CLINICAL EVALUATION OF POST-ORTHODONTIC STABILIZATION IN ANTERIOR TEETH USING AN ESTHETIC FULL-CONTOUR LITHIUM DISILICATE RETAINER AND LAYERED LITHIUM DISILICATE RESTORATIONS

Abstract

This study evaluates the use of full-contour lithium disilicate retainers and layered lithium disilicate restorations for the stabilization of mandibular anterior teeth following orthodontic treatment. Lithium disilicate ceramics were selected for their superior strength, biocompatibility, and aesthetic qualities, providing a solution that minimizes discomfort and sensitivity for patients. The clinical performance of these retainers was monitored across 18 cases. Out of the 18 retainers, 10 experienced fractures. Despite the fractures, patients expressed satisfaction with the aesthetic and functional benefits of the lithium disilicate retainers, especially in comparison to traditional metal alternatives. These findings underscore the need for careful material selection and patient education, as lithium disilicate retainers offer a reliable and aesthetically appealing option for post-orthodontic stabilization, though they may require regular follow-up and monitoring due to their susceptibility to fractures.
