Abstract: Objective To evaluate the clinical application of lithium disilicate glassceramic in the treatment of small anterior teeth restoration. Methods 87 teeth of 45 patients were restored by IPS e.max press ceramic veneers. The teeth underwent a detailed clinical examination according to the modified California Dental Association (CDA)/Ryge standards including marginal fitness, ceramic surface, color match, sensitivity, gingival health after 1 month, 6 months, 12 months, 24 months and 36 months. Results 11 teeth showed the sensitive symptoms at the review after 1 month and the symptoms were significantly improved after treatment. After 6 months, 9 teeth showed the inflammation of gums and the symptoms were improved after health education and periodontal treatment. Review after 1 month and 6 months showed that all the veneers had good marginal fitness, integrity and ceramic surface. Review after 12 months showed that a veneer fell off, and was reattached to the tooth surface after cleansing. Review after 24 months showed that a veneer collapsed during eating, and the dentin was exposed. The veneer was remanufactured and restored. Only 7 teeth showed obvious gingival retraction at the review after 36 months. Conclusion Lithium disilicate glassceramic veneer is suitable for the treatment of anterior teeth and can achieve good clinical effect and longterm prognosis.
