Relevance. Anatomical and functional restoration of an interproximal contact point is an important step in the comprehensive treatment and prevention of periodontal disease. A lot of tools are applicable for interproximal contact point restoration. Since the first application of the first composite material in dentistry, over one hundred instruments have been proposed, with different characteristics and positive and negative features. The variety available on the market may lead to a mistake in the instrument choice, which decreases the dentist's work quality. Purpose. To systematically review the clinical experience in dental instruments used for posterior tooth interproximal contact point restoration.Materials and methods. The review analyzed Russian and international studies on the dental instruments used for posterior tooth interproximal contact point restoration that met the specified criteria. The primary search was performed in the databases Google Scholar, ScienceDirect, PubMed, ResearchGate, and eLIBRARY.RU, using the keywords: контактный пункт, инструмент, матрица, клин, interproximal contact, matrix, wedge, dental instrument in the Russian and English languages.Results. We selected 24 original primary prospective studies on instruments for an interproximal contact point restoration certified in Russia. All instruments were divided into two groups: matrix systems (Palodent V3, HAWE SuperMat, TOR VM) and additional instruments (Contact-Pro-2, OptraContact).Conclusion. The experience of the instruments’ clinical application and the history of their creation have demonstrated a shift towards the anatomically-guided reconstruction of lost tissue. Thus, developing a tool for the anatomical and functional restoration of an interproximal contact point is a challenge for modern dentistry.

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.
