Abstract

Purpose: To evaluate the influence of abutment material, cement thickness, and crown type on the esthetics of implant supported restorations.

Material and methods: Sixty specimens were prepared to represent 6 abutment groups; Group PA = Pink-anodized Ti, Group GA = Gold-anodized Ti, Group T = Non-anodized Ti, Group H = Hybrid (Ti + zirconia), Group P = PEEK (Ti + PEEK), and Group C = Composite resin, (control). Crown specimens (n = 120) were 2 obtained from Vita Enamic (VE) and Vita Suprinity (VS). Two cement thicknesses (0.1 and 0.2 mm) were used. The color values of crown configurations were measured and ΔE00* values were calculated. Statistical analyses were included Shapiro Wilk, 3-way ANOVA and Tukey HSD tests (P ≤ 0.05).

Results: Abutment (P < 0.001) and crown materials (P = 0.001) had a significant effect on ΔE00* values, while cement thickness did not. Groups PA and H resulted in significantly lower mean ΔE00* values than other abutments, whereas Group T revealed the highest. Unlike VS, cement thicknesses created a significant difference on the ΔE00* values for VE (P ≤ 0.05).

Conclusions: Pink-anodized Ti or hybrid abutments for VE and pink- or gold-anodized Ti for VS seem to be better options, in terms of color change. Cement thickness of 0.1 mm resulted in higher ΔE00* value than 0.2 mm for VE (P ≤£ 0.05). Int J Prosthodont. 10.11607/ijp.8564.

基台材料、骨水泥厚度和牙冠类型对种植体支持修复体最终颜色的影响。

目的：评估基台材料、粘结剂厚度和牙冠类型对种植体支持修复体美观的影响：制备了 60 个样本，代表 6 个基台组：PA 组 = 粉红阳极氧化钛，GA 组 = 金阳极氧化钛，T 组 = 非阳极氧化钛，H 组 = 混合型（钛 + 氧化锆），P 组 = PEEK（钛 + PEEK），C 组 = 复合树脂（对照组）。牙冠试样（n = 120）来自 Vita Enamic（VE）和 Vita Suprinity（VS）。使用了两种粘接剂厚度（0.1 毫米和 0.2 毫米）。测量牙冠配置的颜色值并计算ΔE00*值。统计分析包括 Shapiro Wilk、3 向方差分析和 Tukey HSD 检验（P ≤ 0.05）：结果：基台（P < 0.001）和牙冠材料（P = 0.001）对 ΔE00* 值有显著影响，而骨水泥厚度没有影响。PA 组和 H 组的平均 ΔE00* 值明显低于其他基台，而 T 组则最高。与 VS 不同，水门汀厚度对 VE 的 ΔE00* 值产生了显著差异（P ≤ 0.05）：结论：就颜色变化而言，粉红色阳极氧化钛或混合基台用于 VE，粉红色或金色阳极氧化钛用于 VS 似乎是更好的选择。对于 VE 而言，0.1 毫米的水泥厚度比 0.2 毫米的水泥厚度产生的 ΔE00* 值更高（P ≤£ 0.05）。Int J Prosthodont.10.11607/ijp.8564.

期刊介绍： Official Journal of the European Association for Osseointegration (EAO), the International College of Prosthodontists (ICP), the German Society of Prosthodontics and Dental Materials Science (DGPro), and the Italian Academy of Prosthetic Dentistry (AIOP) Prosthodontics demands a clinical research emphasis on patient- and dentist-mediated concerns in the management of oral rehabilitation needs. It is about making and implementing the best clinical decisions to enhance patients'' quality of life via applied biologic architecture - a role that far exceeds that of traditional prosthetic dentistry, with its emphasis on materials and techniques. The International Journal of Prosthodontics is dedicated to exploring and developing this conceptual shift in the role of today''s prosthodontist, clinician, and educator alike. The editorial board is composed of a distinguished team of leading international scholars.
