal bone loss(P>0.05). Finally, implant stability after immediate loading was similar to delay loading implant.
