Purpose of research. The use of dental implants as an anchorage for orthodontic treatment causes the highest stresses in the bone tissue with a horizontal load com-pared to a vertical one. It is the horizontal load that can cause mobility and disintegration of the implant, cause resorption or necrosis of the bone around the implant. In the case of using a dental implant only for orthodontic treatment, it is better to use a one-stage technique. Then the implant can be loaded immediately after its installa-tion, invasive procedures are reduced and aesthetic re-quirements are not taken into account.
Materials and methods. Since the intraosseous design and characteristics of OMG orthodontic mini-implants and VKtemp temporary dental implants are comparable, and the biomechanical characteristics of the bone-implant model should not differ significantly, in this re-gard, studies of the mechanical endurance of bones and implants under power load were carried out. There were 4 stages of experimental research: installation of implants at an angle of 15-20 degrees and 90 degrees to the plane of the body of the pig’s rib and 1 kilogram-force (kgf) (9.8 N) and 2 kilogram-force (19.6 N) were used with horizon-tal and vertical load. 2 weeks after application of the load, visual inspection of the ribs (examination was car-ried out under an increase of 2.5 and 3.5 times) revealed no changes in the bone around the implants.
Summary. The implants did not change their initial posi-tion, were motionless and stable. A comparative analysis of x-ray images of the bone tissue of the investigated rib samples made before and after loading did not reveal any morphological changes in the bone around the implants.
