Abstract
The aim of the study: development and clinical testing of specialised dental instruments and a clinical protocol for the restoration of the age-re-lated characteristics of contact pads during caries treatment of the contact surfaces of posterior teeth applying aesthetic restoration using light-cured composite materials.Materials and research methods. A contact-former of an original design and a medical-technological algorithm for the formation of contact areas of the posterior teeth, taking into account age characteristics, have been developed. A comprehensive assessment of the quality of 289 direct composite restorations of posterior teeth with Class 2 defects according to Black made during the treatment of dental caries in 178 pa-tients aged 20 to 59 years was performed. The condition of 162 composite restorations performed using contact-formers and 127 composite restorations performed using the traditional restoration technique, without the use of contact-formers and other similar tools and techniques.Research results. The compliance of the restorations performed using the developed technique, according to the criteria for restoration of the contact surfaces of the teeth (4 points), was 98.3 ± 1.02% after 7 days after treatment, 92.5 ± 2.07% after 12 months, and 24 months after – 74.8 ± 3.41%. In the comparison groups, 16.3 ± 3.28% (p<0.005) restorations were fully consistent with the clinical requirements for this indicator (4 points) 7 days after treatment, 11.3 ± 2.81% (p<0.005) after 12 months, after 24 months this indicator decreased to 9.8 ± 2.64% (p<0.005).Conclusion. The data obtained make it possible to recommend the use of a contact-former of the original design and the method of restor-ing planar contact points (contact pads) taking into account age-related characteristics within the framework of a personalized approach in the treatment of patients with caries of the contact surfaces of posterior teeth by the method of direct aesthetic restoration with light-cured composite materials.
