Clinical evaluation of the innovative concept of teeth saving

Abstract

To evaluate the effectiveness of the innovative concept of dental medical technologies in patients with resected (amputated) roots of teeth with and without periodontal diseases. Of the 516 examined patients with periapical destructive foci of infection of various genesis, 4 clinical groups of 24 people were randomly formed: (1) with a diagnosis of apical periodontitis of incisors, canines or premolars with individual milled transdental implants made of zirconium dioxide; (2) patients with a similar diagnosis and concomitant periodontitis of moderate severity with the same implants; (3) patients with periapical destructive process of molars without periodontitis with the same implants. Control group (4) included patients with similar diagnoses with resection of the root apex without implantation. Patients of the study groups were operated in accordance with the developed clinical protocols, including the manufacture and installation of individual transdental implants with fixation in the postoperative period, developed within the framework of tooth-preserving technologies of immobilizing structures. The reinforcement of teeth with resected roots with transdental implants together with immobilization of these teeth in the postoperative period restores the biomechanical characteristics of the tooth 2.7 times more effectively. However, there is a slight change in the mobility of the operated teeth in an earlier period (after 3 months), which is associated with the resorption of the bone-replacing agent used to fill the intraoperative defect and with the defective formation of bone tissue. The values of peritelomeric 6 months after the operation differ from the control by 1.4 units only.
