COMPARATIVE CHARACTERISTICS OF MATERIALS USED IN DENTAL IMPLANTATION

Abstract

The objective of the research is a review of some characteristics of dental implants’ products and an analysis of prospects of using them in modern medicine.Dental implantation as a high-technology method of restoring the natural anatomical structure has no competitors at present. The advantages of dental implants consist in their high operational dependability, a longer life time, a higher functionality and a lesser rate of complications as compared to the use of complete or bridge prostheses.The materials used in dental implantation for this purpose are rather diverse. Doctors using them rely on extensive clinical experience, a developed industry of accessory materials, instruments, that is everything that ensures comfortable work and conveniences for the patient.At the same time, the data mentioned in the article testify to the effect that ceramic implants as compared to titanium alloy implants have comparable or better indices. This is guaranteed, for example, by the requirements of the new international standard ISO6474-2:2012: first-rate strength and wear resistance; thermal stability and corrosion resistance; ceramics’ four point bending strength over 750 MPa.The result of the conducted analysis is a review of using various materials in dental implantation. The author compares the aesthetic indices and durability of titanium or metal alloy implants to those of ceramic ones. The comparison shows that, under the current level of ceramic materials’ structural property, it is actual for dentistry to develop its own methodological approaches in relation to a wide use of ceramic implants and creation of various ceramic mono-implants with the purpose of improving the results of treatment of patients, suffering from secondary partial or complete adentia accompanied by bone tissue deficiency, by applying the methods of dental implantation.
