Abstract
BACKGROUND: Achieving an optimal shade match for these restorations is crucial for aesthetic outcomes. The thickness of zirconia/glass veneer and the choice of implant abutment material play vital roles in determining the final shade of implant restorations.
MATERIALS AND METHODS: This study investigated the influence of zirconia/glass veneer thickness (0.5 mm and 1.0 mm) and implant abutment material (zirconia and titanium) on the final shade of implant restorations. A total of 60 identical implant restorations were fabricated and divided into four groups based on the combinations of veneer thickness and abutment material. The shade of each restoration was assessed using a shade guide, and color differences (ΔE) were measured with a spectrophotometer. Data were analyzed using statistical tests (e.g., ANOVA).
RESULTS: The results indicated that the veneer thickness significantly influenced the final shade of implant restorations. Restorations with 0.5 mm veneer thickness exhibited a lower ΔE value (indicating a closer shade match) compared to those with 1.0 mm veneer thickness. Additionally, the choice of implant abutment material had a minor but statistically significant effect on shade. Zirconia abutments yielded slightly better shade-matching results compared to titanium abutments.
CONCLUSION: In implant restorations, the thickness of the zirconia/glass veneer plays a critical role in achieving a desirable shade match. A veneer thickness of 0.5 mm is recommended for optimal aesthetic outcomes.
