RESUMEN
Temporary prosthesis transformed into a prosthetic prototypes and manufactured by CAD/CAM technologies (computer copy milling) are used to specify the final form of future permanent restoration and to correct occlusal relationships, vertical size of non-removable dentures, and their occlusal surfaces. A progressive loading on bone tissue in the implantation area and soft tissues formation, have been assessed. In this regard, the choice and placement of temporary mini-implants, as the supports for non-removable denture prototypes for the period of osseointegration of two-stage intraosseous dental implants, are the issues of great importance. Temporary dental implants are the object of complex loads of different magnitude, duration and direction. The action of the prosthesis is closely related to load delivery to the surface of dental implant between the components of the system - "implant-temporary prosthesis". According to the study results, minimization of the momentum acting on temporary implants in the mesiodistal direction allows reducing stress level in the areas of permanent implant placement.

An experimental and clinical study was carried out on 76 patients with implant-supported restorations in the posterior zones of the lower jaw, divided in two groups (with no signs of bone resorption around the implants and with resorption signs) and one control group. The results of the study allowed optimizing the angulation of dental implants, providing an opportunity for individual positioning of dental implant in the mandible depending on the direction of functional load.
