Ukrainian Consensus on Diagnosis and Management of Vitamin D Deficiency in Adults.

Vitamin D deficiency (VDD) is a global problem, however, there were no Ukrainian guidelines devoted to its screening, prevention, and treatment, which became the reason for the Consensus creation. This article aimed to present the Consensus of Ukrainian experts devoted to VDD management. Following the creation of the multidisciplinary Consensus group, consent on the formation process, drafting and fine-tuning of key recommendations, and two rounds of voting, 14 final recommendations were successfully voted upon.

FEATURES OF BONE REMODELING AROUND SURFACE-MODIFIED TITANIUM AND TANTALUM IMPLANTS.

Objective: The aim: To study the osseointegrative properties of titanium and tantalum implants with different surface structures in animal experiments.

Patients And Methods: Materials and methods: The histological and morphometric study was carried out on 60 male white rats after titanium implants with different surface structures made by 3D printed technology were inserted in the distal femur bone: presented by the multilayered layers of interlacing pores of 300 microns (series 1); rough (> 2 microns) (series 2); and tantalum implants with 300 microns pores and 80% porosity (series 3) as control material.

Results: Results: On the 30 days we found statistically significant differences in the bone-implant contact rate between the 2nd experiment series (44.

EXPERIMENTAL STUDY OF BONE REBUILDING IN THE PERIIMPLANTATION AREA UNDER IMMEDIATE LOADING ON DENTAL IMPLANTS.

Objective: The aim: Study of the dynamics of morphological rearrangement of bone under conditions of immediate occlusive functional load and the effect of splinting of implants with temporary orthopedic structures with the analysis of the coefficient of stability of implants during immediate implantation in the experiment.

Patients And Methods: Materials and methods: A series of experiments was performed on 6 male Duroc pigs at the age of 6 months and weighing 40-60 kg. In the course of recent advances, the following methods have been used: the clinical protocol of immediate - implantation of time-consuming clothes, the definition of COEFICIENT, morphometry and light microscopy of the slides, statistical analysis.

REACTIVE-ADJUSTABLE RESTRUCTURING OF STERNUM IN RATS AFTER MODELING OF MECHANICAL LOADING IN THE BIOMECHANICAL SYSTEM "STERNUM-RIBS-SPINE".

Aim of the research - to conduct histological analysis of the sternum immature rats after modeling mechanical loading in the biomechanical system "sternum - ribs - spine". The studies were conducted on 14 rats. In 8 rats a spinal deformity was simulated according to the method of Sarwark JF et al.

[BONE REGENERATION AFTER THE FILLING OF DEFECTS BY GRANULES OF CERAMIC BIOMATERIAL BIOMIN TGG-2].

Purpose of the study - to study the features of bone regeneration under conditions of filling metadiaphyseal defects with granules of biphasic calcium phosphate with β-tricalcium phosphate of a needle structure. The study was conducted on 24 white laboratory rats. А metadiaphyseal defect (3 mm) was reproduced in the distal femur with dental boron, followed by its filling with granules of TGg-2 ceramic biomaterial.
