Units of labor input of orthopedists during consultation for implants. Fixed restorations

Abstract

Implant-supported fixed restorations are widely used in practice with the aim of prosthetic rehabilitation of edentulous patients; however, in Ukraine, the aforementioned methods are currently not completely lawful due to the absence of departmental standards of time needed for orthopedists to manufacture such types of dentures.In prosthetic dentistry, labor inputs are determined based on the average standard working time for professionals that not always correspond to the actual time expenditures which must be taken into consideration when determining the appropriate units of labor input. The objective of the research was to determine the units of labor input of orthopediststo manufacture implant-supported fixed restorations.Materials and methods. The object of the research involved clinical processes of manufacturing implant-supported fixed restorations.The units of labor input were determined based on the average time standards obtained in the result of timing measurements of clinical processes of providing appropriate care.The conversion of the obtained time standards (TS) to the units of labor input (ULI) was performed according to the formula: ULI = Tts / T1uliResults and discussion. Clinical processes of manufacturing 69 single implant-supported restorations by 15 orthopedists were studied. There were manufactured 13 crowns with screw-retained solid abutments, 21 crowns with screw-retained abutments, 17 single abutments, 18 screw-retained crowns with burn-out plastic abutments or abutments with a platform for attaching and pressing.In addition, the work of 18 orthopedists who manufactured 30 implant-supported bridges including 8 prosthetic dentures with screw-retained solid abutments, 10 prosthetic dentures with screw-retained abutments, 12 screw-retained dentures with burn-out plastic abutments or abutments with a platform for attaching and pressing was investigated and timed.The results of the research showed that the initial values of the labor input indicators when manufacturing single implant-supported fixed restorations were within the range of 1.5-1.5 ULI (the average values) and 3.3-3.5 ULI (the actual values) depending on the prosthetic construction. When manufacturing implant-supported bridges, the indicators were as follows: the average values – 2.1-2.3 ULI, the actual values – 3.6-3.9 ULI depending on the prosthetic construction as well. Conclusions. The results obtained due to timing measurements of clinical processes of manufacturing implant-supported fixed restorations, their analysis as well as the calculations of the standard time showed that the units of labor input of orthopedists determined on the basis of the average time standards did not coincide with the units of labor input of manufacturing these prostheses determined on the basis of the actual time standards.
