In this work the results of biometrics research of small defects of dentition with secondary deformations of dentition are presented. The objective is to analyse and compare the results of biometrics research of small defect of dentition and justification orthopedic treatments using the proposed adhesive prosthetic appliances. Materials and methods. After the examination of the patients, biometric analysis of diagnostic models and characteristics of defects of dentition secondary dentoalveolar deformation was found, caused by small defects of dentition and determinated the form, nature, characteristics, signs, complexity of deformation. Results and discussion. When comparing biometric parameters in patients without deformations and with deformations it was found that the distance AB (distance from the center of medial aproxymal surface to the center of aproxymal distal surface in the area of clinical necks of the teeth surrounding the defect of dentition) is reduced to the deformation in comparison with that without deformation. There is quite a significant decreasing in the distance AD (distance from the medial aproxymal surface in the area of clinical neck of the tooth to the center of the distal aproxymal chewing surface). Also the decrease in the width of the alveolar bone was marked. Conclusions. Detailed diagnostics values the defects of dentition, condition of teeth, which limits the defect of dentition and its impact on the development of temporomandibular disorders and the need to prevent the development of secondary deformations, determine the optimal choice of options and methods for recovery of small defects of dentition by using conventional fixed prosthetic dentures, adhesive appliances, methods of implantation or proposed adhesive prosthetic appliances.
