THE DENTAL TECHNICIANS PERFORMANCE STANDARDS IN MANUFACTURING THE SINGLE CROWNS ON IMPLANTS
Abstract
The most common method of dentition of included defects prosthetics using implants is manufacturing of single crowns with fixation on cement or screws. Material can be metal, ceramics, plastics and combinations thereof. These prosthetic rehabilitation techniques of orthopedic patients don’t have a full legal status in Ukraine because of the lack of clinical and dental protocols and professionals time standards for their implementation, which, according to the official methodology of labor determination in prosthetic dentistry, are based on the average norms of time making a particular type of dentures. The aim is to set the duration of laboratory protocols of manufacturing various types of single crowns relying on implants on the basis of the average and actual work time standards of dental technicians. Materials and methods Research object is dental technician technological processes of providing the dental prosthetic aid by manufacturing individual crowns relying on implants; Research subject is the structure, sequence, duration and scope of dental prosthetic stages providing the appropriate aid, specialists labor costs. Research methods: Analysis - to determine the structure and nature of labor costs for dental technician manufacturing single crowns relying on implants, chronometry - to determine the total length of the respective dental stages manufacturing complete dentures with fixation on implants, mathematical - for the determination of departmental regulations of dental technicians time manufacturing complete dentures with implant fixation, statistical - to handle the study. To determine the length of dental protocols and establish dental technicians departmental standard time was used, officially approved by Ministry of Healthcare of Ukraine method of installation labor costs in prosthetic dentistry in V.A. Labunets modification (1999). Results and discussion During the period 2010-2016 chronometry process observations of 29 dental technicians manufacturing, 261 single crown relying on implants on different types of screwed abutments, and plastic burnout abutments were made. On screwed monolithic abutments 61 prosthetic units, on screwed standard abutments - 94 crowns and on plastic burnout abutments - 106 crowns were manufactured. Material ue cermet, repoussage, metal-composit, metal-free ceramics, plastics. 135 crowns were made by brigadier method. Specialists labor costs were indexed according to the officially approved methodic of labor costs installation in orthopedic dentistry on fixed costs of working time (WT), which do not depend on the type and amount of crowns and variable-repeatable (VRT) that are entirely dependent on these factors. The sum of these indicators is the standard time and is given by: ST = WT + K × VRT, where ST - standard time of dental technician manufacturing single crowns; WR - fixed time cost of dental technician; VRT - variable-repeatable time cost of dental technician; K - the amout of one type crowns. The official methodic of labor costs installation in prosthetic dentistry involves determining UOT of dental technicians based on the average time standards of their work. We conducted these calculations of labor experts as on the basis of the average time standards, so on the actual indicators of process time. Averaged standards of the time the dental technicians spent manufacturing 1-2 constructions for 1 patient is less than 20-40 minutes than in the actual standards, and in manufacturing 4-8 units for also 1 patient, they exceed them in 20-100 minutes of working time. According to our research results, data standards objectively are not corresponding to the actual time the dental technician spent making individual crowns relying on implants and can not be the basis for calculating CTU.
