摘要：
The utility model relates to medicine, namely to dentistry, and can be used for dental implantation in the upper jaw and depending on the results of determining the density of the bone tissue of the jaw. An individual dental maxillary implant is made in the form of a truncated cone with a rounded intraosseous end individually for each patient depending on the volume and density of bone tissue in the patient according to cone beam computed tomography of the upper jaw. The implant has a variable-pitch thread on the outside, determined by the non-linear dependence of bone density and thread pitch, and depth, determined by the non-linear dependence of thread depth and bone density. In the inner part of the implant there is a seat and a thread for connecting to the screw-plug or screw of the superstructure - the abutment. The indicated seat has the shape of a hexagon ending in a neck in the form of a bowl near the free surface, the height of the implant is calculated by the formula: h = H - 2.0 mm, where h is the height of the implant, H is the size of the bone block in the jaw selected for implantation, and the maximum diameter of the implant is calculated by the formula: D = A - 4.0 mm, where A is the minimum width of the bone block, D is the diameter of the implant. The utility model allows, under various conditions, including atrophy of the alveolar bone, to maximize the available bone volume for a particular patient, thereby ensuring primary stabilization of the implant and its optimal size, for further effective multi-year operation. 3 ill.Полезная модель относится к медицине, а именно к стоматологии, и может быть использована при дентальной имплантации на верхней челюсти и в зависимости от результатов определения плотности костной ткани челюсти. Индивидуальный дентальный верхнечелюстной имплантат выполнен в виде усеченного конуса с закругленным внутрикостным концом индивидуально для каждого пациента в зависимости от объема и плотности костной ткани у пациента по д
