FIELD: medicine; dentistry.
SUBSTANCE: group of inventions includes four variants of a dental implant, relates to the field of medicine, in particular, to dentistry, and is intended for use in dental prosthetics on implants. In the first embodiment, the dental implant contains a coronal area and the main area, passing into each other, with the coronal area forming the proximal end of the implant and the main area forming the distal end of the implant, and the coronal area is made with a smaller outer diameter, than the outer diameter of the main section. Main section has an internal core provided with a thread extending from it along its length, wherein the rod forms the internal diameter of the main section and the thread forms the external diameter of the main section. Rod runs along the length of the main section, having a successively decreasing diameter, so that the proximal diameter of the rod is larger than the distal diameter of the rod. Rod includes at least one thread extending from it along the length of the main portion, with each thread comprising an apical side, a crown side and a lateral edge, connecting the apical side and the crown side, the base connecting the thread with the rod, the depth of the thread formed between the side edge and the base. Rod is made of at least two sub-segments, representing the proximal sub-segment and the distal sub-segment. At least one thread has a variable depth, which essentially increases along the length of the proximal subsegment in the apical direction and substantially decreases along the length of the distal subsegment in the apical direction, so that the smallest thread depth is adjacent to the coronal section of the rod and the greatest thread depth is between the distal subsegment and the proximal subsegment.
EFFECT: inventions widens the range of tools for the specified purpose.
