METHOD OF TRANSPLANTATION OF A COMBINED OSTEOPERIOSSTEAL GRAFT TO INCREASE THE VOLUME OF THE ALVEOLAR RIDGE BEFORE DENTAL IMPLANTATION (CLINICAL CASE)

Abstract

One of the urgent problems of modern dentistry, and in particular implantology, is the prevention of bone tissue atrophy after removal of teeth from the area of bone periodontal pockets and inflammatory odontogenic neoplasms (radicular cysts), which must be replaced with osteoplastic preparations for the subsequent installation of implants in this area to replace missing teeth. his article is devoted to the description of a clinical case of applying the method of transplantation of a combined bone-periosteal autograft in a patient with atrophy of the alveolar process of the upper jaw in the vertical and vestibulo-oral directions in the zone of 22-24 teeth after removal of an extensive radicular cyst of the upper jaw from the 23rd tooth. The plasty of the alveolar process of the upper jaw before dental implantation was performed with a combined bone-periosteal autograft from the area of the external oblique line and the body of the lower jaw. The result of the operation was monitored using cone-beam computed tomography before, after the operation and 6 months after the manipulations to monitor the state of the bone tissue surrounding the implant and determine the density of bone structures. Before the operation, it was found that the density profile of the subsequent implantation zone was 1502 units palatally, 2014 units in the vestibular zone, and 1998 units in the 24 zone. 6 months after the operation, the density of bone structures was: palatal - 1563 units, vestibular in zone 2.2. teeth - 1358 units, in zone 2.4 teeth - 1603 units. The use of this original technique provides an increase in the efficiency of the implant installation in the area of the replaced bone defect.
