[The use of the Periotest method for the clinical assessment of the efficacy of dental implantation]. / Primenenie periotest-metoda dlia klinicheskoi otsenki éffektivnosti dental'noi implantatsii.

The paper describes a modern diagnostic method: Periotest for assessing the stability of intraosseous implants. The mobility of implants after remote and immediate implantation is assessed in 65 patients with dentition defects. The study yielded complete information on the status of tissue complex, detected the early signs of impaired bone integration after implantation, and helped more reliably predict the results.

[The clinical assessment of the efficacy of using a biogenic composite material in dental implantology]. / Klinicheskaia otsenka éffektivnosti primeneniia biogennogo kompozitsionnogo materiala v dental'noi implantologii.

A new biogenic composite material based on hydroxyapatite and collagen with silamine was effectively used in dental implantology. Use of this material was conductive to a better course of the implant integration in the adjacent tissue structures and prevented the development of resorptive and atrophic changes in the alveolar process. Use of composite material in patients with relative indications for implantation precluded the development of complications in the early postoperative period and in remote periods of the follow-up.

[Diagnostic possibilities of precordial electrocardiographic mapping in the assessment of the results of dipyridamole test in patients with ischemic heart disease]. / Diagnosticheskie vozmozhnosti prekordial'nogo élektrokardiograficheskogo kartografirovaniia v otsenke rezul'tatov dipiridamolovogo testa u bol'nykh ishemicheskoi bolezn'iu serdtsa.

The dynamics of cross-sectional, isochronic, and integral maps of electric potential distribution during the dipyridamole test was examined in 35 patients with verified coronary heart disease and 12 control patients. Basic differences were found in changes of excitation propagation velocities and positive potential amplitude in the groups examined. A local increase in R wave areas on the maps of positive potential differences was found to be the most significant mapping sign of transient myocardial ischemia (the sensitivity, specificity, and diagnostic accuracy being more than 97%). The diagnostic accuracy of an absolute or relative increase in the integral time and amplitude parameters of the mapping was 77% and 70%, respectively.
