This work summarizes the experience of using modern methods of radiation diagnostics in combination with computer and telecommunication technologies in planning reconstructive operations in neurosurgical and maxillofacial practice. Modern medicine does not stand still, it is constantly developing and improving. Thanks to the emergence of high-tech medicine today, it is possible to carry out complex surgical operations and to give a person who has faced serious injury, to continue a fairly high-quality and full life. The creation of a digital model and the use of computer simulation using the data of a particular patient, was a real breakthrough in medicine, because this technology is very quickly found its practical use in many areas of surgery. To date, this approach in the planning of reconstructive surgery has already been tested in many medical institutions and makes a significant contribution to the development of modern medicine.

The model of crosslinking polymerization in photopolymer for laser stereolithography has been proposed. The feature of this polymerization is that the initiation takes place by an irradiation with single pulse that should be enough to solidify the chosen parts of photopolymer. It is shown that despite of such initiation the polymerization passes the gel point due to the fast forming and crosslinking of polyradicals resulting in gel macromolecules. The influence of different factors (termination, trapping, crosslinking, cyclization) on position of the gel point is investigated. Branched level of macromolecules formed during polymerization is found to be mainly dependent on the rate of cyclization.

ч ы а:, , , .The paper reports on the technological features of using the multicomponent photocurable resins by the example of a new resin I LIT-4 to achieve the best characteristics of the cured parts. It was found that repeated drawing of the layer with a proportional increase in the speed of drawing thin spots of the part improves the physical and mechanical characteristics.
