Description: Three different protocols for dental implantation: immediate (ImI), delayed (DI) and conventional (CI) were used. The primary stability is important for the secondary stability of implants. The purpose of the experiments was to monitor the stability of ImI, DI and CI following guided bone regeneration (GBR). A total of 18 implants were placed in the alveoli of 9 extracted premolars of the lower jaw of three mixed breed dogs. GBR was performed with a combination of Bio Oss and Emdogain and the Bio Gide membrane. Control GBR was performed with coagulum and the same membrane. The stability of the implants was measured with Osstellо ISQ. The primary stability of the three types of implants was high, and differed statistically significantly (P<0.05). By the end of the first month after the placement, the stability of ImI and DI was reduced. The secondary stability of ImI and DI increased substantially (P<0.05) by the end of the third month both with regard to primary stability and stability by the end of the first month. The primary stability of intraosseous implants was a prerequisite for a high secondary stability. The decline in stability by the end of the first month after implantation was not an obstacle to achieve a high secondary stability
