Objective:
This study evaluated the 2-year clinical performance of beta-quartz-resin composite restorations.
Method And Materials:
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.
Conclusion:
Glass-ceramic insert-resin composite restorations exhibited excellent performance after 2 years of clinical service.
