PHYSICAL PROPERTIES OF BIODEGRADABLES AND BIOLOGICALLY COMPATIBLES COPOLYMERS AFTER IMPLANTATION UNTIL ITS COMPLETE RESORPTION

Abstract

This article discusses the physical properties of the unique product – biodegradables and biologically compatible co-polymers, which is used for production of absorbable surgical sutures. The absorbable surgical thread is obtained by extrusion of L-lactide-ε-Caprolactone Copolymer (P(LA/CL)) polymers. The main feature of polymer products - complete absorption over a long period of time - is one of the most important parameters for plastic surgeons to achieve effective results. Absorbable threads with barbs are characterized by long absorption. In addition, one of its main features is that after implantation under the skin, it maintains a firm fixation on a specific segment in accordance with the correction of wrinkles.

This article demonstrates the results of observations on the properties of the threads after their implantation in-vivo , in the subcutaneous tissue of rabbits and estimates the time of complete absorption. The aim of this study is to observe the properties of barbed threads after their in-vivo implantation in the subcutaneous tissue of rabbits and to estimate the full absorption time, which is the main feature for production of a strong armor of the soft tissues and because this armoring the human face appears sleeker and tighter.
