This paper aims to evaluate the effect of splinting during implant impression. A master model with two fixtures at the sites of 45 and 47 was used. 20 impressions were made for all four techniques: (A) indirect; (B) direct, unsplinted; (C) direct, splinted; and (D) direct, splinted, sectioned, and re-splinted. Splinting was undertaken with autopolymerizing acrylic resin (AAR). Horizontal distance between fixtures was compared using a digital caliper. The difference in distance were analysed with one-way ANOVA. Group A showed a significantly lowest accuracy among all techniques (p < or = 0.05). There was no significant difference of accuracy among the groups using direct techniques (p > or = 0.05). Group D was more accurate compared to group B and C. We conclude that splinting of impression copings would be beneficial to obtain an accurate impression.
本文旨在评估种植体取模过程中使用夹板的效果。使用了一个在45和47位点有两个种植体的主模型。对所有四种技术制作了20个印模：（A）间接法；（B）直接法，未使用夹板；（C）直接法，使用夹板；（D）直接法，使用夹板、分段并重新夹板固定。使用自凝丙烯酸树脂（AAR）进行夹板固定。使用数字卡尺比较种植体之间的水平距离。使用单因素方差分析分析距离差异。A组在所有技术中显示出显著最低的准确性（p≤0.05）。使用直接法的各组之间准确性无显著差异（p≥0.05）。与B组和C组相比，D组更准确。我们得出结论，印模帽的夹板固定有助于获得准确的印模。
