Abstract
Relevance. The restoration of a high-quality anatomical and functional contact point of teeth plays an important role in preventing the development of localized forms of periodontal disease.
Purpose. Development of recommendations for qualitative anatomical restoration of the contact point of teeth for the prevention of localized forms of periodontal diseases.
Materials and methods. In our study, which consisted of pre-clinical and clinical stages, were analyzed 50 CT scan of the chewing group teeth calculated the ratio of approximal surfaces of molars and premolars to the width of their crowns and computer simulations of the results of restoration of contact point. We also conducted a comparative analysis of wedges of different material with different cross-sectional shapes. At the clinical stage, the restoration of the contact point of teeth in patients according to our recommendations was carried out.
Results. On the basis of the data obtained during the study, a formula for calculating the height and size of the restored contact point was compiled. Recommendations for anatomical restoration of the contact point are formulated.
Conclusion. The application of the recommendations developed by us allows anatomically qualitatively restore the contact point and prevent the development of localized periodontal diseases.
