Dental implantation in the area of previously lost teeth is a modern way to rehabilitate edentulous patients. The search for osteoplastic materials and methods of preimplantation osteoplasty remains topical. One of these materials is an autogenous dentin matrix (ADM), which is based on a crushed extracted tooth. ADM production and application technologies are different and insufficiently tested. Nevertheless, the application of this technique may open up new clinical possibilities. The study on the use of ADM involved 20 patients from 18 to 65 years old. The patients underwent complex surgical and orthopedic treatment to restore chewing function. At the first stage, the extraction of teeth was performed with the simultaneous preservation of the socket of the extracted tooth ADM. The second stage was carried out 3-4 months later, which included the collection of bone biopsy specimen and subsequent dental implantation in the area of the previously extracted tooth. 42 specimens obtained 12-17 weeks after removal were subjected to histological examination. According to its structure, the bone tissue formed in the hole is reticulofibrous bone. Which allows us to conclude that by the time of 15-17 weeks, the processes of active reparative bone formation in the hole are completed, and the necessary local conditions for dental implantation have been created.
