. Modern implant systems have different types of connections between the implant and the abutment, in the area of which a microgap can be constructively formed, as a result of which dentists are faced with a loss of bone tissue and inflammatory processes in the area of dental implants.
Objectives ― assessment of the accuracy of the marginal fit of an individual abutment to the implant platform on a sagittal slice.
Methods. Two groups were formed according to the type of connection between the implant and the abutment (conical and planar). Individual abutments for all systems were made using CAD-CAM technology. Using the grinding machine Metaserv 25, sagittal sections of the abutment and implant were obtained. The study and cutting the compound was carried out on a TESCAN MIRA 3 autoemission electron microscope.
Results. Using an electron microscope TESCAN MIRA 3, we obtained images of the surface of the connection of the abutment and the implant on a sagittal slice. When three-dimensional scanning of the studied samples were obtained volumetric images. Measurements of the microgap of the implant compound and abutment on the sagittal split showed that with an increase of x8000 in the first group with a conical connection, the figure varied from 0.27-3.46 microns. In the second group with a planar compound, the index varied from 6.50-9.70 microns.
Conclusions. The ratio of the abutment to the implant with conical connections showed the best results in comparison with planar connections. Using CAD-CAM technology allows you to create prostheses with good marginal fit of the connection between the implant and the abutment.
