    Two-stage surgical protocol, load-free and submerged healing has been regarded as an original protocol for implantation. Recently, immediate loading proved beneficial in shortening treatment time and giving an esthetic appearance during the treatment. If bone of good quality and enough quantity are present, immediate loading has been successfully applied in various indications. The purpose of this study was to evaluate the effect of different lengths (8.5, 10, 11.5 and 13mm) of the fixtures on immediate immediate loading. Thirty-two implants were placed in the mandible of 8 adult female dogs and loaded immediately. All implants had resorbable blasting media (RBM) surface, and were of same diameter (4.1mm) and neck length (1.8mm). After the extraction of the premolars on the dogs, implants were inserted and loaded immediately and stability was tested by periotest and resonance frequency analysis (RFA). Animals were sacrified after 1, 2, 4, 8 and 12 weeks period loading and then measured the stability with same method. One implant, 13mm on 8 week group was failed presumably because of the wide extraction socket, infiltration on the inferior alveolar canal, and overload, etc. Implants with longer fixture lengths were more stable except for 13mm fixture. These results suggest that RFA and periotest are objective and effective methods in assessing implant stability, especially related to the osseointegration. Through periotest and RFA test, osseointegration is more predictable on immediate immediate loading.
