[The significance of using the method of shared decision-making in preparing patients for orthognathic surgery].

Objective: Evaluation of the effectiveness and impact of the shared decision-making method on patient satisfaction with the quality of preoperative preparation for combined (orthodontic and surgical) treatment.

Material And Methods: The study included 97 patients with skeletal forms of distal and mesial occlusion, who were prepared for combined (orthodontic and surgical) treatment using the shared decision-making method. The effectiveness of the shared decision-making technique used in preparing patients for combined treatment was assessed by means of a questionnaire developed.

Comparative Effectiveness of an Autologous Dentin Matrix for Alveolar Ridge Preservation.

An urgent issue is the preservation or reconstruction of the volume of bone tissue in planning and surgical treatment in the fields of medicine, such as traumatology, orthopedics, maxillofacial surgery and dentistry. After tooth extraction, resorption of the bone tissue of the alveolar crest of the jaws occurs, which must either be further eliminated by performing additional operations or using osteoplastic material for socket preservation at the extraction stage. The aim of the study was a comparative analysis of various osteoplastic materials used to preserve the volume of bone tissue in the preimplantation period.

Morphological Evaluation and Immunohistochemical Analysis of the Reparative Potential of the Buccal Fat Pad.

: There are many surgical techniques for oroantral communication treatment, one of which is the buccal fat pad. Of particular interest is the high reparative potential of the buccal fat pad, which may be contributed to by the presence of mesenchymal stem cells. The purpose of this work is to evaluate the reparative potential of BFP cells using morphological and immunohistochemical examination.

An In Vivo Rat Study of Bioresorbable Mg-2Zn-2Ga Alloy Implants.

In the present study, pins made from the novel Mg-2Zn-2Ga alloy were installed within the femoral bones of six Wistar rats. The level of bioresorption was assessed after 1, 3, and 6 months by radiography, histology, SEM, and EDX. Significant bioresorption was evident after 3 months, and complete dissolution of the pins occurred at 6 months after the installation.

Corrosion Behavior and Biocompatibility of Hot-Extruded Mg-Zn-Ga-(Y) Biodegradable Alloys.

Fixation screws and other temporary magnesium alloy fixation devices are used in orthopedic practice because of their biodegradability, biocompatibility and acceptable biodegradation rates. The substitution of dissolving implant by tissues during the healing process is one of the main requirements for biodegradable implants. Previously, clinical tests showed the effectiveness of Ga ions on bone tissue regeneration.
