RESUMO
The purpose of this study is a comparative analysis of the effectiveness of the use of dental trays-transformers for the manufacture of prosthetic designs for elderly patients with acquired microstomia. Was conducted a clinical study of 12 hemimaxillectomy patients from 60 to 72 years. The 1st group included 6 patients with acquired microstomia, impressions of the jaws were obtained with dental trays-transformers. The 2nd group includes 6 patients who have less traumatic oral opening, they were removed with standard dental trays. The group of clinical control consisted of 6 patients with partial absence of maxillary teeth, who needed to prosthetic dentistry. The results of the study indicate the effectiveness of the use of trays-transformers to impressions of the jaw in elderly patients with restricted oral opening, as well as in patients with normal oral opening. Optimization of the stages of obturator prostheses allows to provide qualitative prosthetic care of patients with malignant neoplasms of the oropharyngeal region, which has a positive effect on the quality of life of elderly patients with acquired defects of the oropharyngeal region.
