Abstract

Temporary prosthesis prosthetic measures have one of the leading places.

Until recently, the concept of making temporary fixed prosthesis was simple - to make a prosthesis that would cover the supporting teeth and served 2-3 weeks. The term "temporary" (temporary) is quite consistent that notion. But today is more important use of such concepts as "transient" (transitional) or "intermediate" (provisional), which are more specifically suited to temporary restoration which are necessary for a successful prosthesis [4].

Temporary design should satisfy the patient and give him an idea of the appearance of the final restoration. First of all, a restoration and maintenance functions (aesthetics, phonetics, chewing function, etc.), as well as talent-teeth and periodontal stabilization and adjustment of aproximal occlusal contacts. The decision on whether or not clinical material to meet these requirements, depending on the results of research material properties.

The aim of this study is to improve the efficiency of temporary fixed structures based on analysis of clinical stability during operation. Based on preliminary research conducted at three clinical observation selected materials, physical and mechanical properties which were close to one another: Protemp 4 Garant, Struсtur 2 SC, Acrodent.

In a clinical trial 58 patients were involved, who had orthopedic treatment by 38 temporary crowns and 62 temporary non-removable construction which involved 28 supporting temporary crowns. Thus the total number of temporary crowns was 66 units. Among them 26 crowns made from plastic using Protemp 4 Garant, 20 Structur 2 SC crowns and 20 crowns of Acrodent.

Changes in color and marginal fit were determined using modified criteria of the American Dental Association "USPHS-criteria" for the color pattern Chromoscop (Ivoclar Vivadent). Marginal fit and marginal periodontal reaction was determined both visually and tooth-medical probe. Determined and strength designs. The study was carried out immediately after the fixing of the temporary structures, 1 week, 2 weeks and 3 weeks.

It was revealed that the three materials for temporary non-removable prosthetics have been investigated color stability, the land adjoining, periodontal reactions regional and structural design material Protemp Garant 4 showed the biggest benefits of other materials.

It was determined that the major abnormalities that have been studied, falls on the third week of operation of fixed structures in the mouth because we believe that if the clinical situation allows, seek to complete the permanent prosthesis for the first two weeks or move to temporary structures made laboratory, including using CAD / CAM systems.
