Comparative evaluation of the effectiveness of restorations in the cervical region of teeth by direct and indirect method

Abstract

Restoration of cervical lesions of teeth is one of the most urgent problems of modern dentistry. Defects of the cervical region have different etiology, pathophysiology of the development of the defect formation process. The method of direct restoration of defects of various etiologies in the cervical region of the tooth is the most frequent method of restoration. According to many authors, this method is not always effective. One of the initial tasks in dentistry is to replace the lost tooth structure with a material whose composition and physical properties are similar to the natural tissues of the tooth. This goal can be achieved using CAD/CAM technology. The chemical stability of hybrid ceramics provides not only excellent biocompatibility, but also good physical, mechanical and optical properties.
