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.

Abstract Context The diagnosis of osteoporosis and assessment of fracture risk prior to a sentinel fracture was transformed by the widespread clinical use of dual-energy X-ray absorptiometry (DXA) for the assessment of bone mineral density (BMD). Evidence Acquisition This review is based on a collection of primary and review literature gathered from a PubMed search of “dual energy X-ray absorptiometry,” “trabecular bone score,” and “atypical femur fracture” among other keywords. PubMed searches were supplemented by the authors’ prior knowledge of the subject. Evidence Synthesis While uncertainty exists for some aspects of osteoporosis care, patient and clinician familiarity with BMD assessment for screening and monitoring is firmly established. Beyond BMD, lateral spine images obtained with DXA can diagnose osteoporosis and refine fracture risk through the detection of unrecognized vertebral fractures. In addition, analysis of DXA lumbar spine images can reflect changes in trabecular bone microarchitecture, a component of bone “quality” that predicts risk of fracture independent of BMD. Finally, monitoring of bone health by DXA may be extended to include assessment of the femoral cortices for rare but serious adverse effects associated with antiresorptive therapies. Conclusions Increasing technologic sophistication requires additional consideration for how DXA imaging is performed, interpreted and applied to patient care. As with any test, clinicians must be familiar with DXA performance, pitfalls in analysis, and interpretation within each clinical context in which DXA is applied. With this perspective, care providers will be well positioned to contribute to continuous improvement of DXA performance and, in turn, quality of osteoporosis care.
