BACKGROUND: Pathological abrasion of hard dental tissues is quite common and can result in the partial or complete destruction of tooth crown, followed by disturbances in the entire dentoalveolar system. Such conditions are difficult to treat because both the esthetic component and functional usefulness must be restored, which is not always possible to achieve in the long term. Currently, various methods in dentistry are used to restore the lost crown part in patients with a decompensated form of pathological tooth abrasion by using various types of pins and pin structures, which do not always allow achieving positive long-term results because of failure and breakage during operation.
AIM: To assess the strength characteristics of various stump pin inlays and stump structures.
MATERIALS AND METHODS: Experimental studies of the strength characteristics of various types of stump pin structures were conducted. For this, 45 samples of stump pin structures were made for testing on a ZMGI 250-kp tensile testing machine.
RESULTS: Experimental results revealed the magnitude of the stress at which sample destruction occurs.
CONCLUSION: The study obtained information on the strength of various stump pin structures, which are important in tooth-preserving technologies.
