COMPARATIVE EVALUATION OF EFFECTIVENESS OF RESTORATIONS IN CERVICAL TEETH REGION BY DIRECT AND INDIRECT METHOD
Journal Title: International Journal of Civil Engineering and Technology - Year 2019, Vol 10, Issue 3
Abstract
Restoration of defects of hard tissues in cervical region of teeth is one of the most topical problems of modern dentistry. Defects of cervical region have different etiology, pathophysiology of development of defect formation process. The most frequently used method for restoration of lost hard tissues of teeth is method of direct filling. However many authors believe that this method is not effective enough. One of the main goals of restorative dentistry is to replace lost tooth structure by a material whose structure and physical properties are similar to natural tissues of tooth. This goal can be achieved by CAD/CAM technology. Chemical stability of hybrid ceramics secures its good mechanical and optical properties as well as excellent biocompatibility. A restoration of cervical region must be subjected to several different types of loads, one of them are temperature fluctuations in oral cavity. The article studies influence of thermocyclic loads on state of boundary "filling-tooth". The experiment proved that indirect restoration of hybrid ceramics is more resistant to thermocyclic loads.
