Relevance. Orthodontic mini-implants are often used as anchorage for orthodontic movement. There is currently no consensus on what has a decisive impact on the primary stability of mini-implants. Methods and Materials. The study used orthodontic mini-implants with a diameter of 1.2 mm and lengths of 8 mm and 10 mm, with necks of 1.5 mm and 3 mm, which were inserted into the cortical bone of calf ribs, and their primary stability was measured using the Anycheck device. Results and Discussion. When the mini-implants were inserted with the neck submerged by 1 mm into the bone, the indicators of primary stability were higher and significantly different from the indicators when inserted up to the neck level. Conclusions. A significant increase in primary stability was observed when the neck of the mini-implant was submerged by 1 mm into the cortical bone plate. The torque, length of the intraosseous part and neck of the mini-implant did not have a statistically significant impact on its primary stability.
