Abstract
Objective: Achieving optimal esthetics remains challenging due to limited comparative evidence between pink-anodized titanium and zirconium dioxide abutments. The objective of this clinical study was to evaluate the optical outcomes of pink-anodized titanium and zirconium dioxide abutments in the esthetic region.
Methods: Twenty-two subjects with an edentulous site in the maxillary esthetic region with a tooth present mesially and distally were selected for implant surgery along with hard and soft tissue augmentation. Group A received a pink-anodized titanium abutment with a layered lithium disilicate single crown. Group B received a zirconium dioxide abutment with the same prosthesis material. The contralateral natural tooth served as the control group. Optical outcomes were assessed using a spectrophotometer. The CIELAB color coordinates (Commission Internationale de l'Eclairage) were recorded to calculate ΔE values. Vernier calipers, along with an endodontic file, were used to measure the peri-implant soft tissue thickness. The Pink Esthetic Score (PES) was evaluated using digital images of 22 single-tooth implant crowns to assess the surrounding soft tissue esthetics.
Results: Zirconia abutments (Group A) demonstrated superior optical outcomes compared to pink-anodized titanium abutments (Group B). The ΔE values for Group A at the peri-implant soft tissue, coronal, and midfacial crown levels were significantly lower compared to Group B. Soft tissue thickness (STT) increased over time in both groups, with a slight increase in Group B. The Pink Esthetic Score (PES) also improved with recall visits at each evaluation.
Conclusion: Zirconia abutments provided superior esthetic outcomes compared to pink-anodized titanium abutments, with significantly lower color differences (ΔE) and higher Pink Esthetic Scores (PES). Although pink-anodized titanium abutments showed increased soft tissue thickening with time, zirconia abutments remained the more favorable option for esthetically demanding cases.
目的：由于粉红阳极氧化钛和二氧化锆基台之间的比较证据有限，实现最佳美学仍然具有挑战性。本临床研究的目的是评估粉红色阳极氧化钛和二氧化锆基台在美学区域的光学效果。方法：选择22例上颌美观区无牙，近端和远端有牙的患者行种植手术，同时进行硬软组织隆胸。A组采用粉红色阳极氧化钛基牙配层状二硅酸锂单冠。B组采用相同材料的二氧化锆基牙。以对侧天然牙为对照组。使用分光光度计评估光学结果。记录CIELAB颜色坐标（Commission Internationale de l’eclairage）以计算ΔE值。使用游标卡尺和根管锉测量种植体周围软组织厚度。采用22个单牙种植体冠的数字图像进行粉色美学评分（PES），评估周围软组织的美学。结果：氧化锆基牙（A组）的光学效果优于粉红阳极氧化钛基牙（B组）。与b组相比，A组种植体周围软组织、冠状面和面中冠水平的ΔE值显著降低。两组的软组织厚度（STT）随时间增加，b组略有增加。每次评估时，粉红色美学评分（PES）也随着回忆访问而提高。结论：氧化锆基牙的审美效果优于氧化钛基牙，颜色差异明显小于氧化钛基牙（ΔE），粉红审美评分（PES）较高。虽然粉红色阳极氧化钛基牙随着时间的推移软组织增厚增加，但氧化锆基牙仍然是对美观要求较高的病例更有利的选择。临床试验登记：（CTRI号）CTRI / 2024/03/064442)。
