[A retrospective study on the long-term clinical outcomes of 310 porcelain laminate veneers].

OBJECTIVE

To investigate the long-term clinical outcomes of porcelain laminate veneers 1-8 years following delivery.

METHODS

A total of 310 feldspathic porcelain laminate veneers on anterior teeth or premolars in 49 patients were included in the present study 1-8 years following delivery. All the subjects underwent a detailed clinical examination utilizing modified United States Public Health Service (USPHS) criteria. Restoration integrity, abrasion, color satisfaction, marginal discoloration, marginal adaptation, secondary caries, postoperative sensitivity, and gingival index (GI) of the prostheses were evaluated according to modified USPHS criteria. The 1-8 year survival rates of the veneers were statistically analyzed using the life table method.

RESULTS

The survival rates of porcelain laminate veneers were 98.7%, 98.0%, 93.8%, 93.2%, 89.7%, 81.8%, 76.3%, and 76.3% in 1 to 8 years, respectively.

CONCLUSIONS

The long-term clinical outcomes of porcelain laminate veneers are satisfying.
