In the modern practice of a dentist, there are quite often cases of treatment of patients with a destroyed crown part of the teeth. This problem is caused by the action of carious factors, the traumatic component, as well as cases of pathological tooth wear. To successfully treat such defects, today all possible designs are used, the basis of which are pins made of various materials. In most cases of patients visiting a dentist to eliminate a defect in the crown part of the tooth, patients come with a clinical situation when IROPZ exceeds 80%. In such cases, it is acceptable to make stump pin tabs by casting. This is justified by the fact that such structures are made in one piece, in contrast to the stump structures made using pins. The latter are made in the oral cavity using light-curing composite materials. However, the long-term results show the failure of such structures, due to the loss of crowns based on such structures. As practice shows, these phenomena occur due to the destruction of the crown part of the stump pin structure, which apparently does not withstand the masticatory load. Also, breakdowns are possible due to insufficient light curing in the narrow mouths of the root canals, which do not get the rays of the light-curing lamp. Detailed studies of such cases are covered in our other articles. Focusing on the methods of manufacturing cast stump pin tabs, we can say that direct and indirect manufacturing methods are described in modern literature. Purpose of the study. Improvement of the method of manufacturing a stump pin insert for the restoration of single-rooted teeth. Materials and methods. In our article, we present an improvement of the direct manufacturing method, by using the author's device for the manufacture of a stump post insert. Results. The traditional methods of making stump pin inlays and the method proposed by us are compared. A study on the speed of manufacturing wax reproductions of stump pin inlays for central, lateral incisors, canines, premolars was carried out using direct and indirect manufacturing techniques and a technique improved by us. Conclusions. As a result of the use of our device, it is possible to reduce the manufacturing time of the wax composition of the stump pin tab and to obtain a cast stump pin tab with a high degree of marginal fit in the end.
