About this study
Official title: Improving Orthodontic Treatment of Patients With Dental Retention
The relevance of the research topic is beyond doubt, since this work is devoted to improving the effectiveness of treatment of patients with permanent teeth that have not erupted in a timely manner. Currently, this pathology occurs in 4-18% of patients seeking specialized help in a dental clinic.
The anomaly of teething, first of all, affects the anatomical, functional and aesthetic characteristics, there is an influence on the psycho-emotional state of the patient. Despite a significant number of scientific studies by domestic and foreign authors, some features of the treatment of patients with dental retention are insufficiently covered and systematized. At the moment, there is no optimal approach to the diagnosis and treatment of dental retention, as a result of which there is a question of improving the effectiveness and quality of orthodontic treatment of patients with a diagnosis of "tooth retention".
Read the detailed description
The purpose of the study Improving the effectiveness of treatment of patients with dental retention. Research objectives
- To determine the frequency of occurrence of dental retention according to the patients' requests for orthodontic care;
- Based on the cephalometric study to identify the features of the structure of the face and bone structures in patients with dental retention;
- Develop and implement an orthodontic device to obtain additional space in the dentition in patients with retention;
- To develop and introduce into clinical practice a method for creating surgical access to retentive teeth using digital technologies.
- To conduct a comparative analysis of the effectiveness of our proposed improved stages of treatment of patients with dental retention with well-known methods based on gnatic and profilometric indicators.
Materials and methods of research At the first stage of our study, it is planned to examine patients aged 15-35 years who have applied for specialized
