Abstract

The study was performed on a number of 48 plastic molds, obtained by injection of Technovit 7143. Technovite is a self-curing resin based on methyl methacrylate. Technovite no longer requires the use of dyes that can adversely affect the polymerization process and has a short polymerization time, making corrosion possible shortly after injection.

Highlights

This paper aims to highlight the role of Technovit 7143 in obtaining anatomical molds, which allow the evaluation of morphometry and anatomical variations
Our study was performed on a number of 48 plastic molds obtained by injections of German-made Technovit 7143, a self-curing resin based on methyl methacrylate in powder and liquid form
The origin of the right renal artery in the aorta, followed by a number of 26 cases, i found it above-situated than the origin of the left renal artery in 16 cases (61.53% of cases), with differences of 5, 5-7.2 mm); in 6 cases (23.08% of cases) the origin of the left renal artery was abovementioned, with differences between 6.1-7.1 mm; in 4 cases (15.38% of cases) the two renal arteries, right and left, had their origin from the aorta located at the same level, (Figure 1, 2, Table 1)

Summary

Introduction

This paper aims to highlight the role of Technovit 7143 in obtaining anatomical molds, which allow the evaluation of morphometry and anatomical variations It is a relatively new method, and extremely rarely used in Romania but which can be applied to other university centers. We consider it an easy method to apply and with very good research results It was mainly used TECHNOVIT 7143, which is not a toxic substance, is easy and fast to prepare and no longer requires the use of dyes that can negatively influence the polymerization process. The renal arteries are the main arteries of the blood purification, representing at the same time the nutritional arteries of the kidneys and their fat capsule, the calyxes, the basins and the upper part of the ureters They take part in the vascularization of the adrenal glands and lymph-aortic lymph nodes. This disproportion is even more evident when comparing the diameter of the hepatic artery destined for the enormous hepatic gland with that of the renal artery destined for a ten times smaller organ
