Relevance. The most important condition for a successful result of dental implantation is high-quality osseointegration of dental implants. In the literature, the issue of the quality of osseointegration is widely covered, which directly depends on the primary stability of dental implants. In the area of bone tissue remodeling, surrounding the installed dental implants, there are permanent processes of bone resorption and its restoration [1][2].The aim is to reveal the reactivity of alkaline phosphatase and osteocalcin in the biological fluid (saliva) in patients after dental implants.Materials and methods. The collection and analysis of clinical material was carried out on the basis of the Clinics of the Samara State Medical University of the Ministry of Health of Russia. Dental implantation surgery was performed in 184 patients aged 32 to 65 years. The gender ratio was 2:3 (40 men and 60 women). The teeth were lost due to poor oral hygiene and caries complications.Results and discussion. At the time of admission of patients to the department of the Department of Prosthetic Dentistry of the Clinics of the Samara State Medical University of the Ministry of Health of Russia, the bulk of the patients had a low hygienic status. The OHI-S index averaged 2.74 ± 0.33 conventional units. (control – 0.50 ± 0.07 c.u.). In order to reduce the negative influence of microorganisms in the supra- and subgingival dental deposits, all patients underwent professional oral hygiene, as well as antimicrobial therapy. At the time of installation of dental implants, the average OHI-S and Müllemann-Cowell index was 0.72 ± 0.06 and 0.57 ± 0.06 conventional units, respectively.Conclusions. 1. The increase in the titer of alkaline phosphatase and osteocalcin during dental implantation is not statistically significant. 2. TCRF in the oral fluid (saliva) exhibits maximum activity by the 14th day, exceeding the initial three times. This indicator remains at an increased level in the period up to six months from the beginning of the operation. 3. Revealing the values of the TRKF titer after the operation of dental implantation is advisable to use as an assessment of the state of trophic processes occurring in the bone tissue.

Subject. In this article, the problem of integrating the repaid teeth has been studied. Data on the fibroosteointegration of the replanted teeth were obtained on the basis of clinical and additional research methods. Goal. To study the features of the regeneration of bone tissue in the periapical zone of the implantable teeth. Methodology. The patient, C., 41, complained of a partial absence of teeth. As a result of examination of the mouth and analysis of the orthopantomogram, significant destruction of the crown part of the teeth of the upper and lower jaws was revealed. Based on the data obtained, a decision was made to remove them with subsequent replantation. Three months after the implantation, an orthopantomogram was performed. According to the data of roentgenography, uniform filling of the root canal with cement along the entire length was revealed, trabecular bone tissue in the region of the tips of the roots of the resplanted teeth is consistent. With the support of the implantable teeth, non-removable cermet structures were installed. Later, prosthetics was performed with removable orthopedic prostheses. Results. After 2 years as a result of a follow-up examination, there was no pathological mobility in the resplanted teeth, the patient did not present any complaints. On intraoral virological images of the teeth 1.1, 1.2, 1.3, 3.4, the trabecular bone tissue in the projection of the apex of the roots is consistent, the inflammatory foci are not revealed. On the whole surface of the roots of the teeth 1.1-1.3 periodontal space can be traced throughout the root. Bone tissue in the region of the roots of these teeth without pathology. This observation may allow us to make an assumption about fibroosteointegration of these teeth. Conclusions. Based on the results of the treatment and analysis of X-ray data from two-year follow-up, we found no abnormal mobility in the resplanted teeth, bone tissue in the apex of these teeth is well-founded, orthopedic structures supported by the resplanted teeth are stable.
