The Duration of the Processes of Virtual Braces Placement by an Orthodontist on the Jaws Digital Models and Modeling and Correction of Templates for Their Transfer to the Oral Cavity

The purpose of this study. Improving the effectiveness of providing dental care to the population of Ukraine by determining the duration of digital protocols of virtual placement of braces by an orthodontist on digital models of the jaws and computer modeling or correcting patterns for transferring braces from models to the oral cavity. Research materials and methods. The first object of the study was dentists providing medical care in the specialty "orthodontics" of various qualifications, working in medical institutions of various forms of ownership in different regions of the country. The subject of the study was the nomenclature of modern types of orthodontic care in Ukraine. The second object of the study was the duration of dental orthodontic care in Ukraine, and the subject of the study is methodological measures and techniques for determining the duration of digital protocols of virtual placement of braces by an orthodontist on digital models of the jaws and computer modeling or correcting patterns for transferring braces from models to the oral cavity and determining the time standards and conventional units of labor intensity of providing appropriate care. Research results and their discussion. Conducting time-based observations of the work of 8 orthodontists who performed 16 digital protocols of virtual placement of braces on digital models of the jaws and modeling or correcting patterns for their transfer to the oral cavity showed that they are quite complex and require mandatory preliminary training,and the duration of the process directly depends on the quality of the obtained digital models of the jaws, the ability of a specialist to work in a computer program, the features of interocclusal relations, oral health, the state of hard tissues of the teeth, this directly affects the place and quality of fixing braces on the teeth. The normative duration of these processes takes 76.63 minutes or 1.3 CUL for the process of virtual placement of braces by an orthodontist on digital models of the jaws and 56.37 minutes or 1.0 CUL for computer placement or adjustment of templates for transferring braces from the model to the oral cavity. The consultation stage respectively lasts 30.06 minutes or 0.5 CUL.
