Abstract
For the treatment of coronary heart disease (CHD) and the prevention of recurrent attacks of angina, coronary artery bypass grafting (CABG) is considered the most effective method. This operation provides a significant improvement in heart function in 75-80% of cases. This operation provides a significant improvement in heart function in 75-80% of cases. Often the course of the postoperative period in patients with coronary heart disease with concomitant oncological pathology is accompanied by an anxiety-depressive state. To improve the results of surgical treatment, psychological correction methods are used. Despite a significant amount of work on the study of the characteristics of the mental state of cardiac patients, many aspects of this problem remain insufficiently studied. A significant portion of researchers associate the deterioration in the quality of life of cardiac patients with the characteristics of the clinical course of the disease. The source of stress is the fact of being diagnosed with a serious, life-threatening disease in connection with entrenched ideas about the incurability of oncological pathology. In addition, surgical interventions are accompanied by negative emotional experiences. Their result is neuropsychic disorders of varying nature and severity, primarily asthenoneurotic, anxiety and depressive disorders. At the same time, such psychological aspects as the characteristics of the cognitive sphere (CS) of the patient’s personality and their dynamics, as a rule, remain out of focus. The above determined the problem of this study.

Keywords: coronary heart disease, oncopathology, coronary artery bypass grafting on a beating heart, anxiety-depressive state.

Abstract
The author considers the advantages, disadvantages and methods of preventing complications in the prosthetics of patients with fixed overdentures. It has been proven that individual planning of the design of a subperiosteal implant allows creating the most correct location of the support heads in their required number and ensures high-quality fixation of the prosthesis, leaving a specific clinical situation.

Keywords: subperiosteal implant, fixed overdentures, fixation of prostheses.
