The purpose of this study was to investigate the processes of regeneration of bone tissue after the introduction of new implant systems. In the experiment, performed on 10 male pigs of Landras breed aged 50-55 days and weighing 17-18.5 kg, the time course of histological changes was studied in the area of mandibular regeneration after the formation of tissue defect and the introduction of the implant of a proposed construction. Morphological analysis of the experimental results 90, 180 and 270 days after the operation demonstrated the process of reparative regeneration of damaged bone along implant-bone block boundaries. Bone repair proceeded through the stage of formation of the woven bone with its progressive substitution by the lamellar bone, with the maintenance of the shape, size and symmetry of the damaged organ.

Background: Traumatic anterior shoulder dislocation is the most common type of joint dislocation, with an incidence of 11 to 29 per 100 000 persons per year. Controversy still surrounds the recommendations for treatment and the available procedures for surgical stabilization.
Methods: This review is based on pertinent publications (2014-2024) that were retrieved by a selective search in the PubMed and Google Scholar databases.

Micro- and nanomorphological modification and roughening of titanium implant surfaces can enhance osseointegration; however, the optimal morphology remains unclear. Laser processing of implant surfaces has demonstrated significant potential due to its precision, controllability, and environmental friendliness. Femtosecond lasers, through precise optimization of processing parameters, can modify the surface of any solid material to generate micro- and nanomorphologies of varying scales and roughness.

The present study investigates the potential contribution of Photobiomodulation (PBM) to the regeneration of the bone following the extraction of the first mandibular molar in rats. The study evaluates the efficacy of PBM, using both Low-Level Laser Therapy (LLLT) and Light-Emitting Diode Therapy (LEDT), as promotors of osteoblastic activity and the formation of new bone. Study design, setting, and sample: 45 male Wistar rats were divided randomly into three groups of 15 individuals - (i) control group (left lower molar removed only), (ii) the LLL group (molar removed, followed by LLLT), and (iii) the LED group (molar removed, followed by LEDT).

Objective: To evaluate the effectiveness and safety of radiofrequency ablation (RFA) for the treatment of symptomatic distant metastasis of differentiated thyroid carcinoma.
Materials And Methods: The medical records of 12 patients who underwent RFA for the palliative treatment of 18 symptomatic distant metastases from thyroid cancer between January 2008 and December 2020 were analyzed. All patients were assessed for their degree of discomfort and underwent periodical evaluations as outpatients, including clinical examination, imaging, and serologic markers.

Objective: This study aimed to explore and evaluate a novel method for diagnosing patellar chondromalacia using radiomic features from patellar sagittal T2-weighted images (T2WI).
Methods: The experimental data included sagittal T2WI images of the patella from 40 patients with patellar chondromalacia and 40 healthy volunteers. The training set comprised 30 cases of chondromalacia and 30 healthy volunteers, while the test set included 10 cases of each.
