Two-year performance of glass-ceramic insert-resin composite restorations: clinical and scanning electron microscopic evaluation.
OBJECTIVE
This study evaluated the 2-year clinical performance of beta-quartz-resin composite restorations.


METHODS
Twenty-two glass insert-resin composite restorations were placed. Restorations were placed in 6 molars, 12 premolars, and 4 incisors. After 2 years, clinical assessment of the restorations was made by three operators according to the US Public Health Service criteria. Scanning electron microscopic evaluations were made by replica technique.


RESULTS
Nineteen restorations were graded Alfa and three restorations were graded Bravo for color match. Twenty-one restorations were graded Alfa and one restoration Charlie for proximal contact, marginal integrity, and anatomic form. None of the restorations showed marginal discoloration, tooth sensitivity, or caries.


CONCLUSIONS
Glass-ceramic insert-resin composite restorations exhibited excellent performance after 2 years of clinical service.
