Clinical AND Functional Changes in the Use OF Zirconium AND Ceramic Bridges
Abstract
Adentia, caries and related consequences significantly affect the structure of the crown of the tooth and become the main problem of modern dentistry. Studies show that dental problems affect from 51% to 93% of the adult population. Currently, dental implantation acts as an advanced method in the system of comprehensive rehabilitation of patients with dental deficiencies. Despite this, non-removable dentures on a dental support are still preferred to restore function in patients with partial tooth loss. Metal-ceramic dentures, which have been considered the standard for replacing missing teeth for more than six decades, are chosen for their natural appearance and durability, which is provided by a metal base under a ceramic coating. This technology is affordable, relatively easy to manufacture, and has been recognized as a significant component of orthopedic practice worldwide. However, prosthetics are associated with the possibility of complications. Complications of prosthetics can include both biological problems such as secondary caries, periodontal diseases, pulp pathologies, and abutment fractures. Technical problems include loss of retention, peeling of ceramics, aesthetic disorders, occlusive defects and structural breakage. These data emphasize the importance of detailed planning of treatment procedures and strict quality control at each stage of prosthetics in order to minimize the risk of complications and improve long-term treatment outcomes.
