Two-year evaluation of porcelain laminate veneers using FDI criteria

The use of porcelain laminate veneers (PLVs) is a minimally invasive technique that is often used in restorative dentistry due to esthetic considerations. The aim of this study was to evaluate PLVs according to the Fédération Dentaire Internationale (FDI) World Dental Federation clinical criteria.

This clinical study included 11 patients (7 female and 4 male) who had been admitted to the Uşak University Faculty of Dentistry between February 2019 and February 2021. Before taking part in the study, patients were informed about alternative treatment procedure options. A total of 30 PLVs were fabricated and cemented, and patients were evaluated according to the FDI criteria (with a follow-up after 2 years).

Restorations were evaluated by two trained researchers. During the follow-up evaluation, no fractures or cracks were observed in any restoration. Further, 73% (n = 22) of the PLVs had perfect marginal adaptation and only 27% (n = 8) had small marginal fractures that could be removed by polishing. Moreover, 57% (n = 17) of the PLVs were evaluated as a good color match (no difference in shade and/or translucency), whereas 33% (n = 13) had only minor deviations. In periodontal examinations, 23% (n = 7) of the PLVs had no plaque, inflammation, or pockets, whereas 77% (n = 23) had minor plaque inflammation and no pocket development.

As there were no fractures, fails, or need for removal of the restorations after 2 years, PLVs showed clinically satisfactory performance. The performance of PLVs can be considered highly favorable due to the minimally invasive and periodontally-compatible nature, with a good color match when carefully planned.
